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. 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 placed on a reinforced crank pin and a well increased cage with anti-friction wedges. Aluminum plugs obviously come to cover the balancing openings. For more pre-compression, the masses are extremely full. The lubrication is obviously reviewed and corrected too. The connecting rod is a very high-end model, well designed and signed DOPPLER, casting method, 2 lubrication holes at the feet, increased at the head.
In short, this crankshaft will withstand most of the very equipped engines it offers excellent performance and resistance to the height. For the highest revs and the most efficient engines, we would still prefer to use ENDURANCE but still more expensive! The connecting rod size, the stroke, the diameter of the bristles remain as the origin.
