Designed for overall fun, the 2024 YETI SnowMX 129 FR is a proven strong and responsive YETI for all-round agility and boondocking, day after day!

RIP IT OPEN AND RIDE IT LIKE YOU STOLE IT! IT WILL TAKE THE ABUSE!

129 SS 10" wide track, 5.5" rail spacing, narrow carbon chassis

The YETI 129 SS is the most nimble all-round YETI favourite  that makes the most of your motocross bike. The SS model has the narrower carbon chassis that carves best for the aggressive lighter weights rider who want the most playful unit all around. But don't let it fool you in the deep either, this unit with its narrower chassis digs a trench with less side friction, cresting hills you think you won't.

 With Camso's next gen 2.6" lug height track, reshaped for all-angle traction and upgraded suspension that stays firm eating up all obstacles. Shed weight, not strength with pure carbon fibre reinforced with aircraft grade aluminium.
