PERIODIC MAINTENANCE AND ADJUSTMENT EWA10521 EWA10461 EAU21962 WARNING ● WARNING The front and rear tires should be of the same make and design, otherwise the handling characteristics of the vehicle may be different, which could lead to an accident. After extensive tests, only the tires listed below have been approved for this model by Yamaha Motor Co., Ltd. Front tire: Size: 120/70-21M/C 62H Manufacturer/model: METZELER/ME880 MARATHON Rear tire: Size: 210/40R18M/C 73H Manufacturer/model: METZELER/ME880 MARATHON Cast wheels To maximize the performance, durability, and safe operation of your vehicle, note the following points regarding the specified wheels. ● The wheel rims should be checked for cracks, bends, warpage or other damage before each ride. If any damage is found, have a Yamaha dealer replace the wheel. Do not attempt even the smallest repair to the wheel. A deformed or cracked wheel must be replaced. ● The wheel should be balanced whenever either the tire or wheel has been changed or replaced. An unbalanced wheel can result in poor performance, adverse handling characteristics, and a shortened tire life. ● It is dangerous to ride with a worn-out tire. When a tire tread begins to show lines, have a Yamaha dealer replace the tire immediately. Brakes, tires and related wheel parts replacement should also be left to a Yamaha dealer. Ride at moderate speeds after changing a tire since the tire surface must first be "broken in" for it to develop its optimal characteristics. 7 Tire information This motorcycle is equipped with tubeless tires, tire air valves and cast wheels. Tires age, even if they have not been used or have only been used occasionally. Cracking of the tread and sidewall rubber, sometimes accompanied by carcass deformation, is an evidence of ageing. Old and aged tires shall be checked by tire specialists to ascertain their suitability for further use. 7-16
