New: Left engine cover shaped with lines and angles. Right cover is still rounded.

New 50cc bore and stroke: In 1969 Morini increased the 4M series cylinder bore from 38.0 to 39.0 mm, and decreased the stroke from 42.0 to 41.8 mm. This increased the displacement from 47.7 to 49.9 cc. At the same time the rings got thinner, from 2.5 to 2.0 or 1.5 mm.

 1984-89

 

From 125stradali.com  Franco Morini and Minarelli engines powered practically every 50cc engine produced in Italy in the 80s and 90s. … We would like to remind the reader that in the early 80’s manufacturers were not allowed to fit more than 4 gears and from 1990 only 3. Fortunately, in 1993 the number of gears became free again, but by then it was the scooters that were in charge.

Morini M1.K

Morini GS

Morini GS (MGX)
From 125stradali.com  The air-cooled version of the GS.A, still featuring the large reed valve. Four-speed gearbox and electronic ignition. 

Morini GS.A (RGT 2nd series)

From 125stradali.com  The GS.A is the liquid cooled, forced circulation version of the GS. Compared to the T50-A, it has a new cylinder with a significantly larger reed valve than the previous one and electronic ignition. The gearbox remains at 4 speeds as required by law.

Morini T4 (RCW-RCX-RGT 1st series)

Morini TA

From 125stradali.com  The Franco Morini TA-50 and T4 had the same engine block and 4-speed gearbox, although they differed in the thermal system, which on the TA was liquid-cooled with thermosiphon circulation. The intake was reed valve for both, but characterised by a rather small reed valve. Ignition was for both of them with points.

1990-99 Morini G.303 (RST)

From 125stradali.com The G303 was fitted from 1990 and although it was the same engine, the gearbox only had three ratios due to the law limiting the ratios to a maximum of three. It should be noted that the G303 also changed the internal gear ratio, with the first two gears close together and the third at rest. If a four-speed gearbox were to be fitted, it was advisable to completely replace the gearbox with that of the previous G304 to avoid excessive “gaps” between second and third gears. 

4-speed

1990-99 Morini G.304 

From 125stradali.com  This is Franco Morini’s top of the range and most advanced engine, practically an evolution of the previous GS.A..
The G304 was a long stroke with a light alloy cylinder with a gilnisil treated barrel, reed valve in the crankcase, electronic ignition, pump for forced circulation of coolant, electric starter (as an option) and automatic mixer. The gearbox remained a 4-speed, as required by the Code.
