Balancing and weight distribution are optimized to obtain the best performance with the FLR cylinder and the 100cc 2fast FL exhaust.
Very high quality, this crankshaft has a 47mm stroke & a 100mm connecting rod. It is initially intended to be mounted with the 2Fast FL cylinder. You can of course adapt it to another 100cc racing cylinder on the market. We can say in a way that it is ''Plug and Play'' in the 2Fast Passion housing.
