This is my spare refurbished Yamaha R1 2007 2008 4C8 engine for my race bikes. Completely standard with £880 worth of new genuine Yamaha original bearings, shells seals etc. prepared by DK racing who has looked after many of my bikes. No clutch fitted as I would have put an aftermarket slipper in from one of my other bikes if required. I’m no longer racing so the spares have to go. Please double check the ancillary fittings are secured, but the core engine is ready to be run in and used. No warranty can be given as you can understand. Check my other items as I have a ported gas flowed head, piper race cams with slotted sprockets for sale too.
