At its core, motorcycle racing is a war of diminishing returns, where manufacturers, teams, and riders dive ever deeper into the details in search of an advantage.

The latest battleground is in rider coaching, with riders and now teams using rider coaches / spotters / observers / analysts to help riders identify where they are strongest and weakest.

Spotters and rider coaches have been around for a while. Wilco Zeelenberg started working with Jorge Lorenzo at Yamaha in 2010, and now has a similar role for Maverick Viñales. Jonathan Rea has worked with Keith Amor in WorldSBK, Amor also filming Rea to help him perfect his technique.

More recently, Valentino Rossi started working with former 250cc world champion Luca Cadalora, and has employed a rider coach for the VR46 Riders Academy, the talent pool of young Italian racers Rossi has taken under his wing.

Current Red Bull KTM MotoGP rider Bradley Smith was also a relatively early adopter. The Englishman has worked with former 500cc legend Randy Mamola since his entry into MotoGP, and is fulsome in his praise of the idea.

“I had Randy and I see that as a massive help just in terms of having eyes outside of the track,” Smith said. The Red Bull KTM spoke about rider coaches, their role and benefits, to a small group of journalists at the Sepang test.
