The swing arm parallelogram provides for the vertical swing compensation of the almost horizontally installed engine. If the engine would be screwed directly into the frame, the engine vibrations of the 1st and 2nd order would be hard to bear (mirror trembling, tingling, numb feeling in the hands etc.). In addition, it decouples the frame from shocks caused by uneven ground.
The swing arm parallelogram is therefore indispensable, but often causes some displeasure when riding in a sporty manner. There are two things that must be distinguished:
CHECK WARNING
The engine swingarm has six bearing points and can therefore cause a lot of lateral play of the engine under normal wear. This gives the rear wheel its own steering radius, which makes the handling very unstable and imprecise.
If the engine can be moved significantly transverse to the longitudinal axis of the vehicle, the swing arm should be revised. This is a main focus of the inspector at the next general inspection.
We offer a complete revision kit for this purpose.
SPORTIVE DRIVING
The engine makes a horizontal movement as well as a vertical one due to the parallelogram. This influences the response of the rear shock absorbers.
The movement of the engine swingarm is damped by a large silent rubber.
The standard rubber is trimmed for great comfort and is rather unsuitable for sporty drivers.
MALOSSI
The malossi rubber is much stiffer than the standard part and prevents much of the compensating movement of the parallelogram. This is accompanied by a more precise but also more uncomfortable ride. However, the malossi rubber cannot compensate for the play of the swing arm bearing due to wear (see above).
