BSA have expanded their 334cc Bantam family at the EICMA show in Milan with two new models – the Bantam Bobber 350 and Bantam Scrambler 350 – plus a higher-spec Bobber SP, all due on sale in 2027.
The newcomers sit alongside the Bantam 350 roadster launched in 2025 and share its liquid-cooled, DOHC single-cylinder engine. UK prices are yet to be confirmed, though for reference the Bantam 350 costs £3499 plus on-the-road charges, a figure BSA have described as “introductory”.
Also on the stand was the Thunderbolt adventure bike , wearing new colours and a revised spec sheet. BSA now say it, too, will go on sale in 2027 – when MCN reported its reveal at EICMA 2025, it was due in UK dealers from the middle of 2026.
The Bobber is a single-seater with a low 742mm perch, 58mm lower than the Bantam 350’s 800mm. Power is a claimed 27.8bhp at 8000rpm with 19.5lb.ft at 6000rpm, driving through a six-speed gearbox and chain.
The standard bike runs 41mm telescopic forks and a gas-charged rear monoshock with seven-step preload adjustment, on a 100/90-18 front tyre and 150/70-17 rear. Braking is by a single 320mm front disc and 240mm rear with dual-channel ABS. The wheelbase is 1500mm, the tank holds 13.2 litres and BSA claim a 189kg wet weight. The launch colour is red and grey, with more “coming soon”.
The SP – for Special Parts – is billed as a special edition and adds a dark chrome finish, gold 41mm upside-down forks, 16in spoked wheels and a colour TFT dash. It wears chunkier 130/90-16 front and 150/80-16 rear tyres, but engine, wheelbase, seat height and claimed weight are unchanged from the standard bike.
BSA say the Scrambler draws on the 1966 BSA Bushman, an off-road model they describe as a “high-clearance desert sled”, and uses a new engine designed to save weight. It’s quoted at 28.6bhp at 8100rpm and 22.1lb.ft 6750rpm, with gearing tuned for low and midrange torque.
It rides on 36-spoke wheels – 19in front, 17in rear – in semi-knobbly tyres, suspended by a gaitered telescopic fork with 150mm of stroke and twin rear shocks offering five-step preload adjustment and 130mm of wheel travel. That’s a useful increase on the roadster, which has 135mm of fork stroke and 100mm at the rear.
A 320mm floating front disc and 240mm rear disc with ABS handle the stopping, and the rest of the numbers read 812mm seat, 1403mm wheelbase, 12.5-litre tank and a claimed 184kg wet. Colours are black, green or grey.
A year on from its EICMA reveal, the Thunderbolt adventure bike now comes in black and yellow, grey, or green and ivory, and BSA mention traction control and three ABS modes.
Its spec sheet has also moved on from the figures MCN reported in November 2025. Seat height rises from 815mm to 830mm, the tank grows from 15.5 to 16.5 litres, and the forks are now listed as 43mm upside-down units rather than the 41mm items previously quoted.
Power is now given as 28.6bhp at 8100rpm and 21.8lb.ft at 6750rpm, against last year’s 29.16bhp at 8000rpm and 19.2lb.ft at 5800rpm – although BSA say these figures are approximate and still to be confirmed. The Thunderbolt weighs a claimed 202kg wet, has a 1465mm wheelbase and runs a 90/90-21 front tyre with a 140/80-17 rear.
BSA’s spec sheets for all three bikes list a three-year, unlimited-mileage warranty on their Euro 5+ models.
