The Bridgestone S20 EVO Sportbike Tires
The front Bridgestone S20 EVO tire now features a dual-compound tread with a circumferential mono-spiral belt with stiffer five-filament strands in its construction for better stability and wear. The rear Bridgestone S20 EVO tire now has three different compounds instead of two, with the wire strands going from five filaments to two and becoming less rigid for better compliance and more grip.
In order to keep the tire from squirming because of the more compliant construction while also improving lateral stability, the rear tire's bead filler has been anlarged.
The new Bridgestone S20 EVO tire is available in usual Z-rated sizes to fit larger sportbikes, as well as H-rated sizes (which only have a single compound) to fit smaller machines like the Honda CBR300R, Kawasaki Ninja 300 and similar motorcycles.
