if you use a sport bike remember to press weight transfer (L1) and forward all the time except turns. It greatly increases your speed when your on a straight away and places where a wheely (doesn't go as fast) would be hard. Also when using a sport bike do a wheely right at the beginning of the race to boost your speed (you probably already knew)
Which is worse? Being hole-punched to death or being eaten alive by the cast of "Friends"?
