never seen this before :-/

They are good quads. And parts are remarkably easy to find. I've done my homework on these things and some parts such as tie rods, wheel bearings, and hubs are the same as the TRX250R's of certain years. The frame is basically a Chromoly 400EX frame and the front shocks and A-Arms are the same as 400EX Long Travel. But they were designed with road use in mind so most people put 4:1 rims on them to ease up the steering in dirt. They turn a little rough but not bad when you adjust the stabilizer and add 4:1 rims. Most parts can be bought from a company called GoFasters in Cali.
