51-mm (2.0-in) high-profile pattern drive track

For RX10M/RX10MS
This snowmobile is originally equipped with a 51-mm
(2.0-in) high-profile pattern drive track specifically for use
in deep snow riding conditions. 
Therefore, avoid prolonged operation on hard surfaces
such as ice, hard-packed snow, dirt, etc., to extend the
life of the track and slide runners.

CAUTION:

@ 

●

Only use in deep snow riding conditions. 

●

Operation on areas with light snowfall, ice, hard-
packed snow, dirt, or grass will result in rapid
wear or damage to the track and slide runners
from lack of snow which serves as a lubricant.
