Motorcycles excite all of the senses. When it comes to sight, they can be beautiful or ugly — and even in between.

In regards to smell, they emit a heady scent of oil, gasoline and rubber — and heat has a way of intensifying the effect. Touch? There are many different textures on a motorcycle, from cast aluminum to welded steel — and of course there's the sensory overload of actually riding, and that's where taste could enter the picture. And aurally, motorcycle engines produce their own distinct music, whether a tiny 2-stroke single-cylinder or a large 4-stroke multi-cylinder.

Enthusiast Mark Cummings appreciates everything about motorcycles, but in the late 1980s it was the sound of an MV Agusta 750S America that sent a chill down his spine.



Growing up in Fort Worth, Texas, Mark started off riding a Honda Mini Trail. Larger bikes followed, and by the time he entered his first year of college he'd saved enough money to buy a used BMW R90/6 from the late Perry Bushong.

Perry was a master mechanic and sidecar enthusiast who, starting in the early 1970s, bought, sold, traded and repaired BMWs and many other exotic European machines, including MV Agustas. Through the late 1970s and into the 1980s, Mark haunted Perry's shop, BMW of Fort Worth. It was a place that fueled Mark's motorcycling dreams.

Why are Italians fixated with giant wet sump engines? Sure, it sounded neat, but try and adjust the valves. That huge sand cast engine would look better in a crab boat thumping along the Amalfi coast.

Nice article--but no video with the sound the bike makes--which was part of the headline. Just a thought.
