If the bike's centre of gravity is in the right place for getting around high speed corners fast, it should spin the rear wheel before lifting the front. A lot of guys tolerate that airy feeling in corners which causes them to go a bit slower. Just because a bike wheelies, that does not make it a winner. Most race circuits have corners making up at least half the distance. If your bike has not got the legs, you can get beaten at the ends of the straights. But if you can corner faster, it is not such a problem. Sometimes all it takes to get a bike handling well is to move the motor forward one inch.
