I have the optional wider rear rim so I'm running 120-70-17 (std) on the front and 180 -55 -17 on the rear I was fairly picky when I set the bike up with the Ohlins and even measured "corner weights, front is at 110kg and rear is at 102 kg which is slightly different from standard which was on the original suspension, which was 104 on the front and 108 on the rear. Bike is also slightly hotted up and the "Standard set up" got "too light" in the front when gassing it in corners.Will.
