saw the inside of a ramp style slipper the other day, now I was led to believe that the surflex slippers on the tornado's are a endless screw/ thread type design, can anyone explain how these work? or does anyone have a pic of the actuall slipper mechanism.
Yes, I'm retarded ;)

Its a ramp type mate.I think there are 4 ramps on the boss that is in the centre of the hub and it lifts a plate that in turn reduces the spring pressure on the plates IYSWIM.

is that with ball bearings?

see a surflex description below ive lifted from the web.

Complete Lightweight Slipper Clutch by Surflex helps prevent rear wheel lock up on deceleration. Lighter weight improves throttle response and reduces rotating mass. This clutch is preferred by many track riders over many more expensive models due to its smooth, low effort engagement and long wear characteristics. It is also requires the least amount of maintenance.

The Surflex all Aluminum billet anti-slipper clutch is the most complete of all units. The Surflex is pre-assembled with all hard anodized billet aluminum components: clutch drum, top pressure plate, alum basket, spring bolts, springs and alloy spring retainers. It even includes hardware for mounting the basket and an installed throw out bearing. Pre fitted Surflex Aluminum friction discs are included for extra weight savings, quiet function and longer basket life. Light springs are included that reduces the lever effort by over 50%. The clutch comes pre-assembled for ease of installation.

Dimensions: 8.0 in. x 6.0 in. x 6.0 in.

Surflex uses a patented endless screw design that does not require any maintainance. It does not use ball bearings that need constant cleaning and lubrication.
Quality Surflex carbon/aluminum clutch friction discs are included and pre-fitted to the basket ($220 value). The tight fitting Surflex fricion discs are very quiet and last longer.

All billet hard anodized aluminum basket, drum and pressure plate save up to 5 pounds of rotating weight when used with the aluminum discs.

Tested on 180HP Corsa bikes, this slipper will stand up to the punishment of racing or hard canyon riding.

Excellent value. Comparable to other systems which cost over $2000 complete. SALE LIMITED TO STOCK ON HAND. Imported from Italy. Fits all dry clutch Ducatis except the 1098 series. For 1098 slipper cluch see: "JTR Corse 1098 Slipper Clutch w/ plates ".

Note: This street/track slipper is the personal favorite of our mechanics and the guys in the shop. We use the Surflex on most of our project bikes. This version is highly recomended for most applications due to its low lever effort, llow maintenance and smooth engagement. We recomend the RACE Surflex for riders that have constant hard launches.

more twists

maybe the LE used the street version, and Tornado's and RS's use the race version?

The Surflex "Race" Slipper Clutch w/ Plates does not have any ramps or ball bearings. It uses an endless screw design that releases the plate on downshifts. The Surflex race slipper has a recessed spring design on the pressure plate. The clutch pull is similar to other slipper clutches because it uses heavier OEM type springs designed for hard race launches


The street and track day oriented Surflex "Slipper" Clutch w/ Plates is well known for its easy clutch pull that feels like a cable clutch..it uses lighter clutch springs than OEM.


Our Motowheels Slipper Clutch w/ Friction plates have ball bearings/ramps like most other slipper clutches and feature Surflex friction plates. The complete Motowheels slipper retails for several hundred dollars less than the complete Surflex units
