2026 BSA Thunderbolt Adventure Bike

The original BSA Thunderbolt was produced from 1962 to 1972. Now, the reborn brand is resurrecting the nameplate for its first adventure bike. Powered by a 334cc single-cylinder, DOHC, liquid-cooled engine mated to a six-speed gearbox, it provides fun on and off-road. A high ground clearance, reinforced bash plate, and integrated exoskeleton provide off-road capability, while features like traction control, three ABS modes, USD forks, a mono rear shock, and a slip-and-assist clutch help handle urban commutes.
