Tires and tire maintenance during the track day/race day are the biggest contributors for a crash. Once you've crashed (hopefully unhurt), you get to blow more $ on track plastic, frames sliders, tank damage, helmet, suit, levers, rear sets, etc.
Best advice for max fun and min $. DON'T SKIMP ON TIRES!!!!!! Or anything associated with tires.
Get some tire warmers...period. (There's a reason every moderately serious race team has them)
Also, go with race slicks. They are stickier and cheaper. (Did he say cheaper.). Yes, cheaper. Every track will wear more rubber on 1 side of tire more than the other depending if it clockwise or counter clockwise. A DOT cannot be "flipped". A slick can be flipped and will therefore get more laps before getting clapped out. They are much higher quality in grip, preventing $ spent on fixing tanks, leather suits, etc.
Dunlops are a very good race tire. Very good grip, last a long time (on a 600cc). (1000cc=more motor, go thru tires faster) also, good grip in heat. Plus, they offer contingency money for podiums.
The Michelin Power Ones are a very good tire also. But, no contingency.
Tried to get Bridgestones to work for me because they also offer contingency. Didn't have the same level of confidence at lean angle as Michelin/Dunlop. The BT increased lap time by 2 seconds/lap. I changed the geo of bike several times to try to increase grip and reduce times...didn't work out for me.
Also important aspect that new riders don't think about, but should is tire pressures. Get optimum tire pressure setting from dealer and check them religiously the 1st half of the day. Mornings are cold and track temp is cold. The track surface sucks the heat out of the tire and changes the pressure in the tire. The front tire carcass must flex and spread out when entering a turn. If pressure is too high, it cannot flex and will lose grip, causing a crash. Right after you return to pit after you 1st 4 sessions of the day, check your tire pressures front and rear. The more aggressive you are riding, the hotter the tire gets and increases the pressure in the tire. If you don't reset the pressure to original recommended setting, the pressure will build in the tire. It will not flex and you will go down.
Word to the wise about tire warmers. When listening to MOTOGP riders, they sometimes lament that they are struggling to get heat into the tire for max grip. Slicks require more heat than DOTs. BUY tire warmers to help get heat into the tires. Put tire warmers on tires first thing after arriving at track. It takes about 30 mins on tire warmers to get tires to max temp on the warmers. Then, they tires are almost up to temp. (A cold morning WITH warmers and its not that hard to go out too fast and wind up on your arse 1st lap, 1st session...track day ruined).
A high quality tire (at the recommended pressure) will save you $ in the long run by having far less crashes. Show them tires a little luv and they will repay you with smiles and make you look like you know what you're doing.
Happy crack days
