Thumper (motorcycle)

Thumper (motorcycle)

A thumper is a motorcycle powered by a large capacity single-cylinder 4-stroke engine, so called due to the thump-thump-thump sound the engine makes.

Thumpers have good low-end power and are most often dirt-oriented bikes or dual sport motorcycles.

Some examples include the BMW F650, Kawasaki KLR, and Suzuki DR.

Harley Davidson converted the V-twin of its discontinued Sportster 1000 engine to make the 492cc (30.02 cubic inches) air-cooled power plant for its belt-driven Buell Blast model.
