Ok, I got a WR250R without a motor to start the project. The ad said it was without the tank, motor, and cradle. I got a cradle on eBay today. The bad news is that he never told me or put in the ad that the radiators are missing. No big deal I will first try and see if I can cram the Banshee radiators in there. If not I will order up some stockers but I am a LONG way from needing to cross that bridge.

It is at the friends as I type and am finishing up details with the shipping company. Here are the first pics of it at his house.

They get a little bigger if you click them.

Now I am on the lookout for a gently used Banshee quad, maybe an RZ350 but I doubt I could bring myself to cannibalize one of those even though the powervalve would be nice. The WR is a perfect candidate for the project. First, I get to keep it all in the Yamaha family. Second, the bolt together hybrid aluminum/steel chassis is a nice compromise because I should maintain good stiffness, yet frame cutting/welding/modifying of the lower half will be much easier and cheaper. Third, it will be a street legal Banshee powered Supermoto! Do I need another reason besides that?

I definitely have my work cut out for me. I'll be honest. I haven't planned this out much which is very unlike me. I just want a banshee powered supermoto. I'll do my best and if it doesn't work out I'll just slap one of the four stroke singles in there. My main concern is the exhaust. Holy crap! Routing, fabbing, cutting, tacking, welding, cutting it back apart, tacking welding, and so on is going to suck! I don't care though!

Welding put me through college and I miss it dearly so this should be a great project.

Marchesini wheels, dual 4" HID Baja lights, Speed Triple style flyscreen are in the mental plans. Blue, White, and day-glo yellow will be the color scheme. Very Rossi-esque if you will. Obviously this is all subject to change. Long story short. I was lusting over the Aprilia SXV550 supermoto due to the twin and crazy power to weight ratio. Then I thought I could do that myself with a Banshee and a WR and have something far more rare. So that is the goal, a power to weight ratio that is better than or equal to the Aprilia 500.

Let me know if you have any feedback, either positive of negative. I also appreciate any tips or tricks you may have regarding the WR or a Banshee. If you know of a Banshee near East Tennessee then let me know. That is next on the list to track down. I will keep everyone up to speed on the progress. It will be slow.

cant wait to see her done..thats gonna be a ripper!..you could also build the banshee donor motor to be even more of a beast...throw a paddle on her and take her to the dunes as well!..i look for some old pics but i used to have a sand drag banshee that was turned into a triple cyl stroker pushing over 300 hp on alky!built by d&m racing in glendale az....you scored on that wr as well what a perfect start!

Only 300hp? I'm surprised it could even make it across sand!:sneaky

The WR rolling chassis was only $700. Too good to pass up.

It's from harbor. I'm going to weld on a new chock and taller casters and adjusting plates. I want it just a bit taller. I was thinking about swapping the jack for an actuator but it isn't bad and the bike won't be on and off all the time so I am just going to leave the jack for now.

yea i actually use the foot operated one more...its not bad i thought of doing the same thing with a wheel chock but i work on cushman scooters alot for customers and wheel chocks dont work well on them due to the spring location..i just use two tie down straps near the rearsets to hold sportbikes down well...it secures them well

Nope. The chassis I found is a WRR with dirt wheels but I've planned on it bing a street biased supermoto all along.

Updated the welder. This one is a Lincoln V350 pro which can do MIG TIG and stick. Our MIG machine is fine but I'm hoping his will upgrade our TIG capabilities. With the frame and pipes needing to be modified having nice TIG welds will be crucial.
