A big part of the Polaris Ace’s appeal is that it doesn’t have what you don’t need. Lots of UTVers like to drive their own machines and rarely take a passenger along, so an extra seat is just extra weight. For many drivers, the ability to take extremely tight trails far outweighs the value of a wide ride with suspension that can handle high-speed whoop riding, so the Ace’s ATV-like 48-inch width is perfect. Not all UTVers who want a minimalist machine want it stripped down, so Polaris came up with the Ace 570 SP, an Ace with all the extras.
HOW DOEST COST COMPARE?
The Ace 570 SP is $9999. The base Ace 570 is $8499 and the Ace 500 goes for $6999. The Ace 900 XC is $12,999.
WHAT MAKES THE 570 SP SPECIAL?
More than looks. The big difference between the base 570 and the SP is the SP’s double-A-arm front suspension. The SP’s more sophisticated front end creates less bump-steer, turns tighter and offers more travel than the base Ace 570’s MacPherson-strut front end—9 inches versus 8.2. Both 570s have double-A-arm rear suspension with 9.5 inches of travel. All 2017 Aces have 10-percent more legroom.
The SP also comes with engine braking, power steering, painted bodywork, doors rather than nets, cast-aluminum wheels and a two-tone seat.
WHAT POWERS IT?
A single-cylinder, 567cc, double-overhead-cam, four-valve, fuel-injected engine with 45 horsepower.
WHAT KIND OF TRANSMISSION DOES IT HAVE?
The easiest kind to use. A fully automatic, dual-range continuously variable transmission with engine braking.
WHAT KIND OF 4WD SYSTEM DOES IT USE?
Selectable 2WD/4WD with an automatic-locking front differential. With the Polaris system, even when 4WD is selected, a speed-sensitive, automatic-locking front differential keeps the Ace in 2WD until the rear wheels lose traction. The instant the speed-sensitive front differential detects rear-wheel slip, the front differential locks and all four wheels are driving.
HOW FAST IS IT?
It moves! The 570 engine makes a number of 570 RZR models respectably quick and does a great job in the lighter Ace.
HOW IS THE POWER DELIVERY ON THE TRAIL?
The 570 has snappy, responsive power and enough muscle to conquer very difficult terrain. It has the unmistakably fun feeling of a light machine with a healthy amount of power. The 570 leaps forward from a standing start, and you can steer it with the throttle in 2WD. It’s tractable, too, so negotiating slick, sketchy sections of trail or technical rock ledges is no problem. When there’s room to let the 570 run, it’s satisfyingly fast, and the engine likes to rev.
HOW IS THE SUSPENSION?
Impressively smooth and capable. The 570 SP’s shocks aren’t high-end components, just low-pressure, non-reservoir, preload-adjustable gas units, but they do a great job of soaking up small impacts to deliver a plush ride and handling big impacts without bottoming. Thanks to its light weight, the Ace’s suspension handles jumps very well, especially considering it has less than 10 inches of travel at both ends.
HOW DOES IT HANDLE?
For tight trails, the Ace 570 SP is one of the best-handling UTVs available. The machine’s light weight, double-A-arm front end, front and rear sway bars and power steering give it outstandingly quick, nimble handling. It corners so flat, so securely and slides so predictably, it’s hard to believe the thing is just 48 inches wide. That width opens up a whole world of trails that most UTV drivers can only dream about.
HOW IS IT ON HILLS?
Confident. The 570 has plenty of power for its weight, and the 4WD system grabs traction even on dry-packed soil that seems to offer no grip whatsoever. Engine braking makes negotiating tricky downhills simple, but it would be better if the engine braking system worked on all four wheels, as it does on some Polaris machines and many other brands’ UTVs.
HOW ARE THE DETAILS?
The 570 SP has a nice group of premium features that we’ve already mentioned, including power steering, painted bodywork and others, but the vehicle itself has some touches worth mentioning. The Ace is easier to get into and out of than many larger UTVs, and the bodywork provides better splash protection than most pure-sport UTVs. The seat has a slide adjuster like a car’s seat. Some UTVs’ seats aren’t adjustable. The wheel tilts, and there’s a cup holder, full instrumentation and a glovebox. There are some rough edges too. The Ace’s transmission range selector isn’t as slick or positive as some.
WHAT IS OUR FINAL ANSWER?
The light, agile Ace platform and the light, powerful 570 engine is a great combination. When you add the Ace 570 SP’s useful extras, like double-A-arm front suspension, power steering, engine braking and doors, you have one of the most fun UTVs around, and it’s under $10,000.
