The lighter casing is down to a new production technology, with the three-ply nylon design jettisoned in favour of a two-ply polyester construction. Michelin claims the update has not only reduced tyre 'rebound' but lateral rigidity remains unaffected. And the StarCross 5 tyres also require less 'warm-up' compared to their predecessors. ~ 'Mud-phobia' bars to further enhance tyre cleaning on the Soft option to further prevent soil from building up and reducing traction whatever the conditions. ~ Self-cleaning tread characterised by fine horizontal lines to help release build-up. ~ Lighter casing has reduced weight by as much as 15 percent, The most obvious by-product of trimming the 'fat' is less unspring weight, which has palpable benefits in terms of braking, handling and general manoeuvrability. ~ Run higher tyre pressures up to 3psi more than the old Starcross range without compromising performance. ~ Improved traction in a straight line and more progressive handling in corners. ~ No ‘running-in’ needed as the flexible casing offers great performance from the starting gate. ~ New casing engineered to optimise the size of the contact patch. ~ Aggressive front and rear tread patterns offers maximum levels of grip for precise steering and traction, even when racing in very difficult conditions. ~ Directional intermediate and side tread blocks ensure good steering response from the front tyre and traction from the rear. ~ Central blocks are designed specifically to enhance braking performance and traction on all types of track surfaces. They act like hooks to dig-in and drive the motorcycle forward.
