Suspension improvement recommendations for:

Yamaha Viper 129 and 137 track, 
Arctic-Cat ZR 129 and XF 137 track.

About those suspensions:

Those rear suspensions are very similar. There are some differences on the configuration of the rear shock assembly between 129 and 137 models, but shock dimensions, suspension travel, spring selection and shock valving is identical (2014 models). RTX SE or Sno-Pro models have a bigger rear shock than the basic models.

We made some rigorous testing on those snowmobiles on Winter 2014, and we came up with an excellent setup for trail riding comfort and cornering improvement:

Rear suspension revalve and modifications:  190$

This include: 

  • Rebuilt and revalve of the rear shock
  • Rebuilt and revalve of the center shock
  • Center shock piston modification
