AMS M4 TIRE TEST

-- a smooth riding and durable top performer -- The Maxxis Big Horns that come stock on most machines are great general-use tires that are very comfortable. They get decent traction in all terrain and provide a very comfortable initial ride quality. However, after your first few rides or first couple punctures, you will most likely be looking for something a little more durable and terrain-specific. If durability is what you are after, but you still want a new tire to work in all situations, zero in on at least an eight-ply…

EASY WAY TO GET 10-MPH SPEED INCREASE

THE TROUBLESHOOTER -- BY SARGE McCOY Dear Sarge, I own two Polaris’—one is an XP 1000 with tracks that we use in the wintertime, and the other is a Ranger 570 Crew. We accidentally discovered a way to increase the speed of the little 570 by 10 mph! On the XP 1000 with tracks, we installed a HealTech Electronics SpeedoHealer V4 to force the Polaris speedometer to read correctly. With the track set up, it was almost 50 percent faster! During the summer when we mothball the 1000 and use the 570 Crew for transportation, we…

HOW-TO: CONVERT YOUR UTV TO 32-INCH TIRES

-- Guide to the pros and cons -- With more and more manufacturers introducing 32-inch UTV tires, we’ve had to convert our long-term test UTVs so we could accurately test the new offerings. Very few UTVs come with 30-inch tires, and most are fitted with 27- to 29-inch rubber with very low ply ratings, so manufacturers can brag about low vehicle weight. With 32-inch tires being on the verge of replacing 30-inch tires as the new “normal,” let’s take a look at their benefits and drawbacks. WHAT ARE 32-INCH ADVANTAGES?…

POLARIS RS1 PERFORMANCE UPGRADES

-- Walker Evans Racing build -- Polaris is enjoying great success with its first extreme-performance single-seat UTV. The RZR RS1 has racked up several major race wins, and we’re seeing quite a few of them in the dunes and desert. We tested the long travel, HCR Racing RS1 at Moab for the September 2018 issue and the Shock Therapy RS1 at Camp RZR for the April 2019 issue. Both were very impressive. We also got to try the Walker Evans Racing (WER) Hot Randy Special RS1 at the SxS Adventure Rally held at Sand Hollow State…

STEERING WHEEL BUYER’S GUIDE

-- Here are the top aftermarket models you should know about -- The first time you drive with an aftermarket steering wheel, you’ll want one. Stronger, race-quality wheels give you more direct steering feel without the flex some stock wheels have and the added style of high-quality materials and finishes.

We collected the most impressive wheels from the top…

2020 POLARIS RZR PRO XP

-- Test drive in the 181 hp machine -- The Polaris RZR platform is an ever-growing and -evolving beast. It came into this world as a tiny 50-inch-wide machine that made it the first UTV able to ride narrow ATV trails. That fact and the aftermarket’s (mainly HCR and Pro Armor) quick reaction to modify it made it an instant hit. In just over a decade, Polaris has pumped out over a dozen versions of the RZR that still cater to everyone from that narrow trail rider to the wide-open desert racer with the 72-inch-wide Turbo S…
