What is on the Original Friction Plates...

Clutch Friction material basics.

Friction plates are graded according to the grip they provide, this measure is called 'The Coefficient of Friction' and it gives an indication of the slip resistance of a surface. The coefficient of friction value is a calculation expressed as a number between 0.0 and 1.0. The closer the number is to 1.0 the greater the resistance to slip provided (ie: higher numbers give more grip). Surfaces with high coefficients of friction (COF 0.6 or higher) have greater texture, provide more grip and last longer. ...and grip and long life is what you want from Clutch Friction Plates.

What's in there now.

The standard material on most Japanese and some late Model European wet clutches is made of a rubber impregnated cork (co efficient of about 0.03). This rubber impregnated cork material is prone to glazing under extreme and hard riding conditions and once glazed, it will slip until the clutch is replaced. This slipping will cause excess heat which will further damage the material as cork is not known to handle heat well and the cork may de-laminate from the plate it is bonded to. Heat will also cause hot spots and warping of the intermediate (steel drive plates). Not to mention the damage the heat does to the oil the clutch and gearbox runs in.

Now choose the Friction material for your type of riding...

Option 1. Have your Wet Clutch Friction Plates re surfaced with Kevlar by Mr. Clutch.

Kevlar blended composite Plates are goldy green in colour, it is the same type of material used in bulletproof vests. It is very strong and has a co efficient of about 0.13 (same as sintered bronze). The Kevlar used is designed to run only in oil. If Kevlar is pushed hard and does happen to slip it will not glaze, it will form a small amount of carbonization and wear through so adjustment of the Clutch Pack thickness is an option. This will increase the working life compared to the rubber impregnated cork. Kevlar will usually handle temperatures of up to 300deg C and the resin used to bond the friction material to the plate has a sheer point of 350deg C. Kevlar resurfaced Clutch Plates have been used in drag racing / road racing / street riding and off road use with great success.

Option 2. Have your Wet Clutch Friction Plates re surfaced with Carbon by Mr. Clutch.

Carbon fibre blended composite Plates are black in color and have similar technical qualities and co efficient to Kevlar. Carbon friction material is suited to a more high energy application, so it is mainly used where high RPM or sustained periods are experienced. Although Carbon can run in a dry clutch, it is only recommended in low hp applications like vintage bike dry clutches. Carbon is mostly used in very high RPM motors and by riders and teams in long races, however it is dearer than Kevlar and doesn't last as long.

Simply send us your old friction plates and we will resurface them to competition specifications. It is simple, affordable and it works.

Option 3. New Sintered Brass Clutch Packs for Ducati.

Sintered Bronze Plates are goldish in colour, Sintered Brass is duarable and very strong. It has a co efficient of about 0.13. The Sintered material used is designed for higher demand Dry Clutches. Ideal for all Dry Clutch Ducati Motorcycles, Sintered Clutch Plates have been used in drag racing / road racing and street riding with great success. Ducati Clutches are high performance and agressive with Clutch Plates and the Clutch Basket, it wears the friction Plate 'dogs' badly. The solution is clear, now owners can get durable long life Clutch Packs (8 new Sintered Friction and 10 new Steels) from Mr. Clutch. Also for Ducati is a special Starter Plate to aid race starts.
