Bridgestone – Bridgestone Battlax Sport & Classic Radials, including BT011F and BT012R radials, BT020F and BT021F fitments, BT01F and BT54F sizes and TH01F and TH01R radials, keeps a long generation of sport and sport-touring machines properly shod. Radial construction is what made modern sport bike handling possible, using a stiff belt under a flexible sidewall so the contact patch stays put while the tire still soaks up bumps. That combination gives quick, accurate steering and high-speed stability at the same time. Within this range there is real breadth: earlier BT011 and BT020 patterns suit period-correct sport tourers, BT021 and BT54 fitments serve later sportbikes and nakeds, and the TH01 radials cover large-wheel scooter and touring applications in sizes like 120/70R15 and 160/60R14. Common 120/70ZR17 fronts and 160/60R15 rears are here as well. For riders keeping a well-loved machine sharp, matching a proper Battlax radial pair restores the feel the factory intended. Because several of these patterns cover long production runs, double-check the exact code, such as BT021 versus BT023, when ordering a replacement.
