Here is one of the best price / quality ratio and above all a more upscale market! The crankshaft DOPPLER ENDURANCE is a reinforced model, balanced and in full masses, it is really intended for the reinforcement of driving bottom and deliver the performance, it is certainly the most studied crankshaft market. 
What are the differences with the S1R? The rod, materials used .... More clearly the reinforcement and balancing which are even cared! 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 rod is a top lightweight model range, it is placed on a reinforced crank pin and a much increased cage with anti-friction wedges. Anodized blue aluminum stoppers obviously come to 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 very upscale well designed model casting manufacturing process. In short, this crankshaft will resist the most highly equipped engines, it offers excellent performance and resistance to scratch.
