PERFORMANCE WITH VERSATILITY TO RIDE IN ALL CONDITIONS. The Timbersled SX 120 began as a purpose-built race machine - but has proven to be equally at home in the steep and deep as it has on the trails of the mid-west. A 2” narrower track, chassis and tunnel with a race specific frame and suspension provide the ultimate motocross feel and handling for all snow conditions. Features may include: 120" ULTRA-RESPONSIVE NARROW 10.5” CONVEX 2.5 TRACKThe new Convex 2.5 easily outperforms all other designs by increasing efficiency, handling, and reducing weight. The specific “Convex” shape mimics a tire making it easier for trail and hard pack riding. LONG ARM CONVEX PIVOTING SUSPENSIONThe most efficient, best climbing, smoothest riding long travel rear snow bike suspension available on the planet. It also utilizes Front Flex Arm technology that feels narrower like a tire, and helps keep your bike level as you ride across uneven terrain. RACE INSPIRED SUSPENSIONNow featuring custom valved FOX ZERO QS3-R shocks. QS3 (Quick Switch 3-position) - Quickly change between 3 specifically calibrated settings (soft, medium, and firm) with a "flip of a switch" to adapt to varying trail conditions. Plus, adjustable rebound setting allows your shock to recover from bigger hits quickly enough to absorb consecutive hits and provides increased traction.
