I think that's all about to changed. The newer version of the RB 1005-RC is a real power horse. The 01005-RC engine features a newly developed 8-port sleeve (including our world famous M.E.S.), a new forged and redesigned piston, a newly designed and selected combustion chamber, a new hybrid main bearing, a new front bearing, all smartly presented in a stylish black crankcase with a newly designed cooling head.
