At mid to high speeds (which these two potent units are extremely capable of reaching) is where the absence of EPS or a steering stabilizer can really cause the pilot painful troubles. This is when clipping a stump or rock that's hidden beneath the underbrush or snagging the edge of a tree trunk can bring your good times on the trail to an abrupt halt. Fortunately, EPS reduces the likelihood of the bars being ripped from your hands. This extremely vital feature is mechanically accomplished in the same manner as steering with your arms. The main difference is that EPS multiplies the exerted force, which in return helps the rider hold the handlebars in their desired direction. Those particular benefits alone were enough to convert me into a believer of this technology.
Performance Notes
While both of these ATVs are equipped with comparable systems, there were highly noticeable differences in the performance characteristics and function of the two. The Can-Am Outlander's dual-mode feature allows the rider to easily switch between minimum mode (less assistance) and maximum mode (more assistance) via a bar-mounted control, which we thought was extremely useful. Switching back and forth was easy once we grew accustomed with it even as we navigated rough terrains. There is a drastically noticeable difference between the two modes, and our test riders preferred to remain on the minimum mode for the majority of the time spent riding. They reported that the maximum mode actually felt as if it provided a bit too much assistance. Don't be alarmed; it's not a wasted feature as situations did arise where the maximum mode became beneficial and could certainly be appreciated. The maximum mode felt as if it slightly reduced the Outlander's predictability at mid to high speeds, but switching to minimum mode brought back that lost predictability.
The only negative we found on the Outlander EPS's performance was its strange mechanical feel. Rather than portraying a smooth, fluid motion, we were always aware that the EPS motor was at work as it portrayed a slight tug back and forth on the handlebar. Can-Am's EPS system is a highly advanced one and, just like any innovation, it has its pros and cons. Overall, we felt this system performed at a high level and drastically reduced our fatigue throughout the day. I mentioned earlier that I prefer things to be simple, but all three test riders (including me) agreed that the dual-mode system is an added bonus and a huge success. So in this case I'll let the high-tech dual-mode feature slide. After pounding this system and realizing just how well it performed, I can honestly say it is worth the upgrade for those willing to spend the extra money.
As for innovation, Can-Am's...
As for innovation, Can-Am's dual-mode feature incorporated into its EPS design was brilliant. The ability to dial in the amount of assist for the terrain and situation the rider is in should be something we see more of in the future. Hopefully all manufacturers will take notice of this brilliant concept.
I had mixed feelings about the initial feedback I was receiving from my test riders on the Polaris Sportsman. They first pointed out that the EPS wasn't overwhelming and obvious while riding. This concerned me because I knew the Polaris system wasn't adjustable, which proved to be a phenomenal feature on the Can-Am. No matter which side of the spectrum, an overly light or overly heavy feel in the steering generally equals negative performance of an ATV. It wasn't until I had my chance in the saddle of these two beasts that I realized our test pilots weren't complaining about this characteristic, as it portrayed a fluid and consistent feel at all times. It's not until you find yourself in situations that would typically take serious effort to turn and maneuver through that you take note of the Sportsman's ease of operation. The system's variable assist EPS creates a natural feel that functions well without drawing the rider's attention. When driving or riding any type of vehicle, it should provide a natural and comfortable feel, and that's exactly what the Polaris accomplished.
