Tom's Tech Treasures: Studying The MotoGP Bikes At Phillip Island


Torque sensor on the Yamaha M1
Peter Bom: Like all current MotoGP engines, the Yamaha M1 has a torque sensor fitted to the drive shaft. By measuring the amount of torque delivered on the track, the manufacturer can validate their engine dyno torque maps and fine tune them on the track. Note that Yamaha don’t use them on Sunday, that’s when everything should be sorted out. Left of the sprocket is an ‘inside-out’ or inverted sprocket which the external starter motor slides into.

Peter Bom: This engine is tilted backwards for cleaning and maintenance. Note the (orange) caps that keep dirt out of the inlet / exhaust ports during transport and cleaning.
