B) Before every ride: mechanical safety checks
(see section 3.5)
C) After every long or hard ride; if the bike has
been exposed to water or grit; or at least
every 150 km or 100 miles:
• Clean the bike, incl. chain ring and rear
wheel sprocket.
• Clean and lightly oil the chain.
• Wipe off excess oil.
Lubrication is a function of climate. Talk to
your dealer about the best lubricants and
the recommended lubrication frequency for
your area.
D) After every long or hard ride or after 10 to 20
hours of riding:
• Squeeze and hold the front brake and rock
the bike forward and back. If you feel a
clanking or looseness with each forward
or backward movement of the bike, you
may have a loose headset. Have your
dealer check it.
• Lift the front wheel off the ground and turn
the handlebar to the left and to the right a
few times. If you feel any binding or
roughness in the steering, you may have a
tight headset or the headset may need to
have grease added to the ball bearings.
Please ask your dealer to check it.
• Hold one pedal and rock it back and forth
across the centreline of the bike; then do
the same with the other pedal. If anything
feels loose, please ask your dealer to
check it.
• Take a look at the brake shoes. If they're
starting to look worn or are not hitting the
wheel rim squarely, have the dealer adjust
or replace them.
• Check the control cables and cable
housings for any rust, kinks, or fraying. If
you notice any of these problems or if your
brakes and/or shifter are not functioning
smoothly, ask your dealer to check and
replace the cables if necessary.
• Squeeze spokes in adjoining pairs on
either side of each wheel between your
thumb and index finger. They should all
have about the same "tension". If any feel
loose, have your dealer check the wheel
for spoke tension and trueness.
• Check the frame (particularly in the area
around all weld joints), the handlebar, the
stem and the seat post for any deep
scratches, cracks or discoloration. These
are signs of stress-related fatigue and
indicate that a part is at the end of its
useful life and needs to be replaced.
• Check to make sure that all parts and
accessories are still secure, and tighten
any which are not.
E) As required: If either brake lever fails the
mechanical safety checks (see section 3.5),
restore brake lever travel by turning the
brake cable adjusting barrel anti-clockwise,
then lock the adjustment in by turning the
barrel's lock nut clockwise as far as it will
go. If the lever still fails the mechanical
safety checks, have your dealer check the
brakes.
F) If the bike won't shift smoothly and quietly
from gear to gear: the gear mechanism may
be out of adjustment. The cause may be as
simple as a stretched control cable, in which
case you can compensate by rotating the
shift cable adjusting barrel.
Turn the gear shifter on the handlebar to
select the 2nd gear.
The yellow coloured part must be between
the 2 yellow lines on the window (rear wheel
axle, RH side). See fig. 26.
If this is not the case, adjust the shift cable
adjusting barrel near the rear wheel until the
position of the yellow painted arm is correct.
Lock the adjustment by turning the barrel's
lock nut. Try shifting again. If turning the
cable adjusting barrel does not cure the
problem, see your dealer.

G) Every 50 hours of riding: Take your bike to
your dealer for a check-up.
