New with us!

Here is the CGN crankshaft reinforced with full masses specially designed for MBK MAGNUM engine and other machines which require a left-hand thread (epolque breaker ignition, kick start machine, reverse engine with relay box ...). This model is cut in good case-hardened steels, has a polished finish connecting rod. Standard LEFT ignition side thread.

In full masses, this vilo will offer you a good pre-compression for more performance. Thanks to its weight, it will offer you more than excellent inertia and a perceived performance gain! It also received a balancing to allow more high revs.
