Here is one of the best quality / price / performance ratio! The DOPPLER ENDURANCE crankshaft is a reinforced model, dynamic balancing and full masses, it is really intended for reinforcement of the low engine and performance, it is certainly the most studied crankshaft on the market for this price.
What are the differences with the ER1? The connecting rod, the materials used…. More clearly the reinforcement and the balancing which are even more neat! 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. Blue anodized aluminum caps 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. One of the bristles (bearing housing) is increased in Ø20mm in order to reinforce the lower engine assembly. In summary, this crankshaft will stand up to most heavily equipped engines, it offers excellent performance and strength to match. DOPPLER did not forget to increase the needle cage of connecting rod small ends in Ø12X16X16mm against 12X15X15mm for the origin.
