TSC Traction / Stability / Control The TSC inserts, developed exclusively by Blackbird Racing, are based on a 3d printed nanotechnology, specifically for off-road bike sports. This technology is based on the specialized vacuum effect generated by two parts which significantly modifies the contact between the rider & the bike. This change improves grip, control & stability. The enhanced contact between rider & motorcycle stems from a different flow of air inside the components & on the increased anti-slip effect given by the inserts. Article: Blackbird TSC Seat Cover
