Aftermarket parts, accessories, and modifications
While you may find aftermarket products similar in design and quality to genuine Yamaha Acces-
sories, recognize that some aftermarket accessories or modifications are not suitable because
of potential safety hazards to yo u or others. Installing aftermarket products or having other mod-
ifications performed to your Viking VI that chan ge any of the vehicle’s design or operation char-
acteristics can put you and others at greater risk of serious injury or death. You are responsible
for injuries related to changes in the vehicle.
Aftermarket tires and rims
The tires and rims that came with your Viking VI were designed to match the performance capa-
bilities and to provide the best combination of ha ndling, braking, and comfort. Other tires, rims,
sizes, and combinations may not be appropriate. Refer to page 8-44 for tire specifications and
