Crankshaft, connecting rod assembly DOPPLER S1R race origin scooter PIAGGIO / GILERA (Typhoon, nrg ...)

Here is one of the best value for money on the market! The DOPPLER S1R crankshaft is a reinforced, balanced and full-mass model, it is really intended for the reinforcement of the low engine and for performance. The steels used are of the highest quality, they are treated and well hardened, the balancing is dynamic and really neat! When we talk about finishing at DOPPLER, we do not skimp! The finish is really perfect for such a price. The connecting rod is placed on a reinforced crankpin and a well increased cage with anti-friction shims.

Aluminum caps obviously cover the balancing holes. For more pre compression, the masses are extremely full. The greases are obviously reviewed and corrected too. The connecting rod is a very high-end model well designed, mode of manufacture casting. In short, this crankshaft will withstand most highly equipped engines, it offers excellent performance and resistance to height. For the highest revs and the most efficient engines, we will still prefer to use ENDURANCE but still more expensive! The rod size, the stroke, the diameter of the bristles remain as the origin.
