SECTION 07 - 2005 MX Z X 440 INFORMATION
MMC2005-001_07A.FM
07-3
TRACK & TRACTION
The track used on the 2005 MX Z X 440 REV is
similar to past years but with some improve-
ments. The lug pattern and height are the same
as the 2004 MX Z X 440 REV with the lug height
being 1¾" on the outside belts and 15/8" on the
inside belt. Lug profile uses a "cupped" design to
ensure maximum traction. Major improvements
involve the increased number of track clips in-
stalled. For this year, there are clips placed on ev-
ery bar instead of every 3rd bar as in the past. This
increases track efficiency and reduces torsional
load on the drive sprockets and shaft. ISR rules
prohibit an optional track in the stock 440 class this
year. Track changes may be done in the Mod
Classes, the recommended track is similar to the
stock 440 track except it uses 1 ¾" lug all the way
across. The recommended track part number is
504 152 168.
Most aftermarket traction companies offer prod-
ucts specifically for this type of track. Contact the
traction companies for recommended traction
products and patterns to suit your needs.

tion 4 of this manual for details.
