CCM Spitfire 2020 Series Owner's Manual page 21

Measure the tyre tread depth in the main tread
grooves with wear marks.
Tyres have wear indicators integrated into the
main tread grooves. The tyre is worn out when the
tyre tread has worn down to the level of the
marks. The locations of the marks are indicated
on the edge of the tyre, e.g. by the letters TI, TWI
or by an arrow.
If the tyre tread is worn to minimum: replace tyre
or tyres, as applicable.
Checking wheel rims
Make sure the ground is level and firm and place
the motorcycle on its stand.
Visually inspect the rims for defects.
Have damaged rims checked and, if necessary,
replaced by a specialist workshop.
Checking spokes
Make sure the ground is level and firm and place
the motorcycle on its stand.
Draw the handle of a screwdriver or a similar
instrument across the spokes and listen to the
notes of the individual spokes.
If the notes vary:
Have the spokes checked by a specialist
workshop.
• Drive Chain
Lubricating chain
Dirt, dust and inadequate lubrication will result in
accelerated wear and significantly shorten the
drive chain's useful life.
Clean and lubricate the drive chain at regular
intervals.
Lubricate the drive chain AT LEAST every 500
miles.
Lubricate the chain more frequently if the
motorcycle is ridden in wet, dusty or dirty
conditions.
Clean the drive chain with a suitable cleaning
product, dry it and apply chain lubricant.
Wipe off excess lubricant.
Checking chain slack
Excessive chain slack will cause increased chain
noise and increased chain wear. Excessive chain
slack may also result in damage to the swingarm
and other components.
Recommended chain slack (1) is 20mm.
To adjust chain slack, loosen the rear wheel nut
and use the chain adjuster bolts to achieve
recommended chain slack. Re-tighten adjuster
bolts, adjuster lock nuts and rear wheel nut.
