At the heart of the 2025 Royal Enfield Guerrilla 450 Roadster motorcycle, Royal utilizes a 452 cc liquid cooled-cooled four stroke, single cylinder, dohc layout. In factory specification, peak output is rated at 40 HP (29.4 kW) at 8,000 rpm while maximum torque reaches 40 Nm at 5,500 rpm, transferring power to the rear wheel through a 6 speed gearbox and chain final drive. With a specific output of 88.5 HP per liter and a 2,500 rpm working window between peak torque (5,500 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Enfield Guerrilla 450 Roadster measures 185 kg (408 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.63 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
