The swingarm was purchased off ebay. They are sometimes tricky to find, but with a little patience you can find the some real gems. I had looked at having one made, I called about 5 different shops and they were all about $700 if you want to go that route (I have links to several shops that have swingarm jigs for our bikes). I'm trying to do this on a budget, so I searched and searched.
The swing arm is 8" over and was originally designed to be solid mounted. Its currently at a local machine shop getting milled out to take my stock swingarm sleeve & bolt, along with widening the axle blocks to take a larger axle.
The rear rim is 6" with a 200mm tire and came off a 99-07 haybusa. I'm also going to run a hayabusa brake caliper and bracket and I pretty sure I have a caliper torque arm that will fit.
530 EK chain. Rear sprocket is 40 tooth from Vortex (ebay) and the front is 5/8 offset 16 tooth from D&G chasis. And a clutch release kit from PMFR to accomodate for the offset sprocket.
Shocks are off a 2005 ZRX. Freebie! Had a friend with a zrx who swapped his shocks for Ohlins, so got lucky on that deal.
LOL! I'm in no way a secret race team. If you couldn't tell from the pictures, I'm building this thing in the dinning room of my apartment. So I can watch TV and work at the same time LOL!
Getting my swingarm back tuesday and once that gets painted and mounted, that'll probably be it for this year. I had wanted to be finished by now, but finding inexpensive parts is a long exhausting process. I have some ideas for next year (when the weather turns cold again), but for now its time to get out and ride.
