Polaris 850 RMK Khaos 155
Research-based model profile$17,449
Read the source notes belowWhat this model is for
Khaos 155 puts WER Velocity Hi-Lo shocks and QuickDrive2 on the shortlist for a single mountain rider who wants adjustable equipment. The 850 Patriot badge represents a documented 840 cc engine. Against PRO RMK, focus on the rear-suspension design and dealer setup explanation rather than treating engine names as a power difference.
The 2.75-inch Series 8 and 3.25-inch Series 9 tracks are separate purchasing decisions, particularly for the approach to deep snow. Ask the dealer to demonstrate high- and low-speed compression adjustment and document starter/display options in the quote. If you cannot use the mountain route regularly, compare the cost of transporting this specialist machine with renting at the destination.
Consider it if…
- Mountain riders researching the Khaos suspension rather than choosing solely by engine badge.
- Owners prepared to set high/low-speed compression and select a mountain track.
Understand the compromises
- No exact manufacturer horsepower was found in the model specification.
- Single-person capacity; electric start is an option, not universal.
Specifications, with context
“Not confirmed” is an evidence gap, not a zero. Weight definitions, optional equipment, track choices and model years can change a comparison.

Equipment to understand
- QuickDrive2
- RMK React front suspension
- WER Velocity Hi-Lo shocks
Equipment can be package-specific. Match the listing, order sheet and model-year documentation rather than relying on a shared model-family name.
Questions to take to the seller
- Is the installed track Series 8 or Series 9?
- Does the quoted dry build include electric start and the chosen display?
- Can the dealer explain Khaos versus PRO RMK suspension setup?
