Blade-cooled 41 mm (55 cc) racing kit suitable for your moped / moped with Sachs 50, 502, 50/2, 50/3 or 50/4 engine.
The timing of this racing cylinder is deliberately kept low, which ensures high torque in the lower speed range. This effect is further enhanced by the two-piece exhaust. So that you can enjoy every ride in everyday life without worrying, a «30 km» test disguises the actual performance of your power unit.
The racing cylinder set includes cylinder, complete piston kit, cylinder studs and a cylinder base gasket.
Differences to the original BADASS Diablo cylinder:
- On the GPO cylinder, the web of the split exhaust is ground behind to minimize the risk of heat trapping on the exhaust side
- On the GPO tuning cylinder, the edges of the overflow ports have been chamfered in the area of the cylinder neck to make it easier to fit the piston rings.
- The original BADASS cylinder is supplied with a GOL piston, while the GPO Divertimento is equipped with a GPO piston matched to the cylinder. Differences can be seen, among other things, in the crown and in the cut-outs on the piston skirt for opening the overflow ports.
- In the GPO Divertimento, more space has been created for the nuts to tighten the cylinder base.
