The IQ series name gives Polaris a re-start on the Fusion concept. It ousted the Fusion nameplate and hopes the baggage called “Warranty Issues” is gone as well.
Polaris has four models in this segment: the 600 HO IQ, the 600 HO IQ CFI, the FST IQ and the spring-only Dragon.
Other than the engines, the 600s and Dragon share several features. All come in the IQ chassis. All but the FST come with longer, fixed-position hooked handlebars; the FST retains the Rider Select adjustable bars. The machines use Polaris’ P-85 drive clutch and the Team Industries LWT driven. All have PERC push-button reverse.
The 600 HO is the most basic of the four, but marginally. Other than engine differences, it strays from the other machines with its mechanical fuel gauge and 10.8-gallon gas tank. The others have all-digital gauges with a 10.2-gallon tank on the FST and an 11.7-gallon tank on the 600 CFI.
The Dragon has the highest performance of the lot with a top-of-the-line suspension package. Its graphics differ significantly from the other models, and it uses a racing-style seat.

Liberty 600 HO CFI
This is a spicy version of the standard 600 HO and differs enough to be called new. “CFI” stands for CleanFire Injection, with two injectors in the cylinders and two in the crankcase. It’s cleaner-burning and more fuel-efficient than the 600 HO. It’s 599cc with 125 hp. Its features include auto calibration for changes in elevation and air, engine and exhaust temperature.
