Just like with the 600 vs the 1200, I like the silver engine with the silver (or grey) and black bikes, but would prefer a black engine with the red or blue bikes.
For those that don't know, the 2nd gen 600's had silver (or gun metal grey) engines and the 1200's had black engines. For the W/C 3rd gen, both the 650 and 1250 have silver engines (in the '07 line in Canada).
Regardless, I'm glad to see the 1200 still in the US line. No indication on the Suzuki Canada site of any '08 introductions yet.
