Enhanced Performance
Enhanced for 2021, the latest generation update of the Speed Twin’s 900cc high torque engine retains all the power, character and responsiveness of the renowned Bonneville twin powerplant, now exceeding Euro 5 requirements with lower emissions, and giving great fuel efficiency.

The new Speed Twin has incredible torque from low down, right through the rev range for thrilling acceleration anytime it’s needed, with 65PS peak power arriving at 7,500 rpm and with 80Nm peak torque at 3,800 rpm. Such power and torque are comfortably managed thanks to the ride-by-wire throttle control.

The Speed Twin also comes with a 10,000 mile / 16,000 km – service interval.

For European markets, the Speed Twin can be fitted with an A2 license kit and it can be easily reversed to full power by any Triumph dealer.

Enhanced Comfort and Style
The modern customer style of the Speed Twin 900 has been updated for 2021 with new premium features, including all new cast wheels, a new more comfortable bench seat, new bodywork and improved finish and detailing, with brushed aluminium headlamp brackets.

The headlamp itself is compact and features a signature Triumph bulb cap badge. The rear light is a compact and elegant LED, with a distinctive light pattern.

Timeless Bonneville design DNA and custom inspired, stripped-back minimal bodywork, from the sculpted tank and lockable chrome fuel cap, combined with the Speed Twin 900's compact front mudguard, and new side panel featuring an integrated mesh detail with premium foil tank decals, for a stunning result.

The Speed Twin’s class-leading finish, including new brushed aluminium throttle body finishers and black Bonneville-signature engine covers are complimented by a distinctive finned head and header clamps.

Fitted with Pirelli Phantom Sportscomp tyres for great grip and durability, the new cast wheels add to the overall custom look and feature machined detailing on the spokes.

For Speed Twin riders who want to personalise their motorcycles, there are 120 Genuine Triumph Accessories for adding protection, comfort, style, capability and security.  These include options for luggage, fly screens, grab rail, engine dresser bars, engine protectors, and black or chrome engine covers. All accessories have been designed and engineered alongside the bike, for perfect integration, and tested to the same standards.


High Specification for a confidence inspiring ride
The 2023 Speed Twin 900 also comes with a new 10mm thicker seat that features a new foam mixture for better padding, giving the rider an even more comfortable ride.

Renowned for its accessibility, the new 2021 model has a low 765mm seat height and excellent stand-over width, making it a great bike for riders of all heights and sizes.

The Speed Twin is exceptionally easy to ride, with intuitive, neutral handling, and has a great specification of standard equipment, with cartridge front forks and twin rear shocks, a high-specification Brembo front brake setup with single disc for great bite and feel, and a torque-assist clutch for light, easy operation, a real benefit in traffic around town or on long journeys.

ABS and Switchable Traction Control are fitted as standard – to manage the Speed Twin’s torque when traction is compromised. Two riding modes are available – Rain and Road.  These adjust the throttle map and traction control settings for optimum performance in wet and dry conditions.

The Speed Twin’s stylish clocks come with a classic analogue speedometer, and a digital display and menu system, which is accessed by a handlebar mounted scroll button, for fingertip control while riding.

Other features include an under-seat USB charger, key-fob incorporated immobiliser and accessory fit heated grips and Tyre Pressure Management System capability.
