Here is one of the best quality / price ratio on the market and above all the most upscale on the market! The DOPPLER ENDURANCE crankshaft is a reinforced model, balanced and in full masses, it is really intended for the reinforcement of the low engine and the performance, it is certainly the most studied crankshaft on the market. What are the differences with the ER1? The connecting rod, the materials used…. More clearly the reinforcement and balancing which are even more careful! 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 don't skimp! The finish is really perfect for such a price. The connecting rod is a very high-end lightweight model, it is placed on a reinforced crank pin and a well increased cage with anti-friction wedges. Anodized blue 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 manufacturing method. In short, this crankshaft will withstand most well-equipped engines, it offers excellent performance and resistance to match. Doppler did not forget to increase the needle cage of connecting rod small ends in Ø12X16X16Lmm against 12X15X15mm for the origin. This model is specific to GPR DERBI with balancer (balancing shaft).
