2Fast, well-known among racing fans, is introducing a new racing kit: 2Fast Cylinder Kit 90cc Yamaha Aerox / MBK Nitro. A high-end "Hyper Racing" kit with 90cc displacement with 50mm piston (13mm pin) with 45.8mm stroke (and 90mm connecting rod).

The top quality aluminium cylinder has 6 transfer ports and a bridged exhaust port. It comes with a modular cylinder head immediately recognizable thanks to its trademark anodized blue cover.

It is easily one of the most powerful +80cc cylinder kits on the market. As such, it is really important to run it with an appropriate high-end racing exhaust such as the 2Fast 86cc or the MXS GP90, a 30mm carburetor (minimum) and a HQ digital internal rotor ignition.

Note: to mount the 2Fast 90cc Cylinder Kit Yamaha Aerox / MBK Nitro you'll have to mill in the crankcase to make room for cylinder base and crankshaft (45.8mm stroke).
