India's RE Bullet Goes Global: Complete Breakdown of the New 650cc Model at EICMA

Milan, Italy—In a move that perfectly marries tradition with modernity, Indian motorcycle giant Royal Enfield officially unveiled the much-anticipated Bullet 650 at the EICMA 2025 motorcycle show in Milan. The launch marks the first time the company’s longest-running nameplate will be powered by the globally acclaimed Bullet 650 parallel-twin engine, promising a blend of timeless style and robust, accessible performance.

For decades, the Bullet has defined the essence of Indian motorcycling. The new Bullet 650 version honors that legacy while introducing a level of refinement and highway capability never before seen in the model.

The engine is the same tried-and-tested unit that powers the Interceptor 650, Continental GT 650, Super Meteor 650, and Classic 650, offering a superb blend of accessible power, refinement, and torque.

Key Technical Highlights

1. The 270 circ Firing Interval

Sound and Feel: The 270 crank is arguably the most crucial feature, as it gives the parallel-twin a unique, loping exhaust note that closely mimics the sound and pulse of a 90 V-twin or a classic single-cylinder “thump.” This ensures the bike retains the characteristic Royal Enfield feel while benefitting from a twin-cylinder configuration.
Balance: The engine uses a single gear-driven balancer shaft positioned ahead of the crankshaft to effectively quell vibrations, leading to the highly praised refinement of this platform.

2. Accessible Power Delivery

The engine is designed to be tractable and friendly. The relatively low power figure for a Bullet 650 twin (under 50 bhp means the power is delivered smoothly and progressively, making it an excellent highway cruiser and an easy-to-manage city bike.
Crucially, the peak torque of 52.3 Nm arrives early at just 5,650rpm, meaning you get a strong, usable surge of acceleration right in the mid-range—perfect for effortless overtaking.

3. Assist and Slipper Clutch

The assist function reduces the effort required to pull the clutch lever, which significantly improves comfort during city riding.
The slipper function prevents the rear wheel from hopping or locking up under aggressive downshifting, enhancing safety and stability.

Bullet vs. Classic: The Subtle Separation

While the Bullet 650 shares its chassis (steel tubular spine frame) and mechanicals (Showa suspension, dual-channel ABS) with the Classic 650, the models are distinguished by key stylistic choices:

Feature	Bullet 650	Classic 650
Seating	Single-piece, contoured bench seat	Sculpted, two-piece split seat design
Fenders	Simpler, more traditional box-style rear fender	More rounded, modern fender design
Stance	Slightly more upright and old-school riding triangle	Slightly more relaxed and cruiser-esque

Essentially, the Bullet 650 appeals to the rider seeking the most authentic, purist-retro aesthetic, while the Classic 650 caters to those who prefer a slightly more feature-rich, sculpted neo-retro look.

The combination of this modern, refined engine with the Bullet’s classic styling and upright stance delivers a machine that offers historic appeal with contemporary reliability and performance.
