Motorcycle Cruiser

Big single-cylinder motorcycles are timeless, and the 2011 Suzuki Boulevard S40 keeps this tradition alive.

The S40 offers an optimal blend of low- and mid-range torque in a design that has proven reliability. This motorcycle keeps it simple, allowing riders the simple pleasure of motorcycling.

For 2011, the Boulevard S40 is available in two new color schemes: Pearl Mirage White/Metallic Veil Silver and Metallic Fox Orange/Glass Sparkle Black.

Chassis Features:
 Hydraulic front disc brake and drum-type rear brake provide strong, reliable braking performance.
 A wide 15" rear tire and slim 19" front tire provides a classic cruiser look.
 Polished spoke wheels provide a classic look like larger cruiser models and a polished upper fork bracket features an attractive and durable clear coat finish.
 A sleek, one-piece saddle adds to the Boulevard S40's already streamlined appearance. The low seat height (only 27.6 inches) is great for smaller or entry-level riders.
 The Boulevard S40 comes with an attractive tear drop-shaped fuel tank (2.8 gal capacity) with flush-mounted speedometer.
 Custom flat handlebar design provides a clean, sporty appearance, while custom-style rear view mirrors provide an attractive appearance (similar to the larger Boulevard models).
 The rear reflector is integrated with the taillight for a clean, finished appearance to the rear section of the bike.

Engine Features:
 The Boulevard S40 features a 652cc, SOHC, single-cylinder four-stroke engine with TSCC (Twin Swirl Combustion Chambers) cylinder head and high mass crankshaft that produces strong low-end power and torque.
 A black engine case and cylinder with polished cylinder head fins offers a finished appearance. Zinc-plated cylinder mounting bolts (a high quality plated finish that is corrosion resistant) blends with the black engine color for a more detailed appearance.
 An electric starter with automatic decompression system provides quick, easy engine starting.
 The Boulevard S40 is equipped with a precision electronic ignition system with maintenance-free battery.

Transmission Features:
 A 5-speed transmission with low-maintenance belt-drive system. The drive belt is quiet, durable, simple to adjust and clean.
