We stock over 12 Cylinder and head related

The cylinder head on a 2 stroke engine has a massive impact on the way the engine works. MRB started making cylinders heads to suit the unleaded fuel we can buy now long before decent fuels were banned. We now offer a range of heads to suit all cylinder kits on the market, included centre squish head for road/race applications.
