The Street Twin is our most contemporary, fun, and accessible Modern Classic motorcycle.  Powered by the High Torque 900cc Bonneville engine with its unique character, distinctive sound, stripped-back custom styling and accessible engaging riding experience, the new more powerful and higher specification 2019 Street Twin is the perfect Bonneville for today’s rider.  It’s Triumph’s most successful custom classic bike and, as the brand new updated Street Twin is launched we look at why this iconic modern motorbike is so well loved.


All-new Triumph Street Twin


A quantum leap in motorcycle engine design, the 1959 Triumph Bonneville would come to encapsulate an emerging spirit of cultural freedom, inspiring a new motorcycle movement that included legions of enthusiastic riders from artists, musicians, and movie stars to a whole generation of teenage café racers. The ’59 Bonneville became part of a worldwide soundtrack that helped liberate that new generation, and its spirit lives on today in Triumph’s Modern Classics motorbike range. Central to this range is the Street Twin’s new and updated 900cc higher performance Bonneville ‘High Torque’ engine.


A significant engine upgrade (new magnesium cam cover and new lightweight crankshaft together with its mass-optimised clutch cover and lighter clutch) has contributed to deliver much higher performance, with 10PS more peak power (at 65PS (@ 7,400rpm); a massive 18% more than the previous generation. As its name implies the updated 900cc ‘High Torque’ engine also offers a high peak torque of 80Nm @ 4,000rpm, and a new higher 7,500 rev limit, up by 500rpm.



There’s more to the Street Twin than meets the eye, with a host of state of the art technologies beautifully integrated to enhance the bike’s rideability, safety and control, like new first-in-class Road and Rain riding modes which adjust the throttle map and traction control settings at the touch of a button. Ride-by-wire offers a more intuitive level of control, while liquid cooling reduces emissions and offers a greater fuel efficiency (as a consequence, you can enjoy a high service interval of 10,000 miles/16,000km). In addition, ABS, switchable traction control, accessory fitted Tyre Pressure Monitoring System (TPMS) and a torque-assist clutch provide peace of mind and an enhanced riding experience makes this the most technologically advanced Street Twin ever.



There’s a certain kind of British uniqueness to the rich hair-raising sound of Triumph’s Bonneville twin engine. We feel this is how every modern classic twin really should sound, which is why we’ve tuned the engine and exhaust to deliver the characterful British bark and live up to its undoubted heritage. Rich and full, its tone matches its character and is unmistakable enough to give you all the road presence you could ever wish for.






The new Street Twin’s higher specification equipment delivers even more rider control, enhancing its renowned dynamic and intuitive handling for a fully engaging ride. Now with Brembo front brakes for even better braking performance, cartridge forks and improved rider ergonomics for enhanced rider and pillion comfort, the Street Twin was already recognised by press and owners alike for its intuitive handling, and with this higher specification there’s even more fun to be had.


Noted for its cool British urban stripped back custom style, the new Street Twin enjoys a number of eye-catching high quality updates that add an even greater level of refinement to this authentic Bonneville modern classic. Elegant additions such as new cast wheels with machined spoke detailing, new more contemporary tank badges, new brushed aluminium headlight brackets and more premium instrument styling all combine to enhance the beauty of this motorcycle.


There’s a class leading level of detailing and finish on the Street Twin’s beautifully styled 900cc Bonneville engine, including a sophisticated black paint scheme, blacked out sculpted engine and sprocket covers, original machined engine fins and those all-important Triumph maker’s mark triangle and Bonneville engine badges. Original styling cues, combined with an elegant single throttle body with aluminium finishers, deliver the finishing touches to the Street Twin’s distinctive contemporary look. 


This accessible, customisable contemporary take on a Bonneville has over 140 premium accessories to choose from to enhance the look and capability of your Street Twin and truly create your own custom ride. Each of these 140+ accessories has been designed, engineered and tested alongside the Street Twin motorcycle, so you can always be sure of premium quality and fit that’s tailor-made for your bike. All accessories are even protected by Triumph’s two-year unlimited mileage guarantee, just like the motorbikes themselves.

An extra benefit that makes the Street Twin even more accessible is that an A2 licence kit is readily available, enabling a unique APS twist grip and engine tune, making it even easier to own a genuine motorcycle icon. Fitted by a Triumph dealer, full power can just as easily be reinstated by having the kit removed once you have your full motorcycle license.

The stylish and accessible Street Twin is Triumph’s best-selling modern classic motorbike, and this new generation sets the standard at an even higher level.  Experience for yourself all the power, performance and dynamic handling that this exceptional motorcycle can offer.
