EBC CLUTCH KITS FOR STREET AND DIRT BIKES
EBC Street bike clutches for street bike
Standard - CK Series
Almost identical to original equipment clutch plates, the CK series are a cork based product impregnated with
aluminum particles to increase wear life and heat resistance. Material is highly compressed to avoid swell and
clutch drag and is an ideal general purpose replacement material for all grades and sizes of motorcycles. Kit
includes a complete “engine set” of friction plates only.
Upgrade - SRC Kevlar Series (Race/Sport)
A Kevlar paper lined plate set complete with heavy-duty clutch springs, (for bikes fitted with diaphragm type
springs, we cannot supply a heavy duty spring kit), the SRC kit is
EBC Dirt bike clutches for off-road bike

Upgrade - DRC Kevlar Series
EBC’s number 1 selling product for motocross sport use, the DRC full
kit includes heavy-duty aluminum impregnated cork based plates, 10%
upgrade clutch springs and steel intermediate driven plates. The steel
intermediate plates outlast stock alloy units and prevent muddying of
the oil, maintaining stack height longer and with slightly heavier weight
give an improved fly wheel effect on smaller engines. The CK series
plates within the DRC set include the new “wide ear” construction lined
plates which prevent “dogging” of the clutch basket, see sketch above.
Race - EP Kevlar Series
(See application information below) A complete kit with Kevlar lined
friction plates, steel separator plates and heavy-duty clutch springs.
The EP kit is a heavy duty hightemperature resistant clutch, suitable
for sport/race use and Moto-X . Since 1998 some models (denoted by
‘S’ suffix after part number) have been upgraded to have lined plates
using a steel carrier body which should be located closest to the inboard
or engine side of the clutch and compensate for overload fractures which
happen when the clutch basket wears or “spreads”.
CSK Spring Kits
Always fit new springs which get tired after miles of heat and use.EBC
spring kits are 10% stiffer than standard and are sold in engine sets.
As stated in general fitting/safety instructions, advise customers that
lever will feel slightly heavier when uprating springs, and to test ride to
acquaint themselves with the change in control.
DIAPHRAGM CLUTCH SPRINGS
EBC SRK clutch kits, shown on the following page which include the diaphragm spring range.
The picture opposite shows a typical aftermarket billet clutch and how the assembly looks. It is essential when
replacing the diaphragm spring that the anti-scuff plate is in good condition. This is a rather flimsy steel
pressing and can become bent or distorted in which case it must be replaced, this is a genuine part available
from your main dealer only.
