We also find the rear arm is mounted very far back on the rails. More importantly, we have separation of the springs and shock on the rear arm, and it is coupled. With the PRO-CC design we go back to a more linear “rising rate” motion ratio for the rear shock. On those sleds the ratio is “progressive” in that it starts out soft and ramps up firmer through the travel. On the RUSH & Switchback models, the coil spring is on the rear shock thus they have the exact same motion ratio. The rear arm has torsion springs (like the 144” Assault) so the shock and springs again go back to their own motion ratios. The front arm is the exact same geometry as the front arm on the current RUSH & Switchback sleds, but with a softer calibration since the PRO-CC goes back to a two-way coupled design that combines the shock and spring action of both front and rear arms when coupled. This rear suspension combines many of the lessons learned and knowledge gained over the past several platforms and delivers performance across a wider range of conditions, for a wider range of riders. In order to build a 129” AXYS model, Polaris engineers rolled up their sleeves and developed yet another excellent rear suspension called the PRO-CC. The market will decide what kind of sleds will survive and which will be dropped from the line-up, so we will let that take its natural course. They do not (yet) replace the beaver-tail RUSH, but they very well could in a year or two. You might think the 2019 Indy XC sleds are going to be value models, since they bear the Indy name, but they are not value sleds. AXYS platform, good shocks, straight tunnel. Like a 129” version of the Switchback Assault. Not a value model, but a full-blown high performance model. We just couldn’t help ourselves in wishing for a short track version of these sleds.
Since 2015, with the introduction of the AXYS-platform RUSH and Switchback sleds, Polaris has brought us the AXYS RMK and AXYS Switchback Assault models.
