John,
My '02 RS had 19/43 OEM gearing (way over-geared for performance
riding, but it delivered 46 mpg).
When I changed to 18/43, I thought it a nearly ideal compromise
ratio, and it returned 43 mpg.
Recently, a mechanic cut my new chain too short. Afterwards, when I
installed a rear hugger, the tire rubbed severely. Since the chain
was relatively new, I opted to mount a 17T sprocket for the fix
rather than chucking the near-new chain.
I had always been curious how the 18/45 setup would work out, so
going to the incrementally lower 17/43 ratio accomplished two
objectives. However, I find this ratio too low (for other than
easier wheelies). Since the engine now spins up so (too) fast and
there's so much more bottom-end torque available, it encourages
drastic short-shifting that I find less satisfying. Gas mileage has
now dropped to 40 mpg.
I plan to either go back to 18/43 (2.39) or -- since I still have the
like-new 19T original, 19/46 (2.42) if a 46T cog is available.
HTH,
Mike
