Here is the 2FAST crankshaft specially designed for 90cc motorcycles.
Balancing and weight distribution are optimized to achieve the best performance with the 90cc 2Fast cylinder and exhaust.
For the mounting of the crankshaft, it is imperative to mill the engine crankshaft to allow the installation of the crankshaft masses. This crankshaft is compatible with horizontal Minarelli engines such as MBK Nitro and Aerox.
The milling operation of the engine crankcase is mandatory to let the crankshaft masses in, thus ensuring correct installation and optimal performance.
The 90mm 2Fast rods, made in Italy, are known for their excellent value for money and are available for purchase individually at our online shop.
