Put a 30 tooth on my 07 1200R and 70 mph is around 3200 or 3300 rpm.

No belt change but the speedometer will be off about 5 to 6 mph. I used a Dakota Digital speedometer calibrator to correct the error.

The DD calibrator is easy to use and must remain on the bike. You will have to splice it into the harness as the plug is for use on big twins. Easy instructions to use and follow come with it.

Good luck.
