WARNING

Incorrect loading, improper installation or use of accessories, or modification of your 
motorcycle may result in an unsafe riding condition. Before you ride the motorcycle, 
make sure that the motorcycle is not overloaded and that you have followed these 
instructions.

NOTE

CFMOTO parts and accessories have been specially designed for use on CFMOTO 
motorcycles. We strongly recommend that all parts and accessories you use are 
genuine CFMOTO components.

Always use CFMOTO genuine parts and accessories. Non-genuine parts or accessories, improper

 installation or use of accessories, or motorcycle modification, will void motorcycle warranty, can 

negatively affect performance and can even be illegal. In selecting and using parts or accessories, 

and in loading motorcycle, you are personally responsible for your own safety and the safety of 

person involved

.

Because a motorcycle is sensitive to changes in weight and aerodynamic forces, you must take 
extreme care in carrying cargoes, passengers and/or in fitting of additional accessories.

LOAD AND ACCESSORIES INFORMATION

Important information before ride

1

、

Any driver and/or passenger should be completely familiar with motorcycle operation. The pas-

     senger can affect control of motorcycle by improper positioning during turning corner or sudden 

     movements. So it

'

s important for passenger to sit still while the motorcycle is in motion and not

 interfere with the

 

operation of motorcycle. Do not carry animals on the motorcycle.

2

、

You should instruct any passenger before riding to keep his/her feet on the passenger footpegs

     and hold on the driver or grab rail

.

Do not carry a passenger unless he or she is tall enough to reach

 

     footpegs and footpegs are available

.

3

、

All baggage should be carried as low as possible to reduce the effect on the motorcycle gravity.

     Baggage weight should also be distributed equally on both sides of motorcycle. Avoid carrying

     baggage that extends beyond the rear of the motorcycle.

4

、

Baggage should be securely attached. Make sure that baggage will not move around while you're

     riding. Recheck baggage security as often as possible and adjust if necessary.

5

、

Do not carry heavy or bulky items on a luggage rack. They are designed for light items, and 

     overloading can affect handling due to changes of weight distribution and aerodynamic forces.

6

、

Do not install accessories or carry baggage that impairs the performance of motorcycle. Make

     sure that you have not adversely affected any lighting components, road clearance, banking

     capability (i.e., lean angle), control operation, wheel travel, front fork movement, or any other 

     aspect of motorcycle

'

s operation.
