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.

"Although it feels a bit out of breath at 65 mph, the S40 doesn’t shake with anything like the ferocity of an unbalanced 650cc single. If you don’t plan to cruise at 75 mph, there is enough power." – motorcyclecruiser

"The S40 is a 650cc air-cooled single-cylinder 4-stroke. It is an updated version of the old Savage. I was surprised at how smooth the single cylinder engine ran, even when pressed hard. The power was more than ample to scoot away from stop lights and traffic, and it will cruise comfortably at 70 mph" – motorcycle-usa

"If there is any bike that deserves recognition for minimalist perfection, it is the Suzuki Boulevard S40. The bike does what a motorcyle purist wants, and does it well. It can handle highway speeds with ease, and serves a fantastic daily ride for commuting. Fuel Economy is in the 46-52 MPG range." – essforty
