This machine started life as a 2007 YZ450F (we used main frame, engine cases, forks etc) and we then rebuilt the whole bike frame up using our trike kit along with NEW various aftermarket parts. This is 100% ready to ride - you can follow the whole build on our youtube videos of the start to finish process. We used all of our billet parts, along with high end aftermarket pcs. This has been fully rebuilt from engine to frame, along with custom coatings and graphics. This machine is kick-start only , it was built from a motocross bike designed for off-road private track use only.
