hi new to sportbike riding and when i ride my bike on wet roads it feels like the rear is trying to slip from under me is this normal or is there something wrong. is there something that i can do to stop this. like i said i'm new so i don't ride fast i get this at about 25 to 35 mph. i was told to let some air out of the rear tire to get more traction but this was told to me by a person that knows less then me about bikes. the bike is a 05 zzr 600
