I own a 1996 GPZ500 (17"front wheel) and find cornering a bit of a handful.Although I have new tyres front and back, the front end seems to wander and feels unsafe. The back seems to be soft and bouncy too.I am not entirely sure what the tyre pressures are supposed to be but i presume they were set up correct when the tyres were fitted (by a reputable bike shop!).I have owned many other bikes but find the GPZ to be the worst for handling.Other areas such as reliability and braking are excellent.
