While the Switchback is still offered with a carbed 600 H.O., a 900 twin or the turbo 4-stroke, the new kid on the block is the 600 H.O. CFI. Polaris listened to their dealers and consumers and shortened the chassis length of their Switchback models by 3â€. Additionally, the weight of these machines has been reduced by five pounds. All of these models are still too long with their 144â€ track length, despite a shorter dovetail (tunnel) extension for 2007. Compared to the 136â€ track lengths from the rest of the world, the 144â€ track length of the Switchback does add flotation in deep snow, but the added length really shows up on the trail, even with tipped up rails. The running quality is outstanding, the rear suspension pretty capable (when set properly, most riders donâ€™t even know the compression adjuster is in there, with the knob so well hidden in the rear suspension) and the handling gets better as it gets rougher. Flat trail riding could use more bite up front; the track length pushes. So, where is the 700 Switchback (instead of two 600s)? The FST is the 140 HP entry instead.
