Here is one of the best value for money on the market! The DOPPLER SR1 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 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 well equipped engines it offers excellent performance and strength to match. For the highest revs and the most efficient engines, we will still prefer to use ENDURANCE but all the same more expensive! The connecting rod size, the stroke, the diameter of the bristles remain as the origin.
