Legacy 2-Stroke (SX / Vmax)

Modern Performance for Classic Triples

The sound of a Yamaha triple is unmistakable, and sleds like the Vmax SX, SRX 700, and Mountain Max are still some of the most exciting machines on the snow. But the original ProAction rear suspension and early front-end geometry can feel harsh and outdated compared to modern sleds.

Don't retire your classic just because the ride is rough. We specialize in updating these vintage platforms with modern valving and high-quality shocks, giving you the best of both worlds: classic 2-stroke power with a plush, controlled ride.

In this category, you will find:

• ProAction Upgrades: Specialized shock packages to fix the "harsh stutter bump" performance of the ProAction rear skid.
• Restoration Shocks: Direct-fit gas shocks from Fox and Custom Axis to replace worn-out, non-rebuildable OEM units.
• Rebuild Services: Full service for factory KYB and Ohlins shocks found on SRX and SX-R models.
• Long-Travel Conversions: Parts and shafts to help service or upgrade the "ProAction Plus" suspension.
