the best tip i could give is never give up in a turn, no matter how much you think your going to fast and your not going to make it never touch the brakes and never stand it up and run off the road, just lean it harder and harder, i've seen plenty of crashes from people thinking they are going too fast, standing it up and running off the road only to crash anyways, when all of them could have easily made the turn even if they didn't think so, i've only seen one person actually crash from taking a turn too fast, but if he had gotten spooked and ran off the road he would have crashed anyways so he did the best thing and leaned it until it let go

i've a number of times had to fight that urge to grab the brakes or stand it up and run off the road because i swear i'm in the turn too fast, but i've always remind myself to trust my tires and i live through the turn only to end up going through it again later 10 or 15 mph faster later on

just remember your tires are better than you are, trust them and they will stick... but also remember to let them warm up before you get hard on the gas, hard on the brakes(specifically the front brake, the rear you can slide around a little, if you lock the front brake your on the ground wondering what just happened), or corner hard, i'd say the second biggest newbie mistake other than getting spooked and running off the road is riding too hard on cold tires, i give them atleast 10 miles of riding to get up to temp and then gradually start stepping up my speed

i'd say those off the top of my head are the two big things, just don't try and do wheelies and if you ride with a group don't feel like they are going to look down on you if you don't keep up
