This is one of the best value / price! The crankshaft DOPPLER ER1 is a reinforced model, balanced and in full masses, it is really intended for the reinforcement of driving bottom and the performance. The steels used are more upscale, they are treated well and hardened, balancing is dynamic and really neat!
When talking about finishing at DOPPLER, it does not skimp! The finish is really perfect for such a price. The link is placed on a reinforced crank pin and a much increased cage with anti-friction wedges. Aluminum caps are obviously cover the balance holes. For more pre compression, the masses are extremely full. The lubrication are obviously reviewed and corrected too. The rod is a premium model well drawn, cast manufacturing process.
In short, this crankshaft will resist to most equipped engines, it offers excellent performance and resistance to scratch. For engines intended are larger and more powerful regimes still be preferred to use the admittedly more expensive but ENDURANCE model designed to support larger engine configuration!
The rod size, running, the diameter of the bristles are preserved as the original. This model is specific to mécaboite DERBI GPR, driving DERBI euro 1 & 2 with balance shaft / balancer.
