Making Crazy Trike 250cc

I used a 250cc engine for buid, the engine has four forward gears and a reverse gear, the wheels are derived from the quad bike, the front is from the motorcycle. I bought all the parts used from auction sites. I have no experience in building such vehicles, so the work on this trike motorcycle took some time, but the end result is satisfactory, riding this motorized trike is great fun :)
