Myrons Mopeds

Left and Right can be Reversed

Left and Right: Never assume that the left crank or pedal is a left type, or the right crank or pedal is a right type. They can be reversed, and they often are! Always look for markings that say right or left. Look at or test the threads to see if they are right-hand or left-hand threads.

Righty Tighty: With the outer end of the pedal facing you, a right pedal tightens clockwise and a left tightens anti-clockwise.  

Markings: Most modern pedals and reproduction pedal cranks are stamped L or R. Most vintage European right cranks are stamped D (droit, destra, desno, derecho) or R (recht, right). Some vintage European left cranks are not marked, and some are stamped S (sinistra) or G (gauche) or L (levo, left).

Offset: Ideally the pedal arms should have enough offset to not hit anything, even after being bent inward a little, yet not have too much offset. Too much offset causes the pedals to hit the ground sooner when leaned over, and to stick out more when parking or storing, and to hit the riders feet more when backing up.

Length: Longer pedal arms provide more leverage. For mopeds the pedals are mainly used for starting the engine, rather than pedaling. So if the engine turns over easily then long pedal arms are not needed. Longer arms hit the ground sooner when leaned over. And when not pedaling, one foot is more forward and the other is more back. So shorter arms are better, in many ways. But for pedaling, longer arms are better, especially for riders with long legs.

Style: Some engines or bikes need cranks that “go outward right away” because something is sticking out near the pedal shaft. This is the style #3 or #0 on Sachs 505, Morini MO1, MO2 and Garelli Gulp, VIP engines and certain bikes that have covers or body panels near the pedals.

Pedal Crank Arms for Sale

All of these have a 16mm pedal shaft hole.
Green price is new, dark green price is used

Note: The 433 pedal arms have a 9.5 mm pin hole, but they require a 9.0 mm pin. They also require grinding of the shaft hole 1 mm bigger. On these the grinding has been performed and is included in the price.

1. 435L, 435R originals on Morini MO1, MO2. These cranks are the type that “goes outward right away”, because the engine sticks out close to the pedal shaft.

Note: 502 pedal arms have 9.5 mm pin holes, but the holes are 1 mm closer to the pedal shaft. So they need 9.0 pins ground 1 mm thinner on the flat side. Price $7 each.

1. 503R on ’76-78 Cimatti
2. 502L, 502R compared with 603L, 603R
3. 502 set on Garelli Gulp
4. Garelli Gulp requires #3 style arms that go outward early with a high offset.

Note: 513 and 514 pedal arms have 9.5 mm pin holes but require 9.0 mm wedge pins.

1. 512L, 512R for Sachs 505 engine, on Hercules. Here are the #3 style vintage German original pedal cranks on Hercules mopeds with Sachs 505 engine, such as the US-model “Sachs Balboa”. On a Taiwan moped with a Sachs 505 engine, such as “General 5-Star ST”, the pedal cranks are Taiwan made compatibles, that look different but have about the same dimensions and same style. These “go outward right away”, not to clear the engine, but to clear the covers above the engine, when the crank is vertical.
2. 514L, 514R for ’86-17 Tomos, on ’09 Tomos. Here are the #4 style original pedal cranks on 1986 and later Tomos mopeds, from late A3 to A35 and A55 engine models. The 2009 Tomos A55 engine pedal shaft is much longer than it needs to be, by 3/4″ on the left, and 1 3/4″ on the right, as you can see.
3. 517L, 517R for ’74-85 Tomos A3. The early 1974-79 early A3 pedal cranks did not have or need much offset.
4. 518R, 518L for ’70-95 Jawa

1. 521L, 521R Motobecane, 2. 521L bent inward. Shown here are the #4 style vintage French original pedal cranks on Motobecane Mobylette mopeds 1972-1980+. On variator models, like 50V, the engine swings back as the bike speeds up. The clutch wheel often scrapes against the left pedal crank. On non-variator (Dimoby) models, like 50 or 40, the engine does not swing back as the bike speeds up (but it does swing to keep the belt tight). On those models there is also 3/8 inch more space between the clutch wheel and the pedal crank. So they don’t ever hit and scrape the clutch wheel.

 
1. 531R on ’76-83 Peugeot 103. Here is a 2-style vintage French right crank, on 1975-83 Peugeot 103 mopeds. The right arm has sharper bends than left, because the right cover is closer to the pedal arm. The left crank is a 5-style, with a more gentle bend.
2. 614 Puch replica cranks fit Garelli VIP.

 
1. 601L, 601R Derbi Variant. Here are #3 style vintage Spanish crank arms for 1975-1986 Derbi Variant, and 531R Peugeot 103 substitute.
2. 603R ’78-83 Garelli VIP, 3. 603L ’78-83 Garelli VIP. Here are vintage Italian 6-style right and 3-style left crank arms for 1977-83 Garelli Gulp, VIP, and maybe Monza. The left has more offset than the right. It needs the 3 style that “goes outward right away” because the left side of the engine sticks out near the pedal shaft.
4. 606L, 606R Derbi Variant Sport. Here are higher offset 3-style Spanish arms for 1986-89 Derbi Variant Sport. Like Tomos and Garelli the later engines were wider.

1. 611L, 611R 1978-86 Puch. Here are the 0-style vintage Austrian cranks on 1978-86 Puch Maxi and Magnum models. There are also 1-style Puch cranks, on 1968-78 Puch Maxi. Those are the same dimensions except the bend is more sharp.
2. 614 Puch replica cranks, 3. Puch threads are intentionally made weaker. What were they thinking? Pedal cranks for Puch mopeds have about 1/3 of the threads removed by machining. This makes them get stripped easier. The only plausible explanation is Puch was thinking about safety. When a rider forgets where the pedals are, and leans over in a turn, one pedal can hit the ground. If it hits hard enough it can cause a crash. Puch pedals are designed to break away, rather than causing a crash. 

Pedal Crank Service

1. Straightening a crank. The bend forms about 1-2″ inch below the tool. Here it is held high up.
2. VAR pedal arm bender. This has straightened 500 bent arms, saving customers $10,000.
3. Re-threading a crank.

Straightening:

1. With a special tool like the one shown, and two people, a bent pedal crank can be straightened in one minute without any removal. The second person has to pull on the bike the opposite way, by standing hard on the opposite pedal.

2. Without that tool, the pedal only is removed and a long pipe that fits closely over the crank is used to apply torque.

3. For more stubborn cranks, the crank is removed and placed in a large bench vise. Again the pipe is placed over the crank at the right place, and torque is applied. Moped cranks require 100 to maybe 600 foot-pounds of torque to bend. This is done without heating.  

Re-threading: Often just the first few threads become messed up. Bicycle shops have pedal taps, size 9/16-20 Right and Left, that can repair partially-stripped threads on moped cranks. Hardware stores do not have those taps, instead they have 9/16-18, more coarse. So pedal taps are a bicycle-industry-only item. 

Repairing pedal crank threads is done by starting the tap from the good side, which is the back. Sometimes crank removal is required, and sometimes it is optional. Cutting fluid, or at least oil, is applied. The tap is moved back and forth as it is screwed in (like 4 steps forward and 3 steps back), until it goes all the way through.

Rethreading a M14-1.25 crank to 9/16-20 (from 14.0 to 14.3mm) is more difficult. The plated steel is hard and tough. It takes longer and requires more force. The crank arm and tap get hot by the end of the 10-20 minute process.

Morini MO1 and M1 Start Cable

The original start cable conduit stops at, and moves with the start lever, while the inner cable end is fixed to the engine. This is the opposite way most cables are attached. Usually the conduit stops on the engine and the inner wire attaches to and moves with the start lever. The cable is single ended, so it can slide out of the conduit and be replaced separately.

  Negrini mopeds have been made in Italy since 1950.

1. “From bicycle to anti-dive” a history of Negrini, from “Motociclisimo d’Epocha” magazine April 2005
2. Negrini was founded by Pietro Negrini in 1950. The first Negrini mopeds had IMC (Industria Meccanica Calzolai) 3-speed engines.
3. Negrini made 61,632 units in 1960, 132,548 in 1965, and 320,000 in 1970. Pietro Negrini’s son Mauro took over the company in the 70s.
4. Here is Mauro Negrini, on a fishing trip, 65 years old in 2005, still with the passion. Some Negrini’s had CO.ST.A. anti-dive front suspension.

Negrini USA was formed when the US laws changed in 1976, and moped demand in the US was very high because of fear of high gas prices. Some time around 1979 Negrini USA Inc became Marina Mobili, in Moonachie New Jersey.

Other than the Leprotto, all Negrini mopeds had high quality CO.ST.A motorcycle type suspension for precise control. Other than the Leprotto, all Negrini mopeds had high quality Domino “70’s chrome” controls with polished stainless steel (SS) levers that look like chrome. Of course, like an Italian meal is not complete without pasta, so all Negrini mopeds had high quality CEV electrical equipment, Dansi or Bosch ignition, Grimeca wheels and brakes, CBA exhausts, and for desert, Dellorto S.H.A. 14/12 (or 14/9) flat slide carburetors facing to the right side.

Marina Mobili Inc.  The business location on 146 W Commercial Ave, in Moonachie NJ, that was originally called “Negrini USA Inc”, became known as “Marina Mobili Inc” (MMI). The phone number 201-438-5700 that was originally for Negrini USA Inc, became the phone number of Marina Mobili Inc. From this it appears that Negrini USA changed their name to Marina Mobili. The most likely reason is they wanted to expand into selling more brands than just Negrini.

MMI went on to become the biggest independent moped importer in the USA, taking on dozens of brands of bikes and components, mostly Italian and American at first. Soon they expanded to parts from France, Germany, Taiwan, Holland and Spain. So the 1979 flyers below are historically important. This material was donated by Mr. B. Small of Maryland USA, for you to use and enjoy!

Marina Mobili’s first product brands were Bosch, CEV, Cintin, CO.ST.A., Dansi, Dellorto, Domino, G.E., Grimeca, Huret, Kryptonite, Master, Michelin, Minarelli, Morini, Negrini, and Pirelli brands. They are listed on this early flyer for moped dealers.

Symbols and Notes

F is front, R is rear, fr is front and rear 

italic part number means replacement item

price colors are new, new or good-used .

The six parts lists below use this same set of notes.

Note 1. The brake plate has a short round tube that passes through the bearing seal and stops against the bearing. It also seals the bearing grease from getting onto the brake. The front brake is on the left, so the front bearing spacer is on the right. The rear brake is on the right, so the rear bearing spacer is on the left. The bearing spacers stop against the bearings and have a 20mm diameter at the bearing seal.  

Note 2. The brake cam shaft pushes the brake shoes against the drum. It can have two different thicknesses. 1976-78 SL and TT models had 10mm thick cams and 31.12.210 brake shoes (MM# 105251). 1978-on models had 8mm thick cams and 43.12.210 brake shoes (MM# 105252).

Note 3. 43.12.210 (MM#105252) brake shoes have steel plates on the cam end, but 31.12.210 shoes (MM#105251) do not. To make 43.12.210 replace 31.12.210, either the 1 mm steel plates must be removed from the brake shoes, or the 10 mm cam ground thinner to 8 mm.

Note 4. Derbi brake shoes came in two types, hole and non-hole, that interchange. The brake shoes with holes slide over the pivot pin so they can never detach. That improves safety slightly but makes servicing way more difficult. Most makers such as Honda use non-hole drum brake shoes because they’re easier to install. On these Derbi 105 x 25 mm brakes, the hole type interchanges with the non-hole type.

Note 5. The speedo spacer is only for bikes without speedometers. It takes up the same space on the axle as the speedo driver unit would. Veglia speedo drivers take up 3 mm. CEV speedo drivers take up 4 mm.

Note 6. The anchor bar is the bracket that attaches the brake plate and carries the braking force to near the swing-arm pivot. It’s purpose is to isolate the brake action from the suspension action. So going over bumps does not change the braking behavior. Mopeds generally do not have a anchor bar, but motorcycles generally do. The first Derbi models sold in the US 1976-78 did not have it, then they did 1979-80, then they did not again after 1980. For more info see section 5 Controls.

A brake plate for no anchor bar can be converted to work with an anchor bar by 1) adding a 8.5mm spacer, 2) repositioning the lever on the cam shaft, 3) drilling a 8mm hole in the brake plate anchor.

6. Axle Parts Accounting

The sum of the lengths of all of the axle parts must add up to the length of the axle, minus any extra. Adding things up can expose errors and predict unknown lengths.

Rear Corrections: In the SL-SLE-TT, Laguna and C5-RD50 Parts Catalogs the axle parts  take up so much space on the rear axle that the axle nut uses only 4 or 5 of its 8 threads. The calculation exposed this. Derbi compensated for the short axle by leaving out one washer and making another one way thinner. An actual original 1980 Derbi SL confirmed this. Here the illustrations and lists have been corrected to match what is actually on the bikes.

Front Corrections: In the SL-SLE-TT, Laguna and C5-RD50 Parts Catalogs three front axle washers 31.12.310 are listed and illustrated. One is an inner washer, inside the fork and the other two are outer washers. The inner washer is only on bikes without speedometers. So here it is called a speedo spacer. It takes up the same 3mm space on the axle as the speedo driver. The manuals don’t show or explain this. Furthermore the illustrations show it on the brake side, not the speedo side. Here the illustrations have been corrected to match what is actually on the bikes.

Corrected lengths are blue. Predicted lengths are red.

Variant SL, SLE and TT models have a stamped sheet metal frame like most vintage mopeds. Laguna, RD50 and C5 models have a tubular cradle frame like most vintage motorcycles.

Variant SL is shown in olive green. But there are no olive green parts in any of the Derbi Motor Corp of America (DMCA) parts catalogs or price lists. So either olive green SL was not produced or it was made in very small numbers.
