Well Pit Bikes140 with race cam, oil cooler, ally frame and swing arm, big renthal bars, anti snap levers, quick throttle, spare rear shock and carb parts. I've just changed the oil, it's had about 8 hours use from new. Runs really well, if you look on the WPB website the engine is rated at 17hp. I own other bikes and it's safe to say that this thing does go like stink. It's got some good extras and isn't you me usual out the box Chinese carp. Only issue is the back brake is not fitted, but in with the box of spares. Located in Cheltenham, Gloucestershire. Selling as I've got a few other off road bikes and this really doesn't get the use if deserves! These are the best pics I can get in the light currently.
