Vehicle Information
Suzuki Boulevard S40 Motorcycle - Street (2005-2019)
The Suzuki Boulevard S40, produced from 2005 to 2019, is a classic cruiser motorcycle known for its accessible single-cylinder, air-cooled 652 cc engine. It maintained a consistent core design throughout these model years, largely carrying over from its predecessor, the Suzuki LS650 Savage. The engine, featuring a Single Overhead Camshaft (SOHC) and a Mikuni BS40 carburetor, delivered approximately 30-31 hp. During its production run, the S40 was primarily offered as a single model, with variations limited to different color schemes and minor aesthetic updates rather than distinct trims with varying mechanical specifications. The most significant change occurred in 2005 when the LS650 Savage was rebranded as the Boulevard S40, and the transmission was updated from a four-speed to a five-speed unit for smoother shifts. Beyond this, the engine and chassis remained largely unchanged, continuing to use a carbureted fuel system until its discontinuation in 2019. Q: How do I find parts specific to my Suzuki Boulevard S40?
