A buddy walk into the office with an article about a yz500F, that we'll never see in the states, but would like to know if there is a bore kit for the 426 ?

I think this is the Rinaldi Yamaha bike in europe.
They built cases and a crank.
I think 2mm is the max bore os and also the max stroke with the stock stuff.
I think it would be around a 460.
There is a thread on this bike including pictures...

What is the limit on cc's in the AMA 250 class for 4-strokes? I believe it's different than the European rules. Is the 4-stroke limited to 250 cc's in the 125 class?

I think it will be set @ 450cc in the 250 class but, is it the same rules for open class desert ?
