The power is amazing. I was going 100km/hr at barely 3,500 RPMs.
Previously on 15 front, 45 back, the bike needs to go up to 4,000 RPMs to match that speed.
Yeah. Check out my post 14326. I just made this mod recently and really like the result. I kept the 15 tooth front and motor is turning 3600 RPM at 100K/hr. Looks like the 16 tooth front gives you an additional 100 RPM drop.
