Excellent price quality ratio, here is the crankshaft MVT SPORT for MBK 51. The only crankshaft has adopted a cage with an external diameter increased to 17mm for an axis of 13mm on MBK 51!
It is really intended for low engine reinforcement and performance. The steels used are treated and well cemented, the balance is dynamic and neat.
For more precompression, the weights are full with special coating. The rod is forged, placed on a reinforced maneton and a well increased cage with anti-friction holds.
Lubrication points at the head and foot of the rod have been set for increased reliability. Thanks to its architecture and quality this crankshaft can take a rotation speed 14000 rpm! Careful dynamic balance.
Delivered complete, as in our photo, with its reinforced needle cage.
In short, this crankshaft will withstand most of the equipped engines, it offers excellent performance and height resistance. For engines intended for higher and more efficient speeds, we will still prefer to use the K2 model, which is certainly more expensive but planned to support larger engine configurations!
