MotoGP » Yamaha to use seamless gearbox at Misano


As I understand it the system is neither torque converters or double clutched. They are completely mechanical systems using ratchet and pawls that mesh the gears above and below the one that is engaged at the same time on a single shaft and clutch. This is very complicated and I expect is difficult to make reliable with the power involved. Double clutch transmissions are actually less complicated but require electronics to control the two clutches (as if there was only one) that the rules do not allow. These systems use two shafts, one inside the other with a clutch each. Gears 1,3,5 on one shaft, 2,4,6 on the other. The only electronic part is the quick shifter system that cuts the spark plugs for a few milliseconds when the shifter is depressed. This has been standard for a long time.
