Just in case someone is waiting for a 43 tooth rear to be available for the new 4RT like I was last week, the new Gas Gas rear sprockets will fit perfectly. It seems they're more available and in more configurations. I went with the 44 tooth and am pleased. First is as slow as I wanted and now 2nd is more versatile.

I did the same thing and I agree that the gearing is now ideal. Also installed a 315 clutch reservoir and the change in clutch operation is incredibly better. Took the hint from all of you Brits who have had the 4RT's much longer than your stateside buddies.

Still smiling from first 4rt ride ysterday and was told by dealer that left over stock Pro 42 tooth will fit fine so hoping one tooth will work. The most fun bike on the planet!
