Domino

July 14, 2014

 DominoDomino controls (comandi) are made in Italy since the 1950’s. Domino controls are found on most Italian mopeds, along with other Italian controls PV, OSL, Ci.Ti. Domino has made, and still does make, many other high quality motorcycle controls.  

In the 1980’s Domino part numbers began with “D”. The “D” parts were for sale to the public through independent distributors. Domino also made controls specifically for Vespa, Garelli, and possibly others. Those parts were only sold through Vespa or Garelli dealers. They never did have a Domino part number. Myrons Mopeds made up the “V” and “G” part number prefixes to agree and mesh with the corresponding “D” prefix items and labels. For example the Vespa version of Domino control “DB2” is “VB2”, and the Garelli version is “GB2”.

Domino 1970s chrome levers and controls

Domino “70’s chrome” moped controls:

VB "60s chrome" brake and decomp control silver

VB “60s chrome” brake and decompression control silver

VA "60s chrome" sliding-block throttle and brake control silver (no throttle spring)

VA “60s chrome” sliding-block throttle and brake control silver (no throttle spring) with bottom kill switch mount

Vespa “70’s chrome” (sliding block): In the 1960’s most countries did not require motorcycle control levers to have balls on the ends. These VA and VB “70’s chrome” controls are the same as the VA0 and VB0 “70’s chrome” controls that follow below, except the tips of the brake levers do not have balls. The lever blades are chrome, stamped from sheet metal. The cast aluminum housings are painted silver. The throttle is a sliding block type, where the twist tube (barrel) has a spiral slot that moves a sliding block back and forth. The sliding block also contains a pinch bolt to attach the cable wire. These are for a 1969 to 1977 Vespa Ciao, but there are many other 1960’s Italian mopeds that were equipped with them. And there are other makes of 1960’s Italian levers, such as Ci.Ti, which are similar.

 

Domino DB0 left control

DB0 “70s chrome” brake and start control silver

Domino 70s chrome right throttle and brake control DA0

DA0 “70s chrome” sliding-block throttle and brake control silver (no spring)

Domino “70’s chrome” (sliding block): In the early 70’s US mopeds had Domino “1970’s chrome” levers. The lever blades are chrome, stamped from sheet metal. The cast aluminum housings are painted silver. The throttle is a sliding block type, where the twist tube (barrel) has a spiral slot that moves a sliding block back and forth. The sliding block also contains a pinch bolt to attach the cable wire. So there is no cable end piece needed at the throttle end. This means the throttle cable is “universal” or “single-ended”. On the other hand, these throttles need frequent lubrication (oil or grease), or they become sticky and eventually wear out.

 

DA0 right control with threads for an M5 adjuster on the throttle cable

DA0 Right control with   M5 adjuster threads on the throttle cable

DA0 right control without threads for an M5 adjuster on the throttle cable

DA0 R control without    M5 adjuster threads on the throttle cable

Because the twist tube is steel and the sliding block is aluminum, it’s the sliding block that wears out first, causing further sticking. This earliest version from before 1978, had no flange or provision for a throttle return helper spring on the twist tube.

Some DA0 right controls have an M5 adjuster as a stop for the throttle cable, and some don’t. The kind without an M5 adjuster may be for early 1970’s Vespa Ciao without a right-handlebar engine stop switch. All of the “V” type right controls made by Domino special for Vespa (Piaggio) do not have M5 threads for a throttle cable adjuster. All of the other “D” and “G” types of right controls do have threads for an M5 adjuster.    

 

Domino DB1 left control

DB1 “70s chrome” brake and start control silver

Domino 70s chrome right throttle and brake control DA1

DA1 “70s chrome” throttle & brake control silver (no throttle spring)

Domino “70’s chrome” (sliding block): These controls are exactly the same as the previous ones, except for the grips. The Domino aftermarket controls have different grips or different housing colors than many of the Domino OEM controls. To get the exact style and color, you had to get the part through the moped maker’s parts distributor network, such as a local Garelli dealer. The Domino controls made to order for a particular maker have a part number that begins with the maker initial. V is Vespa, G is Garelli, and C is Cimatti. The Domino aftermarket parts all begin with D. The Marina Mobili part numbers are used here, from the late 1980’s. They were the #1 moped parts importer/distributor in the United States at the time. 

 

Domino 70s chrome right throttle and brake control DA1

DA1 “70s chrome” throttle & brake control silver (no throttle spring)

GB1 "70s chrome" brake and start control silver

GB1 “70s chrome” brake and start control silver

Garelli “70’s chrome” (sliding block): Before 1977, Garelli mopeds had Domino chrome levers with plain silver housings. The right control was a standard Domino DA1, with no assist spring. The left control was like a DB1, except the Garelli start cable hole was bottomless and threaded M6x1. The grips were D21 and D22 “waffle” style. The threaded start cable hole was also used on later Garelli left controls, GB2 (77-80) and D3BM (79-84). 

 

 

 

Domino "70s chrome" wrap-around throttle

CA0 “70s chrome” wrap-around throttle and brake control silver

Domino DB0 left control

DB0 “70s chrome” brake and engine start control silver

Cimatti “70’s chrome” (wrap-around): From 1976-1978 some US mopeds had Domino “1970’s chrome” levers (1976-77 Cimatti City Bike, 1977-78 Rizzato Califfo, others). The lever blades are chrome, stamped from sheet metal. The cast aluminum housings are painted silver in the 1970’s. The left side control is the same, but the right side has a different type of throttle. This “wrap-around” type of throttle winds the end of the cable around part of the twist tube. There is no sliding block, and much less tendency to stick. But wrap-around throttles require a solder end piece on the cable. That makes the throttle cable not universal, since the inner wire exposed length is pre-set by the lead barrel end at the handlebar. That is in addition to the smaller in-line barrel end at the carburetor, making it a “two-ended” or “double-ended” throttle cable. Most modern motorcycles have double ended cables, while bicycles always have single ended. Mopeds can have either or both motorcycle style 2-end, and bicycle style 1-ended cables.

 

Domino DA2 right control

DA2 “70s chrome” sliding-block throttle/brake  black (with spring)

Domino DB2 left control

DB2 “70s chrome” brake and engine start control black

Domino “70’s chrome” (sliding block): From 1978-1984 some US mopeds had Domino “1970’s chrome” levers. The lever blades are chrome, stamped from sheet metal. The cast aluminum housings are painted black. All of these black throttles worked better thanks to the silver-dollar-sized throttle assist spring. The 1978-on housing was longer, and the metal twist tube had more “inner” length. Plus it had a flange with a spring anchor hole. You can see the extra 1/4 inch of length in the housing, just to the left of the hand grip, and just to the right of the twist tube securing screw. That is where the three-loop throttle assist spring goes. All subsequent Domino sliding block throttles had the throttle return assist spring. 

 

Domino DB3 left control

DB4B “70s chrome” brake and engine start control black

Domino DA3 right control

DA4B “70s chrome” sliding-block throttle & brake control black (with throttle spring)

Domino “70’s chrome” (sliding block): These Domino DA3 and DB3 controls are identical to the previous DA2 and DB2 ones, except for the grip style. This and all subsequent Domino sliding block throttles had the throttle return assist spring. These DB4B and DA4B controls do not have M6 threads for adjusters on the brakes, nor the starting clutch cable. The DA4B right control does have M5 throttle cable adjuster threads.

 

 

 

Domino VB0 left control

VB0 “70s chrome” brake and decomp control silver

Domino VA0 right control

VA0 “70s chrome” sliding-block throttle and brake control silver (no throttle spring) with kill switch mount

Vespa “70’s chrome” (sliding block): Up till 1977, Vespa (Piaggio) mopeds had Domino “1970’s chrome” levers  with silver painted housings. These throttles did not have the throttle return assist spring. So they tended to stick easier, especially when they needed lubricant. Instead of a “three finger” start lever, like most other left controls have, these have a “one finger” decompression lever. It does not need to be squeezed hard like the clutch start levers do. The engine starts when the decomp lever is released.  The Vespa VA0 throttle and brake control has a bottom mount for an integrated engine stop button. Both VA0 and VB0 controls have a M6x1 threaded hole for the 6mm brake cable adjusters D29, but not for the decomp.

VA1 “70s chrome” sliding-block brake and throttle control grey (with spring)

VB0 "70s chrome" brake and decomp control grey

VB1 “70s chrome” brake and decomp control grey

Vespa “70’s chrome” (sliding block): From 1978-1984 Vespa Grande, and from 1980-84 Vespa Si mopeds, without turn signals, had Domino “1970’s chrome” levers with plain grey painted housings. These throttles also had the helper spring, visible just left of the grip. Instead of a “three finger” start lever, Vespa moped left controls have a “one finger” decompression lever. It does not need to be squeezed hard like the clutch start levers do. The engine starts when the decomp lever is released.  Both VA1 and VB1 controls have a M6x1 threaded hole for the 6mm brake cable adjusters D29, but not for the decomp. 

 

GA1, GB1 "70s chrome" diamond controls silver

GA2 “diamond chrome” throttle and brake control silver (with helper spring)

Garelli start cable aftermarket installed

GB2 “diamond chrome” brake and start control silver

Garelli “diamond chrome” (sliding block): From 1977-80 Garelli mopeds, for sale in the US, had Domino chrome levers. The housings were silver with a diamond shaped mount for an integrated switch. The Garelli GA2 throttle had an assist spring. Everything else was the same as the Domino diamond controls, except the Garelli start cable hole was bottomless and threaded M6x1. The grips were D21 and D22 “waffle” style. These were the first controls on mopeds with provisions for integrated switches. From 1977 to 79, Garelli made their own “Garelli oval chrome” switches. Those switches got broken easily when the knob was struck. After about 1981 Garelli mopeds had DA3M, DB3M black diamond controls with CEV “diamond” switches. 

Some important “ifs, and’s, or buts”:

Garelli GB1 control has M6 threaded adjuster on the start cable but not on the brake cable lever is thinner.

Garelli  GB1 silver plain, GB2 silver diamond  and  DA3M, DB3M black diamond long controls had an M6 threaded adjuster on the start cable, but not on the brake cables.

Domino DB1 left control did not have threaded adjusters on either cable

Domino DB0, DB1 silver plain, DB2, DB3, DB4B black left controls did not have M6 threaded adjusters on neither the brake nor the start cable.

All Vespa controls have M6 threaded brake cables but not start cables

Vespa VA, VB, VA0, VB0, VA1, VB1, VA2, VB2 had M6 adjusters on the brakes, but not on the start cable.

With all of the various Domino controls, the question of whether the holes for the cables have a bottom, or are bottomless and threaded, has been confusing moped mechanics for decades. You need to know this when you are missing or changing cables. Now the question finally has a precise, but long answer! (the old answer was “some do and some don’t”)

 

 

Domino "70s chrome" brake and engine start control black DB3

DB3 “diamond chrome” brake and engine start control black

CEV switch 8194 installed

DA3 “diamond chrome” brake and throttle control black

Domino “diamond chrome” (sliding block): From 1978-85 some US mopeds had Domino chrome levers with a diamond shaped mount for an integrated CEV switch. Everything was the same except the black housings had molded in switch mounts. 

Many non-US models do not have brake lights. So their Domino housings don’t have threaded holes for CEV brake light switches. Their Domino “70’s chrome” levers do not come with the plate that pushes the button on the brake light switch. Their lever blades do not have the extra little hole punched in them to anchor the brake light switch plate.

 

DA3M "70s chrome" brake and throttle control (longer levers and grips)

DA3M “diamond long chrome” brake/throttle (longer levers & grips)

DB3M "diamond long chrome" brake and throttle control black (longer levers and grips)

DB3M “diamond long chrome” brake and throttle control black (longer levers and grips)

Domino “diamond long chrome”: From about 1980 to 1986 Garelli Basic mopeds, and some others, had long chrome levers with a diamond shaped mounts molded into the black housing for integrated CEV switches. Everything was the same as the DA3 and DB3 controls, except the start cable had a M6 threaded adjuster, the brake lever blades were longer, 155mm instead of 140 or 145, and the grips were longer, 120mm instead of 105 or 110. People with big hands would probably like these controls better.

 

 

Domino diamond chrome left control grey

VB2 “diamond chrome” brake and decomp, grey

VA2 "diamond chrome" throttle and brake control grey

VA2 “diamond chrome” throttle and brake, grey

Vespa “diamond chrome” (sliding-block): From about 1977-80 Vespa Bravo mopeds equipped with turn signals had these controls.   Like other Vespa “V” controls, both VB2 and VA2 “diamond” controls have a M6x1 threaded hole for the 6mm brake cable adjusters D29, but not for the decomp cable.

CEV switch 8191 on Domino square right control

VA2S “square chrome” sliding-block brake and throttle control (with assist spring)

Vespa “square chrome” (sliding-block): From about 1978-84 Vespa Grande mopeds equipped with turn signals had these controls. The Domino “diamond chrome” left brake and decomp control housed a CEV diamond horn button switch. The Domino “square chrome” right brake and throttle control housed a CEV square engine stop and turn signal switch. So the buttons were reachable with the thumbs without letting go of the grips. These throttles had the helper return spring, so they always snapped back when you let go. Both VA2S and VB2 controls have a M6x1 threaded hole for the 6mm brake cable adjusters D29, but not for the decomp. 

 

 

VB3 70's chrome brake and decomp control silver

VB3 “diamond chrome” brake and decomp control silver

Vespa “diamond chrome” (sliding-block): This VB3 left control is exactly like the VB2 control, used on Vespa Bravo with turn signals and Grande with turn signals. It also has M6 threads for the brake cable. The only difference is it is silver, not dark grey. It could be for another Italian “variator” type of moped, like with a Minarelli V2 or C2 engine, or a Morini M101 engine. There are not very many of those. For now it is an “orphan”, a lonely control without a bike to go on.

 

DA5 "diamond chrome" throttle and brake control black

DA5 “diamond chrome” throttle and brake control black

Domino “diamond chrome” (sliding-block): This early 1980’s Domino DA5 black diamond right control is like a late 1970’s Domino DA3 black diamond right control, except for two things. The grip is a D21B “basketball texture”, not a D21R “ribbed”. Both the throttle and brake cables have threaded adjusters, M5 and M6. Since the early 1980’s, Domino has made all their moped controls with threads for cable adjusters, aka adjustable cable stops. This was the earliest Domino aftermarket control with threaded adjusters on all cables. The corresponding left DB5 control would have M6 adjusters on the brake and start cables, to match. No photo is available.

In most illustrated parts lists, the Domino D6 throttle barrel, aka twist tube, is shown as the only type. The illustrations were made years earlier when the D6A spring type did not exist. This has caused confusion that perpetuated into future parts pictures. For example, in the greyscale picture above, the D6 older twist tube is shown, when it should be a D6A with a flange. A D6 has nothing to hook the D23 assist spring onto.

3. L housing silver, made for Vespa  V18

Three of four possible combinations of left control styles exist in Myrons parts department. From this view you can see that some of the cable holes have slotted bottoms, and some are slotted bottomless threaded. The threaded holes require M6 threaded adjustable cable stops, aka M6 adjusters . The holes with bottoms do not need cable stops. On those the bottom of the hole is the cable stop.

With the dozens of Italian moped brands, it is likely that some will use each of these three types. There might even be a fourth type (both threaded) somewhere. So far only the Domino controls for Garelli and Vespa brands are known and documented here. More will follow…

Here are three black diamond left housings, each with different cable hole styles. They look the same from a distance. But the presence or absence of the threads for the adjustable cable stop, can make the left and right sides look the same, or be mismatched at the cable ends.
 
Left, the Vespa “V” type always has the brake hole threaded only.
Middle, the aftermarket type “D” always has neither hole threaded.
Right, the Garelli “G” type always has the start hole threaded only.  
D18B and G18DB have M8 threaded mirror holes, but not V18DG.

Domino “80’s black” moped controls:

 
DB7K "80s black" brake and start control

DB7K Domino “mid-80s” brake and start control

DA7K Domino "80s black" throttle and brake control

DA7K Domino “mid-80s” throttle and brake control

Domino “mid-80’s black” (sliding block): From about 1985-88 some mopeds had Domino “80’s black” controls. The lever blades are black plastic. The cast aluminum housings are black, and have a large space for integrated CEV switches. The sliding block (throttle slide) and steel twist tube (throttle barrel) with flange for the helper spring, are the same as the earlier “70’s chrome”. The Domino grips are the smooth octagon style of the mid-1980’s. 

Garelli mopeds 1985-88 had DA7K, DB7K, “octagon” grips.
Tomos mopeds 1986-91 had DA7K, DB8K, “octagon” grips.
Trac mopeds 1985-1989 had DA7K, DB7K, “octagon” grips.

 

DB8K Domino "90's black" left brake-only control

DB8K Domino “late-80’s”  brake-only control

DA8K Domino "90s black" throttle and brake control

DA8K Domino “late-80s” throttle and brake control

Domino “late-80’s black” (sliding block): From about 1987-early 1990’s some mopeds had Domino “90’s black” controls. The lever blades are black plastic. The cast aluminum housings are black, and have a large space for integrated CEV switches. The twist tube (throttle barrel) is black plastic, for less friction. The D1L  sliding block is different than the previous Domino D1 sliding blocks. The Domino grips are the “texture” style of the early 1990’s.

Derbi mopeds 1987-89 had a DA8K right, and like a DB8K left but with a small decomp lever, and “texture” grips.

Here are the two different Domino sliding blocks, shown with two different views. At left is the 1970’s to mid-80’s Domino type, part number D1. At right is the late-80’s and 90’s Domino type, part number D1L. The older D1 kind is wider, and the “tongue” that slides in the spiral groove of the twist tube is narrower than the D1L kind. Currently the D1 is scarce at Myrons, and elsewhere. The D1L is available, but not many US mopeds had that. You can’t substitute a D1L for a D1, even grinding the tongue, because it is narrower, and will cock sideways and stick. When a sliding block throttle sticks, of course, you first put oil on it. When the “tongue” wears down, one side gets rubbed, and it gets thinner, causing the throttle to stick.
