With its new chassis, non-adjustable Kayaba forks and preload-adjustable twin Kayaba shock set-up (with 20% more rear wheel travel over the old Bonnie), the Street Twin is agile around town offers a plush ride. A well padded seat and relaxed riding position enhances comfort and lets you ride all day with no aches or pains. The Triumph is low enough for feet-down at the lights, but not too cramped for tall riders.
The Street Twin handles brilliantly. The 198kg (dry) machine is light, agile, has excellent full lean stability and acres of ground clearance. The single disc twin-piston Nissin brake set-up has impressive feel and power, too.
The Triumph has an 18” front wheel for retro looks, which takes a bit of getting used to after 17-inchers, so the front end needs more muscle to get into a corner, but once you’re in and powering through, the Street Twin is completely stable.
Triumph claims 54bhp from its smooth new ride-by-wire controlled, liquid-cooled, 900cc ‘high torque’, 270° parallel twin-cylinder engine. That’s more than enough for mischief on a naked retro. Power is up 22bhp over the old out-going air-cooled Bonnie (between 2750rpm and 4750rpm) and the new motor makes 18% more torque. Triumphs claims a frugal 75.5mpg and service intervals have increased from 6000 to 10,000-miles. The new ‘slip assist’ clutch is far lighter than the previous-generation Bonnie’s and the five-speed gearbox is slick and precise.
Although designed and developed in the UK, the new Bonnie range, including the Street Twin will be made at a Triumph factory in Thailand. Build quality is excellent, from the paint finish to the welds. There are some nice detail touches, including a stitched seat, brushed ali throttle body shrouds, logo'd chrome fuel cap, finned cylinder heads and dummy exhaust headers, to hide the catalyser.
The Street Twin offers superb value for money. Its retro rivals come in the shape of the more basic, but punchier Yamaha XSR700, the entry-level Harley Davidson Street 750 and the quirky-but-lovable Moto Guzzi V7 II Stone.
But the Triumph’s big rival is the Ducati Scrambler Icon. Both manage to pull off the neat trick of appealing to new and experienced riders alike, breezily mix classic cool with modern performance and technology and come with phonebook-thick clothing and accessory catalogues.
You get traction control and ABS as standard, as well as a Smiths-style white on black speedo, incorporating a multi-function digital display, an underseat USB socket and immobiliser. There are over 150 official Triumph accessories available, including heated grips, Vance and Hines 2-1 exhaust, a tail tidy, fly screen, handlebar grips…the list goes on. Triumph also offers three pre-prepared ‘Inspiration Kits’ to transform your Street Twin into a scrambler, flat-track and urban style. And of course there’s loads of old school Triumph-branded clothing to choose from.
