Read our Triumph Speed 400 review covering the liquid-cooled DOHC engine, torque, WP suspension, fit and finish, specs, and price.

Neo-Retro Roadster #1 Ranked
TRIUMPH Speed 400

Constructed around a perimeter steel frame, the TRIUMPH Speed 400 is designed to provide confident stability at both highway speeds and city streets. Weighing 176 kg fully fueled, the bike handles quick transitions with ease, maintaining a planted feel on winding roads. Its robust hardware and high-quality body panels ensure long-term durability and premium street presence.

Maintenance Tip

Check engine oil levels every 1,000 km to prevent internal friction damage. Clean the drive chain periodically and lubricate it for optimal gear transmission.

Performance is driven by a highly efficient 40 PS engine optimized for strong mid-range torque. With a top speed rated at 145 km/h, this model offers more than enough performance for both highway and daily street riding. Telescopic front forks handle potholes smoothly, while the multi-speed transmission shifts cleanly.
