PERIODIC MAINTENANCE 2-27 TIRES Inspect every 6 000 km (4 000 miles, 12 months). TIRE TREAD CONDITION Operating the motorcycle with excessively worn tires will decrease riding stability and consequently invite a dangerous situation. It is highly recommended to replace a tire when the remaining depth of tire tread reaches the following specification. 09900-20805: Tire depth gauge Tire tread depth: Service Limit: FRONT : 1.6 mm (0.06 in) REAR : 2.0 mm (0.08 in) TIRE PRESSURE If the tire pressure is too high or too low, steering will be adversely affected and tire wear will increase. Therefore, main- tain the correct tire pressure for good roadability and a longer tire life. Cold inflation tire pressure is as follows. Cold inflation tire pressure E 2 Solo riding: Front: 250 kPa (2.50 kgf/cm , 36 psi) 2 Rear: 290 kPa (2.90 kgf/cm , 42 psi) L 2 Dual riding: Front: 250 kPa (2.50 kgf/cm , 36 psi) 2 P Rear: 290 kPa (2.90 kgf/cm , 42 psi)  M The standard tire fitted on this motorcycle is 120/70 A ZR17 M/C (58 W) for the front and 190/50 ZR17 M/C (73 W) for the rear. The use of tires other than those spec- S ified may cause instability. It is highly recommended to use the specified tires. TIRE TYPE BRIDGESTONE (Front: BT014F SJ, Rear: BT014R J).........E-02, 19 (Front: BT014F J, Rear: BT014R E)...........Others STEERING Inspect initially at 1 000 km (600 miles, 2 months) and every 12 000 km (7 500 miles, 24 months) thereafter. The steering should be adjusted properly for smooth turning of the handlebars and safe operation. Overtighten steering pre- vents smooth turning of the handlebars and too loose steering will cause poor stability. Check that there is no play in the front fork. Support the motorcycle so that the front wheel is off the ground. With the wheel facing straight ahead, grasp the lower fork tubes near the axle and pull forward. If play is found, read- just the steering. (8-33)
