Kingwelle Clutch Drag Bike Clutch - 4-disc for standard length crankshaft

The Kingwelle clutch, like the famous Kingwelle crankshafts, is a product that was born in racing. It is the final solution for all those who constantly demand everything from their extremely powerful engine. Be it in acceleration races or ambitious racetrack use. Engine power in the 40-70 hp range is transferred to the rear wheel with ease by the Kingwelle clutch.

Thanks to the use of extremely high-quality base materials, the clutch is virtually wear-free. However, all individual parts of the clutch are also available separately. The clutch kit also contains the clutch basket including the (so-called) primary repair kit (reinforced cover plate for the springs of the shock absorber).

FEATURES

• Real race clutch: controlled clutch engagement possible even at very high engine speeds

• Very high load capacity:

  • 4-disc clutch approx. 40-45PS (30-35Nm)

  • 5-plate clutch approx. 50-70PS (40-45Nm)

• Clutch springs are pre-tensioned (clutch can be installed when the vehicle is stationary)

• Latest version (2022): Cover plate screwed back on, no circlip = maximum stability even with hard springs

• All clutch types use the spring type of the PK XL2 clutches

AVAILABLE VARIANTS

• 4-discs for auxiliary shaft with standard length

SCOPE OF DELIVERY

• Clutch basket incl. reinforced cover plate for the shock absorber springs (4x M5x14 (10.9 Torx TX25)

• Clutch springs (XL thickness)

• Clutch linings with organic lining material (cork)

• Clutch spider (inner basket)

• Release bearing with needle bearings

• Spacer kit 1mm (only for 5-disc version)

RECOMMENDATIONS

• Oil filling quantity motor housing: 400ml (600ml for quattrinige housings)

• Oil type: Motul 7100 10W40

• Clutch cover: Vespa PK XL2 type (here the pressure mushroom presses centrally on the release bearing. In addition, the lever is geared = easier to pull)

• Do not pretension the lever so that the thrust bearing does not run under continuous load (risk of a defect in the release bearing which could cause metal parts to enter the gearbox)

• The clutch lever of the cover should be approx. 5-10 mm in front of a 90° angle to the Bowden cable of the clutch cable when not actuated. If the clutch lever is actuated, the clutch lever swivels back and forth over the 90° angle => largest lever movement => maximum release travel

• If spring stiffnesses are mixed, then only in a symmetrical arrangement. Spring stiffnesses, e.g. L or XL, vary from manufacturer to manufacturer - do not mix!
