The mid-capacity modern classic segment is heating up, and two of the most exciting contenders are a British icon reimagined and an Indian powerhouse ready to pounce. On one side, we have the polished Triumph Speed 400, a perfect canvas for a custom Tracker build. On the other, the rugged and highly anticipated Royal Enfield Guerrilla 450.
While one is a custom concept and the other is a factory-fresh roadster, they are destined to compete for the hearts and wallets of riders looking for style, performance, and character. Let's break down how these two machines stack up.
The core difference between these two motorcycles lies in their engine philosophy.
The Triumph Speed 400 is powered by a modern 398cc, liquid-cooled, single-cylinder "TR-series" engine. This is a gem of engineering, known for its smooth, free-revving nature. It delivers its power in a linear, predictable way, feeling eager to climb the rev range. With around 40 horsepower, it’s lively and potent, offering a ride that feels refined and sophisticated. It’s the kind of engine that rewards a spirited rider, feeling more like a scaled-down European performance bike than a traditional thumper.
The Royal Enfield Guerrilla 450 borrows its heart from the acclaimed Himalayan 450—the 452cc, liquid-cooled "Sherpa" engine. This motor is all about robust, accessible torque. While it also produces around 40 horsepower, its character is completely different. It delivers a strong, grunty punch in the low to mid-range, making it incredibly tractable and effortless for city riding and quick overtakes. It’s an engine with a palpable character, prioritizing real-world usability over high-rpm thrills.
Design and Ergonomics: British Polish vs. Rugged Utilitarianism
This is where the "Tracker" concept comes into play for the Triumph.
As a Triumph Speed 400 Tracker, you start with the base bike’s impeccable fit and finish. The Speed 400 boasts clean lines, a beautifully sculpted tank, and premium details. To transform it into a tracker, you’d add wider, flatter handlebars, knobby or dual-sport tires, a minimalist tail section, and perhaps a custom flat seat. The result is an aggressive, lean, and stylish urban assault vehicle that looks custom-built from the showroom floor.
The Royal Enfield Guerrilla 450, based on spy shots and industry buzz, presents a more rugged, neo-retro roadster aesthetic straight from the factory. It features a muscular teardrop tank, a classic round headlamp, and a purposeful, no-nonsense stance. It looks less polished and more utilitarian than the Triumph, designed to look tough and ready for any road, paved or not. Its ergonomics are expected to be more upright and comfortable, making it a natural fit for longer journeys.
Technology and Features
Both bikes are thoroughly modern, but their tech suites have different priorities.
The Triumph Speed 400 comes loaded with features that enhance its performance credentials. It includes a ride-by-wire throttle, switchable traction control, a torque-assist slipper clutch, and full LED lighting. The part-analog, part-digital instrument cluster is clean and provides all the essential information. The focus here is on rider aids and safety.
The Royal Enfield Guerrilla 450 is also expected to feature a ride-by-wire throttle and switchable ABS. However, its standout feature will likely be the option for Royal Enfield’s Tripper navigation system. Whether it’s the simple turn-by-turn unit or the full-map display from the Himalayan, this focus on integrated navigation gives it a distinct advantage for explorers and tourers.
The Verdict: Who Should Buy Which?
The choice between these two incredible machines comes down to your personal style and riding priorities.
