Blade-cooled 43 mm (61 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 bridge of the split exhaust is ground behind to minimize the risk of heat jamming on the exhaust side
- The edges of the overflow ports on the GPO tuning cylinder 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.</li
- The required M6x62 mm stud bolts for mounting the cylinder base as well as nuts, washers and stud bolts for the intake are included as standard with the GPO.
- The angle of the intake tract has been adjusted so that the carburettor and air filter are now aligned horizontally and no longer point diagonally upwards.
- On the BADASS Diablo, the embossed «30 km» logo is positioned off-center, whereas on the GPO Divertimento it is positioned in the middle, as it is on the original Swiss cylinder.
Notes:
The cylinder base is designed ex works for Swiss 50/2 (502) engines. However, the holes for the German 50/2 engine housing are indicated. This allows you to drill them out if necessary and use the cylinder as usual for your moped with German engine housing.
The large inlet allows the use of a 17 mm swiing® tuning carburettor, provided it is fitted with a short air filter cap, suitable clamp (short) and corresponding closing plate (long / deep).
The smaller 41 mm version of the racing kit, the matching 17 mm carburetor and the air filter parts described above can be found in the accessories section.
Good, inexpensive standard spare part. GPO – GOOD PARTS ONLY.
