Best 400cc Bikes in India 2026: The 400cc segment is ruling Indian roads these days, offering a unique blend of speed, style, and durability. If you’re looking for a premium roadster, the Royal Enfield Guerrilla 450 and the Triumph Speed 400 are neck-and-neck. On one hand, there’s the Royal Enfield’s muscular and rugged style, while on the other, there’s the Triumph’s British elegance and finishing. In this article, we’ll pit these two giants against each other and tell you which one offers the best value for your money, from engine power to features. Whether you’re looking to ride through narrow city streets or speed down the highway, this comparison will put your doubts to rest.
Engine and Performance
Royal Enfield has equipped the Guerrilla 450 with the same powerful ‘Sherpa’ engine as the Himalayan 450. This 452cc, liquid-cooled engine produces 40.02 PS of power and a remarkable 40 Nm of torque. The bike’s biggest advantage is that its torque is available at very low RPMs, eliminating the need to constantly change gears in traffic, and the bike accelerates like a rocket.

The Triumph Speed 400, meanwhile, has a 398.15cc engine that produces 40 PS of power and 37.5 Nm of torque. While the power output is nearly equal on paper, the Triumph’s engine is more refined and smoother. The Triumph’s lighter weight (179 kg) makes it feel very agile, making for a truly thrilling experience on long highways.
Design and Styling
In terms of design, both bikes are distinctly different. The Guerrilla 450 is a wide, muscular roadster. Its thick tires (160-section rear) give it excellent road grip and a “bully” look. Its compact design and high seating position make it popular among young people.
On the other hand, the Triumph Speed 400 is a modern-classic machine. Its finish level is so premium that it looks far more expensive than its price. Its excellent paint quality, gold-finished USD forks, and signature Triumph fuel tank give it a classic and elite look. If you prefer a bike that looks sober but delivers powerful performance, the Triumph is unmatched.
High-Tech Features
In terms of features, Royal Enfield has equipped the top variant of the Guerrilla with a 4-inch round TFT display, which offers powerful features like full Google Maps navigation, music controls, and phone connectivity. It also features two riding modes: “Eco” and “Performance,” which adjust power delivery based on your riding conditions.
The Triumph Speed 400 offers a powerful blend of analog and digital. It features ride-by-wire throttle, switchable traction control, and a torque-assist clutch. While navigation may be lacking, everything from the headlight to the taillight features a premium LED setup, making nighttime travel safer.
Riding Comfort and Handling
In terms of handling, the Triumph Speed 400’s 43mm USD (upside-down) forks and lightweight allow it to turn corners with great precision. It’s capable of navigating through heavy city traffic.
The Guerrilla 450 features telescopic forks and a monoshock rear suspension. Royal Enfield has tuned it to absorb rough roads and potholes with ease. Its wide tires give you tremendous confidence when cornering.
