PERIODIC MAINTENANCE AND MINOR REPAIR6-246 Brand-new tires can have a rela-tively poor grip on certain roadsurfaces until they have been“broken in”. Therefore, it is ad-visable before doing any high-speed riding to ride conserva-tively for approximately 100 km(60 mi) after installing a new tire. The tires must be warmed upbefore a high-speed run. Always adjust the tire air pres-sure according to the operatingconditions.EAU21960Cast wheelsTo maximize the performance, durabil-ity, and safe operation of your vehicle,note the following points regarding thespecified wheels.
