Ideal to accompany small 50cc & 70cc kits on your DERBI motorcycle.
Here is one of the best value for money on the market! The DOPPLER ER1 crankshaft is a reinforced model, balanced and in full masses, it is really intended for the reinforcement of the low engine and the performance for an original configuration or small kits 50 & 70cc. The steels used are of high quality, they are treated and well hardened, the balancing is dynamic and really neat!
When we talk about finishing at DOPPLER, we don't skimp! The finish is really perfect for such a price. The connecting rod is placed on a reinforced crank pin and a well increased cage with anti-friction wedges. Aluminum plugs obviously cover the balancing holes. For more pre-compression, the masses are extremely full. The lubrication is obviously reviewed and corrected too. The connecting rod is a very top-of-the-range model, well designed, casting mode.
In short, this crankshaft will withstand most engines equipped it offers excellent performance and strength to match. For more advanced and efficient engine configurations, we will still prefer to use the ENDURANCE model but still more expensive! The connecting rod size, the stroke, the diameter of the bristles remain as the origin. This model is mounted on mécaboites DERBI euro 3 and 4 engines.
