Chromed Chopper In The Custom Style

This gleaming beauty is what custom cruising all about.

You haven’t lived until you’ve ridden a big single-cylinder road bike. They’re flat out a blast to ride.

The Boulevard S40 takes that timeless single-cylinder design and adds a shot of advanced Suzuki technology to create a bike that combines exciting performance with rock-solid reliability.

One of the S40’s major attractions is its lightweight responsiveness – it’s great for cruising down the boulevard or beyond the city limits. Wherever you ride, one twist of the throttle rewards you with a blast of low-end and mid-range torque. And when you’re up to cruising speed, you’ll really appreciate the engine’s smooth performance.
