It should fit 05-08 250, 450 and 510 without any modifications. Might even fit older bikes, consult your dealer. The rotor bolts could be different on the hub, SM hub takes 8mm bolt, TE hub 6mm. That was the case on my 06 610.
The front ends on the the Sm's are wider than the TE's. That makes it hard to run the Sm disk and caliper on the Te's...As noted if you use the Sm wheels with the TE disk or aftermarket Sm disk you'll have t drill out the disk mounting to use the 10mm SM disk bolts.
