Crankshaft, connecting rod assembly reinforced AIRSAL for MBK 51 / motobecane av10 / av7

Here is the cheapest crankshaft on the market and yet of good quality. This crankshaft offered by AIRSAL does not have full masses or special balancing but it will be a very good crankshaft to strengthen your low engine on 50cc pushed kits for example. The masses as well as all the steels have been treated (burnished) for optimal resistance. It is of course sold with its reinforced needle cage allowing it to accompany any kit. We regret that it does not have full masses, revised lubrication or special balancing. For more efficient engines, we will still prefer to use the AIRSAL RACING crankshaft which is certainly more expensive! The connecting rod size, the stroke, the diameter of the bristles remain as the origin.
