Well I have been out riding twice now with my Ninja 300 (93 miles) Must say I love every minute of it. My main concern is like when I'm doing 60 mph or so the bike is winding up at 6k. Is this bad for the bike? I know if my car was running at 6k I would be considered but I have no clue if the bikes are different or not. I want to take a trip down to my buddies house but doing 75-80 on the interstate would wind it up even more. Some light on this subject would be much appreciated. Thanks guys!
