2025 EICMA: BSA Thunderbolt Adventure Motorcycle Revealed

BSA has revealed its all-new adventure motorcycle, the Thunderbolt, at EICMA 2025. Reviving the spirit of the original model, renowned for its touring and off-road prowess and remembered as the final bike built in Birmingham back in 1972, the new Thunderbolt marks BSA's first foray into the adventure segment. The brand also stated that the new BSA Thunderbolt is set to hit the market in mid-2026.

Powered by a 334cc single cylinder, DOHC, liquid-cooled engine, mated with a 6-speed gearbox for transmission. The engine is Euro 5+ compliant, featuring a large 15.5-litre fuel tank, which promises a long range. 

Featuring rugged aesthetics, including a rally-style beak and rear rack, the newest model is geared up for full-throttle escapades with premium traction control and three ABS modes (Rain, Road, and Off-Road). Additionally, it offers a preload-adjustable mono shock rear suspension, slip and assist clutch, and upswept exhaust for better water wading capabilities.

Standing on the pegs remains the preferred approach for tackling rough terrain, and the adjustable windscreen and instrument console help maintain rider comfort. The bike's low seat height, manageable weight, and wide handlebars claim to offer easy handling for a range of riders. Added features like decent ground clearance, a reinforced bash plate, an exoskeleton frame, and knuckle guards provide extra protection when required.

The reveal follows the launch of the BSA Bantam 350 in July this year, along with the long-anticipated BSA Scrambler 650; both models also made their Italian debut at EICMA. Also, the BSA Bantam 350 is hailed as a modern-day bike with classic features; a nod to the original Bantam, which was credited with getting post-war Britain moving again in the 1940s.
