Long time listener, first time caller.
I've got an 03 Kaw 636 that I purchased that was already set up with tall gears. I'm shipping it to Daytona for bike week and want to change the gearing back closer to stock. My question is- will 05-06 636 sprockets fit an 03? I wouldn't mind the extra 3 teeth in the back (43vs40) and I'm pretty sure I won't need all the top speed to keep up with the Harleys.
Thanks in Advance for your help.

 

Yes, the 03-06 Sprockets are the same. The front sprockets changed in 07-15. The Rears are the same for all years 03-15.
