2022 Polaris Pro XP 4 Ultimate Super Graphite has been around less than two years. They seem to be everywhere, and with good reason. The basic platform and frame construction are on point and extremely robust. In the case of the RZR Pro XP 4, the cab can seat four in comfort, or the rear seats convert to a platform to securely carry equipment without eating up bed space or locating the load too far back behind the rear wheels.
Among the most important features are Ride Command and Dynamix Active Suspension 2.0. Ride Command is GPS integrated into a 7-inch glove-touch display, but the screen is also the communications and connectivity center. One screen is the Dynamix 2.0 Visualizer that shows exactly what the suspension settings are in real time. There is also digital Instrumentation, GPS, Group Ride (cell-based or GPS-based), topographic mapping, Bluetooth & USB smartphone connectivity, AM/FM & weather radio, and it is in-vehicle communications capable with optional Sena headsets.
Both the suspension and Ride Command are interconnected. Dynamix requires the GPS for calibration, and the display screen is required to show what the suspension is doing.
Dynamix has electronically adjustable Fox Live Valve shocks. Buttons on the steering wheel allow selecting Comfort, Sport and Firm general settings.

The quad’s TRX450R-inspired bodywork could be among the reasons for receiving such reverence (although I find that amusing since the Honda 300EX entered the ATV landscape way ahead of the well-renowned racer). If you are wondering, (yes!) you read that right — the Honda TRX300EX debuted in 1993 and stayed in production until 2012.
Now to the machine’s fine qualities. The Honda TRX300EX boasts a powerful 282-cc SOHC engine that delivers impressive performance throughout the entire RPM range. Engine smoothness is greatly improved — thanks to its gear-driven counterbalancer reducing vibrations for a smoother ride. Furthermore, its automatic cam-chain tensioner eliminates the need for manual adjustments, ensuring hassle-free maintenance.
A CDI system with electronic advance guarantees reliable starts, while an electric starter makes it easy to get the engine up and running.
As for breathability, the quad’s snorkel-type air intake is cleverly positioned high in the frame, minimizing the risk of water and dirt contamination — thus ensuring uninterrupted performance.
The Honda TRX300EX’s carburetion and powertrain systems and throttle responsiveness are also pretty impressive, as you will later discover in the next section.
