The Savage utilizes Suzuki's "Big Single" power plant, a ~30 horsepower, 40 cubic inch (652 cc), four-stroke, single cylinder, air cooled, single overhead cam engine. Single cylinder engines like the one used in this motorcycle are sometimes affectionately referred to as a one-lunger or thumper. This engine is considered to be a geared-for-in-town performance torquer style of motor, delivering good performance at moderate revs compared to most Japanese motorcycle engines.
The Savage was produced from 1986 to 2004. For 2005 it was renamed to the Boulevard S40 and production continues to this day. Apart from some slight cosmetic changes, the LS650 remained unchanged until 1995 when it undertook the most noticeable change going from 4 to 5 speeds. The LS650 is a good motorcycle for beginners due to its easy handling and light weight at 352;lbs. But its classic design and ease of maintenance also make it a "preferred choice" for older, more experienced riders. At an overall height of 45 inches, it has been considered a bike for people under 6 feet tall, but riders taller than 6 feet can be equally comfortable with the addition of forward controls.
