Look where you want to go! Steer the bike with your eyes! You go where you look! How often have we motorcyclists heard these phrases?

Looking where you want to go obviously relates to vision, an important sense for everyday life; however when we introduce motorcycles, the importance of vision increases dramatically, not just as an essential tool for high performance riding and racing, but also for survival on the road.

The fact is most of us are damaging our vision, namely our peripheral vision, with our modern lifestyle of sitting in front of TV and computer screens. Compared to our ancestors, our visual field has narrowed dramatically.

If we get into the habit of looking directly at objects while restricting the awareness of our surrounding field of view, it’s comparable to not fully using other areas of our body.

For example if we routinely only bend our knee ten degrees, you could imagine this bad habit of restricted movement would ultimately lead to poor function, soreness, and long-term damage.

It’s safe to assume that our vision also follows the familiar “use it or lose it” rule that is evident in other areas of our body. In other words, if we only use one part of our visual field, the rest of our visual circuitry will begin to go inactive. So how important is peripheral vision to our riding and what can we do to increase our visual performance?

Asphalt & Rubber is please to bring you the motoDNA column, which will be written by our good friend Mark McVeigh, of the motoDNA Motorcycle Academy.

Mark is a former international 250cc racer, as well as a former MotoGP engineer. His unique experience and perspectives on motorcycle dynamics and racing will be a regular feature on A&R. Enjoy!

In these high tech days of electronic fuel injection, you would expect motorcycle throttle response to be smooth as. However many of the latest bikes have a snatchy and jerky throttle response; especially around town at low speeds — feeling more like a switch than a throttle.

This is not just plain annoying, but makes holding a steady throttle in corners and riding in town tricky, often becoming a bigger problem in wet and slippery conditions. On the track, life can be even more difficult when the bike is closer to the edge of the tire, due to higher lean angles.

The throttle controls not only acceleration and traction but has a large influence on our bikes handling including weight transfer, steering and stability. The throttle is also our connection to the rear tire. If it’s linear and smooth, this is reflected in our riding performance.

We expect modern bikes to have smooth and accurate throttle response; but in fact throttle response is worse these days compared to carburettors of old. Why? In one word – Emissions.
