There is a little confusion surrounding the difference between the Sidewinder R-TX 129 LE and L-TX 137 LE models in the rear skid frame area.
Last year the 129 LE mirrored the Arctic Cat ‘RR’ which included some heavy duty bits in the skid, bigger cross-shafts, beefy rails etc. Along with special geometry and premium shocks calibrated with a distinct lean towards racing.
Based on market feedback, it was decided to calibrate the ‘RR’ model with a more ‘real world’ approach. The sled offers more bump compliance for longer days in the saddle, yet still maintains a high level of durability. The skid frame design, geometry and components are now common to all the other models. The shock calibration reflects its aggressive positioning but is not as harsh as last years setting.
This set-up has been carried over from the 129 LE to the 137 LE. The only difference in components is relative to track length. In case you wonder, the Arctic Cat RR models reflect the same direction.
I confirmed the question regarding tunnel protectors on the Sidewinder. None of the sleds come with tunnel protectors. However the new tunnel strip heat exchangers have been designed to serve double duty as the protectors. You only need to add three short aluminum pieces to the rear most cooler and you’re good to go.
Hope this helps, remember the sleds we have in the field are not final with some components mocked up from last years parts bin.
