That Gearing Commander website is pretty neat. I'm actually wondering if I'm going in the wrong direction, as it looks like my top speed RPM wouldn't change much, which is what I'm going for (I've stopped caring much about the low end torque). Now maybe I'm thinking just keep the front sprocket where it is at 17T and just change the rear down to 45T. The graph shows at 50mph:


STOCK = 17T / 50T = 6346 RPM
CURRENT= 17T / 47T = 5965 RPM
CUSTOM = 17T / 45T = 5711 RPM


Whereas if I try my first suggestion or the other:
16T / 45T = 6068 RPM
12T / 34T = 6113 RPM
So the above two aren't really hitting where I'm aiming for.





IF I WENT WITH 17T / 45T combo, could I still use a 520 chain? I've found some info out there but it's a little over my head at the moment so just looking for a direction to look.
