Of course, all internal combustion engines produce fumes as the result of the gasoline being consumed. However, in motorcycles, there is no protective enclosure such as the body of an automobile in which to ride, and the exhaust emissions swirl about the riders, who are able to detect the noxious odors.
Cars are generally contoured and quite streamlined, so that the air passes smoothly over and then behind the vehicle, generating only slight turbulence. The engine exhaust pipe is normally at the rear, and often directs the exhaust gases either down or to one side, to be swept back in the slipstream of passing air. There is a chance that some of the exhaust fumes will be caught up in the back-draft of the vehicle, and swirl about its back end. This is of no consequence, because the back window of the vehicle prevents fumes from being sucked into the passenger compartment. Vans and utility vehicles frequently carry warnings about travel with a rear gate open, because of the possibility of ingesting the vehicles own engine exhaust.
Motorcycles characteristically have a very un-aerodynamic profile, and are prone to much more burbling of the passing air. Like cars, some of the exhaust fumes from the motorcycle will be drawn into the turbulent zone immediately behind the rider's back. If the bike has a significantly tall windshield, the exhaust fumes from the engine will navigate further forward, being drawn into the turbulent back-draft zone just behind the windshield and around the rider's face.
To prove this, use a motorcycle with a tall windshield. Have a rider tape strings of about 20-30 cm each on opposite sides of the helmet's chin area. Then at 100 kph, observe how the strings are drawn forward in the airflow, toward the windshield. The exhaust fumes travel the same path from the back of the bike and swirl about the sheltered side of the windshield.
That is often why a motorcycle rider will sometimes smell of exhaust fumes.
