Been thinking A LOT about building a custom two-stroke motard. :D

I've got a nice 1987 RZ350, completely bone stock. I REALLY hate to strip it down to build a custom, but it's probably the best thing to do. It's already registered and plated here in California, so that will avoid a lot of future hassles.

So, now is the time for planning the build. Any ideas you guys may have would be much appreciated. I'll post up my ideas, and will get the work started when I feel comfortable with the design.

I want to use the existing RZ350 frame and engine, beyond that - it's wide open!! Soon, I'll post pics of the bike as it is now.

Here is a custom motard built with the same engine and frame:

Looks Bad Ass, I question the chain angle , over the pivot. In the one picture, it does not look good. Love this bike though!

I am a Huge fan of this idea. Please run dirtbike plastics like the bike in the pic. That would be really cool. DO IT. :voodoo:

Well that's cool. I like the way you think bud ;) . So are you looking to run the dirtbike plastics and all that as well?
Still up in the air.... For the moment (haven't considered bodywork, yet) I'd like to go with the tank, seat and radiator cowl like in the following pic. I really like how the radiator cowl works with the engine shape, and the position of the fuel tank is crazy.



I would rather run a low front fender like the dual-sport style:



If I could chop the rear fender and chop the number plate (to fit the mufflers on the incline), that would be okay, but it also needs a place to mount a plate, so a custom tail is probably necessary.

I wouldn't run any factory stickers. I would have my own nasty ones made. :shockerknucks:

At first I was concerned about the steel tube frame, but there are a lot of modern bikes using tube frames.



I definitely want spoke wheels. :rock:

Like your not spending enough money on the street smoker lol, jesus man I want your credit line
I'm sick of seeing this bike sitting in the garage, and I hardly ride it. I want to turn it into a bike I really want. I paid at least twice what it's worth because it's an OEM creampuff, and now I'm going to strip it down. I'm not very good when it comes to my finances. :nuts:

I'm into planning for this bike, but I'm not going to spend a lot of time on building this bike before the fighter bike is done. It's good to have a firm plan early on, because then I can watch for good deals on parts and think through problems.

Are you dead set on using the stock frame? I feel for the long travel rear suspension the swingarm pivot is too far from the counter shaft.

Hope you do it though.
Yeah, I know what you mean, but this bike isn't going to see double jumps or table tops. :D

I wish, but it's just going to see light duty off-road, and moderately crazy street riding. I'll also be shortening up the ride height and travel a little, since it's mostly for street use. I should have made it clear that I'm not building a race bike.

This is not the same bike from page one. This bike is a TZR250. Must have been built by the same guy in Germany.

The countershaft to swingarm pivot center-to-center looks like a little less than 5 inches.
