The big news for Polaris fans for 2017 is the addition of a 174-inch track length on the Axys-based 800 Pro RMK. Aside from that, there's a new 600 RMK 144, and the Switchback Assault's move over to the Axys platform. 

All 2017 Axys-based models get a new, larger MessageCenter digital gauge. 

2017 800 Pro RMK 174 LE

You read that right––LE. As in Limited Edition. Most 174s will go out as Snow Check orders, but dealers will have a limited availability of 174s this fall. The 174 comes in one LE package, available in two color options: Titanium Gray / Orange and Titanium Gray / Lime Squeeze.

Here's the details on the 800 Pro RMK 174 LE:

• Purpose-built for climbing and flotation.
• Optimized to get stuck less and stay on top of snow.
• Instantaneous lift, rider balanced control, immediate response – same traits as the 155 and 163 Pro RMKs.
• Retained light weight (compared to competitor models).
• New RMK 174 Rear Suspension:
  • Lightweight and rigid.
  • Rear torque arm and rear shock moved back 3.75 inches.
  • Rear arm tunnel hanger moved back 3.75 inches.

• The entire chassis is rotated rearward around driveshaft (This raises the bulkhead angle up by 1.5 degrees and the tunnel is flattened by 1.5 degrees).
• The 174 comes with Series 7 3-inch track. (It's a 3.0-pitch)
• Chain case drive.
• Walker Evans Piggyback Clicker shocks (all LE models come with these shocks. They are the shocks that 60% of consumers picked on their snow checked RMKs).
• PowderTrac running boards (same length as the boards on 163 and 155).
• Titanium Gray with Lime Squeeze or Titanium Gray with Orange.

If you Snow Check your 800 Pro RMK 174, you get to select the color, handlebar height and storage options.
