2017 Triumph Street Twin 900: Modern Classic Character

The 2017 Triumph Street Twin blends timeless British motorcycle styling with approachable performance and useful modern technology. As part of Triumph’s Bonneville family, it delivers the familiar character of a parallel-twin engine in a manageable roadster designed for commuting, relaxed weekend rides and everyday urban use.

Responsive High-Torque Twin

Power comes from Triumph’s 900 cc liquid-cooled, eight-valve parallel-twin engine with a 270-degree firing interval. Tuned for strong low-end torque, it provides smooth, flexible response without requiring constant gear changes. A five-speed transmission and torque-assist clutch contribute to easy operation in traffic and a relaxed feel on open roads.

Ride-by-wire throttle control manages power delivery while supporting rider aids such as switchable traction control. The engine’s discreet liquid-cooling system preserves the classic appearance, while fuel injection offers dependable starting and consistent performance.

Key Street Twin Highlights

• 900 cc parallel twin: Broad, accessible torque suits city riding, secondary highways and casual touring.
• Anti-lock braking: Standard ABS adds reassurance during sudden or low-grip braking situations.
• Switchable traction control: Helps manage rear-wheel slip while allowing rider control over the system.
• Torque-assist clutch: Reduces clutch-lever effort for greater comfort in stop-and-go traffic.
• Low seat height: The 750 mm seat supports confident footing and easy low-speed manoeuvring.
• Cast-aluminum wheels: An 18-inch front and 17-inch rear balance classic proportions with responsive road handling.

Designed for Everyday Roads

An upright riding position, wide handlebar and low centre of gravity make the Street Twin welcoming for a broad range of riders. Its tubular steel frame and twin rear shocks retain traditional Bonneville visual cues, while the front disc with a two-piston floating caliper and rear disc provide practical stopping performance.

A compact single-dial instrument display includes an analogue speedometer and multifunction LCD. The Street Twin is well suited to riders who value classic design but still want contemporary braking, engine management and day-to-day usability in a straightforward middleweight motorcycle.
