Overview
- BSA displayed what it described as a production‑spec Thunderbolt 350 at EICMA 2026, signaling a shift from concept to near‑production hardware.
- The Thunderbolt uses a 334cc liquid‑cooled single with about 29–30 bhp and a six‑speed gearbox, and the same engine architecture underpins the Bantam Scrambler 350 and Bantam Bobber 350.
- The adventure‑focused Thunderbolt is fitted with long‑travel USD front forks, a 21‑inch front wheel, cross‑spoke wheels, a roughly 16.5‑litre tank and rider aids reported as traction control plus dual‑channel ABS with Road, Rain and Off‑Road modes.
- BSA said European showroom availability has moved to 2027 and has not confirmed India launch dates or local pricing, so final production specs and market timing can still change.
- Published production figures differ from the concept — outlets report a wet weight near 202 kg and a seat height around 830 mm — and the bikes form part of Classic Legends’ strategy to compete in the sub‑500cc lifestyle and beginner segments in Europe.
