Just wondering what sort of mileage I'd get out of a front and rear on a Kawasaki GT750. It's got a pair of Maxxis Hi-Max that are 3000 miles old - will they last another 2200 miles they're going to get this weekend? The Guzzi and I could kill a rear Bridgestone in 4000 but I've not got through a set on the Kawasaki so would appreciate some data, TOG?
