The APTC ‘wet’ clutch gives a ‘slipper’ type action that prevents destabilizing of the rear-end under aggressive down-shifting and also gives the extra benefit of a super-light feel at the lever, a great benefit in stop-start city traffic or during longer journeys. The 21-plate oil-bath clutch (11 friction and 10 steel) represents a power-enhancing weight reduction over the ‘dry’ system as well as having a quieter operation and requiring less maintenance.
