SPEED 400

The Triumph Speed 400 is a modern-classic roadster that blends timeless styling and approachable performance into a compact package. It’s designed to welcome new riders while delivering premium build quality, making every ride—from city streets to country lanes—effortlessly confident and fun.

Performance & Power Beneath the sculpted bodywork lies a liquid-cooled 398 cc single-cylinder engine, tuned to deliver 40 PS at 8,000 rpm and 37.5 Nm of torque at 6,500 rpm. The six-speed gearbox, aided by a torque-assist, slip-style wet clutch, ensures smooth power delivery and responsive acceleration—perfect for both relaxed cruising and nimble urban riding.
Control & Comfort With upside-down 43 mm Big Piston forks and a preload-adjustable rear monoshock, the Speed 400 strikes an ideal balance of comfort and control. It rides on 17-inch cast wheels wrapped in Metzeler Sportec M9RR tires, while its modest 790 mm seat height and neutral ergonomics deliver confidence to a wide range of riders.
Versatility & Style True to its “modern classic” lineage, the Speed 400 features minimalist lines, LED lighting, a brushed stainless silencer, and a hybrid spine frame. Its retro-inspired silhouette is paired with modern conveniences like ride-by-wire throttle, switchable traction control, analog-digital instruments, and Bosch dual-channel ABS—making it as stylish as it is practical.
