The bottom bar with the C in it is actually the lowest bar. If you live in a hot climate, that bottom bar might always be on even if the engine is air temp. Three bars is right in the middle and that's where mine runs most of the time. It can go to 4 bars. It might go to five bars if it's sitting still at an idle for a while. I only saw 6 once and that was when I was doing AFR tuning without a fan blowing on the radiator. The only time it wouldn't rise above 2 bars was in the dead of winter when I started it on a subzero day. The bike idled over 20 minutes and the gauge wouldn't go past 2 bars.
A full system exhaust made mine run noticeably cooler. I saw 4 bars more often with the stock exhaust.
