Just received the latest Cycle News, which lists all the '05 bike models for the US market. There are 4 Husky supermoto versions:
SM510R - 501cc, 241 lbs, Keihin FCR carb
SM610S - 576cc, 299 lbs. Mikuni BST carb
SM610 - 576cc, 280 lbs, Keihin FCR carb
SM630 - 633cc, 256 lbs, Keihin MX carb
The photos are pretty small, but both 610s have turn signals, left-side exhaust pipes, and the right-hand views show engine cases that look different than the SM630. The only 450s listed are TCs and TEs.
I've no idea how accurate any of this is, but I'm sure we'll all find out eventually.
