Seems I have went from a 47 rear to a 48 (because it was already on a different rim and tire I put on) and back to the 47. Seems with 47 Im sitting around 5250 at 70 MPH and the bike feels really good at that RPM. Safe to sit at 5250 wish for 2-3 hours at a time to get to the mountains? My Dr was a little more relaxed with the 5 speed but faster gearing.. So just curious, I can't imagine the engine stressing much at those RPMS!
