110/70 ZR 17 and 130/70 ZR17.
They should do ok, as long as the spacers are a good fit and the chain line/ wheel dish is good. You'll have to flip the front over too as the disc is on the right.
Someone should Photoshop a mock up of the KLX with the Ninja 250 wheels. Any takers.

 

My buddy's mazda speed 6 would smoke that capri and stang. he'll smoke a corvette too. how much lbs of boost? heh...just kidding

anyway, back to the supermoto rims, DID THE NINJA RIMS WORK OUT!!?!

Anyone call pro-cycle and ask if they could do black rims? The black rims are way sexier. I'll be honest, I've been cheating and still eyeing up the 2008 Yamaha wr250x

 

Yep! Tried it on today! My buddie has a 07 ninja 250, the wheels, tires, brakes.. Everything just bolts right up. Took er down the road for a drive.. Works PERFECT. So fun..
haha
I'm j/k of course.. But seriously, If I didn't add this, would you have gone ahead and ordered those ninja 250 wheels? te he, gutta have a little fun

 

Check this out. Looks like you can put on these alloy wheels, with some spacers and brackets.

Not sure, but I think these are off a Honda 250 model. I will look into this, and let you know. 17x3.00 and 17x4.00 are the sizes, and it looks like thay have the cush drive on the rear.

Wheels installed on KLX250

 

Someone should snap them up. Looks like they come with the spacers and a bigger caliper to match the larger brake disk. You even get an adapter to fit the larger caliper. Cush drive is good.
Can anyone tell how much they are?

 

They are on auction, and right now they are $100.00, but I bet they will end up selling for around $600 - $800, if not higher, plus shipping. I will keep watching them, and can even bid, if someone wants to buy them. We will jsut have to work out some kind of deposit, final payment after the auction. Any takers?
