Motorcycles are more than just two wheels and an engine. So, to point out the basic parts of a motorcycle, we have here a 2013 Triumph Street Triple R, all new for this year. You can see that it does have two wheels and an engine, but there are a lot other things that go into it.
Like, the handlebars, where the majority of your controls are placed. We have your throttle and front brake over here. On the far side, we have your clutch lever. We have several electrical components, secondary controls, your gauges, headlights. We have your foot controls, your rear break is on the right side. We have your gear selector over here on the left. Passenger accommodations, foot rests, passenger or also referred to as the pillion seat, the operator's, rider's seat. In front of that, you straddle the gas tank, filled up through the gas cap here up top.
Modern motorcycles vary. However, components like the exhaust system on this bike, the trends are going towards placing the weight of the motorcycle as low as possible. So on this Triumph, the exhaust is mounted under the engine, but traditionally you might see it placed differently, up high on the right side. Some sporting motorcycles for ground clearance also place the exhaust system underneath the seat.
Your motorcycle may vary, but that is the general components of your motorcycle.
