 Wheels and tyres
Checking tyre tread depth
Your motorcycle's handling and grip can be impaired even before the tyres wear
to the minimum tyre tread depth permitted by law.
Have the tyres changed in good time before they wear to the minimum
permissible tread depth.
Make sure the ground is level and firm and place the motorcycle on its stand.
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.
 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. Check the wheel alignment, re-tighten
adjuster bolts, adjuster lock nuts and rear wheel nut.
