Don't let a tree branch end your ride or leave you stranded in the backcountry with no brakes.
Damage to the brake reservoir is a common failure on the XM and Gen4 Ski Doo. If the reservoir guard is damaged your sled will have no brakes, which is a dangerous position to be in.  The "original" Tree Huster is the solution to all these problems.  Mounts with existing stock bolts.
