good question yaar...didnt strike me...here is what i found out in bits and pieces.

They're called "thumpers" and with good reason. With one combustion event for every 720° of crankshaft rotation, big-bore (500cc and up) four-stroke single-cylinder motorcycles inherently produce the most vibration of any engine design. And when that cylinder fires, it's really an "event." Even so, there are pockets of hardcore thumper fans who wouldn't ride anything else. Their addiction rivals that of the diesel die-hards getting thrilled to the marrow by the sound of piston slap.

Single cylinder motorcycles, generically know in the U.S. as "thumpers", have been around for as long as there have been motorcycles, and there has always been a certain charm, a certain panache, a certain charisma surrounding them. Some say it is because of the ultimate simplicity of the engine, others are engagedby the unique sound emanating from them as they "thump, thump, thump" along Still others are enamored by the compact engine and light chassis that are part and parcel of a one-cylinder motorcycle.

in short

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.

do let me know about some more info.
