Maximizing drive track life

Recommendations

Track tension

During initial break-in, the new drive track will tend to
stretch quickly as the track settles. Be sure to correct the
track tension and alignment frequently. (See pages 8-15–
8-17 for adjustment procedures.) A loose track can slip
(ratchet), derail or catch on suspension parts causing
severe damage. Do not overtighten the drive track, other-
wise it may increase the friction between the track and
the slide runners, resulting in the rapid wear of both com-
ponents. Also, this may put an excessive load on the sus-
pension components, resulting in component failure.

Marginal snow

The drive track and the slide runners are lubricated and
cooled by snow and water. To prevent the drive track and
slide runners from overheating, avoid sustained high-
speed usage in areas such as icy trails, frozen lakes and
rivers that have minimal snow coverage. An overheated
track will be weakened internally, which may cause fail-
ure or damage.

Off-trail riding

Avoid off-trail riding until there is sufficient snow cover-
age. It generally takes several feet of snow to provide a
good overall base to properly cover debris, such as
rocks, logs, etc. If snow coverage is not sufficient, stay on
trails to avoid impact damage to the drive track.

Studded track

In general, track life will be shortened when studs are
installed. Drilling stud holes into the drive track will cut
the internal fibers, which weakens the track. Avoid spin-
ning the drive track. Studs may catch on an object and
pull out of the track, leaving tears and damage around
the already weakened area. To minimize possible dam-
age, consult your stud manufacturer for installation and
stud pattern recommendations. 

Yamaha does not recommend track studding.
