4.8 DRIVE CHAIN '
Engine output is transmitted from the engine through ·
the clutch and the transmissio n where torque is con-
verted to th e chain drive. The chain used is a
RK420-B type high strength chain to withstand high
speed performance and high output . It is made end-
less by ,using only one joint clip and is housed within
the chain cases to prevent dust from ent ering,
preventing the rapid wear of the sprocket.
