Not sure if this helps but i have a wheel set from an 06 600rr. Almost certain they use the same axles. Only thing is i don't care to separate the set. You guys are more than welcome to come take a look at them if interested and can't find just a single front rim. They are mint and will leave the non-matching tires on the rims for you.
