Hi, I bought a 2006 Suzuki 1200s Bandit, I do find that it runs at obout 5000 Rpm when doing 120Km/ph. Is it possible to get it to run at about 3500Rpm at that spssd by changing sprockets, How do the speedo and rev counter work ? What will the effect on those be ? It will help feul consumption if I can lower the revs at 120Km/ph.
