Wtf. My bike has at 12t drive sprocket

[GMP]

I always ran 13/52 on my 250s for a few reasons. The '12 seems to have something about the swingarm (maybe shorter?) that gets the tire into the mudflap more with a 52 on the rear using the same length chain as the older bikes. I'm running 13/51 on the '12 now.

Basically takes first gear out of the picture except for extreme circumstances
keeps second as my main gear in the tight stuff with 3rd still an option for chugging too.

If you dont need the top speed this is a great idea, eliminating the dreaded missed shift into neutral as you go from first to second.
