MPI ALL Cr-MOLY
A-ARMS for RX-1
|
| MPI A-Arms use an uncommon variety of Chrome-Moly, a carefully designed heat-treating process, advanced assembly techniques and computer-aided structural analysis to produce this part. The final product weighs almost 7 pounds less than the OEM arms & features hidden bolts to enhance looks and strength. They are available
for Mountain 4 Stroke Sleds in 38” or 41”. Short Track
RX-1 and Warrior choose from 42” or 45" widths. A separate Short Track
Version is also available for Short Track Apex, Attack and Vector in 42" and
45". Available in powder coat colors: Yamaha Blue or Silver. 41” kits widen Mtn RX-1,
Apex and Vector and includes lightweight tie rods. 45" Kits widen Short
Tracks. Short Track Kits do NOT work on Mountain Sleds and vise versa.
MPI also offers a lightweight shaft kit that saves an additional 2+
pounds. It replaces the inner and outer steel shafts with high strength
aluminum one. This kits is a must for any sled on a diet.
