Introducing The Expert: Greg McDonald
Marc Márquez is a lean angle magician on a MotoGP bike. The Repsol Honda rider regularly uses 60° or more to wrangle his RC213V through corners. The rest of us – and his rivals – stand in awe, and wonder how he manages to get away with it.
Yet he has also said he would rather not use so much lean angle. There are easier ways around the corners, but with the 2019 Honda RC213V, using a lot of lean angle is the only way Márquez can maintain his competitiveness.
Why does he need so much lean angle? Keen to find an explanation for this I got in touch with Australian chassis expert Greg McDonald. McDonald worked as a GP and Superbike ‘insider’ for many years, but was previously reluctant to talk about the work he did for a string of factory teams, for commercial reasons.
