  • PANKL 6-speed gearbox → off-road specific ratios
  • No-dirt gear lever → prevents dirt build up for perfect control

DDS clutch 

The DDS (Dampened Diaphragm Steel) clutch system includes a single diaphragm steel pressure plate instead of traditional coil springs, making the clutch pull very light while also integrating a damping system for better traction and durability. The clutch basket is a single-piece CNC machined steel component that allows the use of thin steel liners and contributes to the compact design of the engine. The Magura hydraulic system ensures perfect action in all conditions. 

  • DDS clutch → compact with better action and improved durability
  • Magura hydraulic system → perfect clutch action
