Built around Suzuki's custom - cruiser motorcycle platform, the 2021 Suzuki Intruder 155 utilizes a 155 cc (9.5 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 13.6 HP (9.9 kW) at 8,000 rpm while maximum torque reaches 13.8 Nm (10.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 87.7 HP per liter and a 2,000 rpm working window between peak torque (6,000 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 Intruder 155 measures 152 kg (335 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.18 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
