I don't think the chicken strips show much unless compared on a single bike v another bike with the same tyre. The Bridgestone tyres on my 650 twin lost the chicken strips after about 200 miles and no real angle of lean so I suspect that the flatness of the tyre has something to do with it. To support my theory, if you have a flat tyre, like a cars then after 1 mile there's no chicken strip. How many people who ride on the road have ever got rid of the strip on a front tyre and they seem to be even more profiled than the rear.
Might all be complete bowlocks though
