In 2005, Suzuki launched the Boulevard S40, a lightweight cruiser motorcycle that used to be called LS650 Savage between 1986 and 2004. In that period, the LS650 was the first cruiser manufactured by Suzuki, which remained basically unchanged with just some minor cosmetic changes and a transmission switch from a four-speed to a five-speed unit.
In 2005, Suzuki rebranded the motorcycle as the S40 Boulevard, retained the character of the old bike, and marketed it as an entry-level machine that was best suited for shorter riders and aimed to build a strong Boulevard family.
In the visual department, the bike featured a flat handlebar that provided a clean, sporty appearance, a sleek one-piece saddle, an attractive teardrop fuel tank with a speedometer mounted on top, and polished wire-spoked wheels for a classic look.
In addition, the model's look was enhanced by bright multi-reflector turn signals designed for high visibility and an attractive appearance and custom-style rear view mirrors like the larger Boulevard models.
As for performance, the 2005 Suzuki Boulevard S40 took its thrust from a 652cc four-stroke single-cylinder engine that delivered strong low-end power and torque and featured a black engine case with polished cylinder head fins. The bike delivered an output power of 31 hp at 5,400 rpm and 50 Nm (37 lb-ft) of torque available at 3,400 rpm.
The braking power was provided by a single 265 mm disc with a hydraulic caliper on the front and a rod-operated drum unit on the rear.
