Tyre Advice: What affects tyre life on a GSX-R1000?
There are four factors that affect the life of a tyre. First, pressures; on your bike it should be 36psi front, 42psi rear. Next, the suspension needs to be compliant enough to help the tyre cope.
If it's set up on the hard side, the tyre will get chewed up rapidly as it does the work of the shock as well as its own. Third, the sort of compound fitted. If your mileage is in the hundreds, not thousands, that brings us to the last factor, our right hand.
You must be riding the bike the way the designers intended, on it hard from every set of lights and winding it on hard exiting your favourite corners. Well done!
