The crankshaft DOPPLER Sport is a reinforced model, balanced and in full masses below ER1 models DOPPLER ENDURANCE, it is really intended for the reinforcement of driving bottom and accompany a slightly prepared engine. The steels used are of high ranges, they are treated well and hardened, balancing is dynamic and well cared for! Material that has really surprised us !!!
When talking about finishing at DOPPLER, it does not skimp and this vilo for all models! Named Sport at RRD and ORIGIN at DOPPLER, we preferred the so named because it looks nothing like an original model with its full masses, its reinforced rod ... The finish is really on top for such a price.
The link is placed on a reinforced crank pin and a much increased cage with copper anti-friction wedges. Aluminum caps are obviously cover the balance holes. For more pre compression, the masses are ultra full. The lubrication are obviously reviewed and corrected too. The rod is a well designed high quality model casting manufacturing method then polished.
In short, this crankshaft will resist without problem has origins configurations or slightly prepared the type kit 50cc or 70cc small. For engines requiring more high speeds and highest performance while preference is likewise used the model ENDURANCE or ER1 but even more expensive! The rod size, running, the diameter of the bristles remain as the origin.
