The XR650 Project....
I am a new member and looking for some feedback on my project. I plan to make an XR650 trike. I have already built XR650 and CR500 powered quads and I assure all of you that the XR will smoke the CR and it won't rattle your brain in the process. This is mainly due to the incredible bottom end traction of the XR. The engine is counterbalanced and has almost no vibration.
Of course I would prefer to have the geometry of a 85 250r but due to the engine size, that won't be possible. It is around the size of a 350x. My original plan was to put it in a 350x frame but the need for large radiators and a large oil reserve stopped that. After doing some measuring on the stock aluminum XR frame, I found it to be within a 1/2 inch of the 350x all around, and using the same rake too.
My new plan is to leave the XR engine in the stock aluminum frame (which has an oil reserve in the frame) then fab wider triple clamps for the XR forks and a new swing arm using the stock rear shock and linkage, An after-market electric starter to solve the rearward kick starter problem, And an 06 or newer TRX 450 rear subframe which holds a battery for the electric starter. I'll use 250R plastic if the tank will work. I have attached some pics of the XR. Any feedback, guidance or whatever from members would be cool.
