    It's a '70, 351W, ZF 5 speed, D60 full width rear, D44 high pinion full width front, discs all the way around, custom dash with centered guage package, bunch more mods. I had a few articles in the first couple of issues of Bronco Driver magazine, kinda let the project stagnate for a while, but back to working on it.

    Literally almost looks production grade. TRX200M. Very cool.
    I would ride that at night, be all stealthy like.....a man can dream.

    Thanks, that's pretty much the idea I had in mind while building it - reused as much hardware, brackets and parts as I could, the parts I fabricated (swing arm pivot brackets, battery box, muffler brackets, bodywork mounts, etc) I tried to make them look as close to factory as possible, and tried to choose the combination of parts and fit them to look as if they'd been designed to work together.

    A lot of it I just got lucky with - the front of the 450r seat fits up real well to the back of the 200X gas tank, the chain sprocket on the 450R rear axle lined up perfectly with the sprocket on the 200m transmission once I had the swing arm in place, the rear master cylinder and resevior fit the new tubes I welded onto the rear of the chassis with hardly any fab work, the '04 450r front hyrdaulic brake lever perfectly matches the '84 mechanical rear cable brake lever - lots of stuff like that just flat worked, without me having to do much.

    Wait'll you see my next project - a "trials" ATC. 125M frame/drivetrain (light, lots of ground clearance, dual-range trans), 200X front forks, 200X rear swing arm, lightweight aluminum wheels....target weight is around 200 lbs.

    did you gusset the frame at all? looks like it might have a few weak spots.

    Could you elaborate?

    I'm not a mechanical engineer, I didn't caculate shear points, polar moments of inertia, or material elasticty - I just fabricated to locate parts where they needed to be, with an eye towards triangulation and overbuilding in areas where I thought there would be a lot of stress (A-arm mounts, rear shock upper mount, etc).

    It's been ridden hard quite a few times since I finished it, both by my son (185 lbs) and me (220 lbs), blasting down trails at top speed, up and down ledges and drop offs, and a few good jumps, with no problems so far other than a cracked muffler mount. I suppose the frame would bend if I snag a tree with a front wheel at 40 mph or so, but even a production quad would be trashed in that situation. Besides, if something happens, it's not like I destroyed a $4,000 quad - I'll just consider it a learning experience and rebuild it better.....stronger....faster.

    thats a nice looking quad!! very nice. im thinking of doing something like that with my tri moto 175. came up short on a jump and folded the forks right under her. LOL. i got an old timberwolf out back it uses struts in the front but that looks easier to fit to the trike fame. i know a company offered a rear suspension kit for the tri 175 but they are hard to find. maybe a blaster rear end?? hope to use 200x seat tank and rear fenders the DS 650 style wheel mounted front fenders. when i start this this winter ill post pics.
    Trikes arent dangerous. stupid people on trikes are dangerous!
