The BSA Thunderbolt ADV 350 was officially shown at EICMA 2025 in Milan, marking the brand’s entry into the modern adventure bike space. Classic Legends, which controls BSA, has confirmed that the bike will enter the Indian market by mid-2026. When it arrives, it will take on well-known rivals such as the KTM 250 Adventure, Yezdi Adventure and Suzuki V-Strom SX.

BSA currently sells only the Gold Star 650 in India. However, the brand is expanding quickly, with the Bantam 350 and Scrambler 650 also getting ready for launch. The Thunderbolt ADV 350 adds fresh energy to this lineup, especially because the original Thunderbolt from the 1970s was known for long touring and basic off-road ability. Bringing the name back for a new-age adventure machine feels like a thoughtful step.
Adventure Style with a Practical Build and Useful Touring-Friendly Features
The Thunderbolt ADV 350 comes with a design made for long rides and rough roads. It gets a tall adjustable windscreen, a sharp front beak and an upswept exhaust that helps during water crossings. BSA says it offers higher ground clearance but a lower seat height, making it easier for many riders to handle.
The motorcycle sits on an exoskeleton frame for added strength. A strong bash plate protects the bottom, while wide handlebars and knuckle guards give better control during off-road riding. The bike also includes modern features that are helpful for daily use as well as touring.
Here are some key features that riders will appreciate:
- Traction control and three ABS modes for Rain, Road and Off-Road
- Digital instrument cluster with turn-by-turn navigation and Bluetooth
- Slip and assist clutch for smoother gear shifts
Suspension duties are handled by USD front forks and a preload-adjustable rear monoshock. One of the biggest highlights is the large 15.5-litre fuel tank. While the mileage is not officially revealed, the expected figure of 28–30 kmpl means the bike can cover around 450 km on a full tank, which is ideal for long-distance riders.
