It is hard to overstate just how important the relationship between a motorcycle racer and his crew chief is. A rider must have complete confidence that his crew chief both understands what he needs from a motorcycle to go fast, and is capable of giving it to him.

A crew chief must be able to interpret the sometimes confusing and mixed signals from his rider, filter out the non-essential information, identify priorities from that which will offer the greatest gains, and assign the work to the rest of the crew in the garage.

There has to be complete trust between the two, or neither rider nor bike will achieve their full potential.

This was made all too apparent when I interviewed Ecstar Suzuki rider Aleix Espargaro and his crew chief Tom O’Kane for a story I wrote recently for the Dutch publication MOTOR Magazine, due out later this month.

One part of the interview which did not make it into the magazine was the relationship between Espargaro and O’Kane, and how they first started working together. However, it is a story which offers a fascinating insight into how a rider and their crew chief work together.
