PROJECT ATV: DUNCAN RACING YAMAHA WARRIOR

Pro-level motocross and off-road riders turn to Duncan Racing International (DRI) to build championship-winning machines, but DRI doesn’t only develop engine and suspension packages for 450 race quads. They’ve got a wide range of upgrades for most popular sport ATVs, and all the parts are tested with the same concern for performance and reliability as […]

RZR Rescue: Making the old into the new

The Polaris RZR S 800, the first showroom-ready, pure sport, long-travel UTV, was a standard setting machine when it was introduced. UTVs have advanced so much so fast, yesterday’s cutting edge vehicles need some help to match the features and performance on today’s top rides. We grabbed a test rider’s RZR S and added a […]

PROJECT UTV: Polaris Sportsman Ace 350/570

The popularity of the single-seat Polaris Sportsman Ace is off the chain, and the introduction of the Ace 570 and 570 SP with EPS is great news for powermongers. The aftermarket is developing products for this new class of vehicle, and Polaris has three dozen accessories for the Sportsman Ace, including winches, snow plows, an […]

Davi Haagsma’s WORCS RZR

Unless you’ve been quietly living under a rock for the past few years, you’ve probably noticed the immense growth and recent popularity of UTV racing across the globe. While becoming hugely popular worldwide, the West Coast’s more open, desert-like terrain might possibly be the Mecca for side-by-side racing. The WORCS races pit some of the […]

RJ Anderson’s HOLZ XP1K 2

The XP1K is back, and they’ve gone bigger than ever for the sequel! RJ Anderson along with Mad Media and UTVUnderground.com have laid it all on the line again, looking to showcase the RZR XP 1000’s amazing capabilities, as well as one-upping their original creation. Mad Media and UTVUnderground launched the first viral XP1K video […]

PROJECT MACHINE: Suzuki LTR-450

Suzuki’s LT-R450 will forever hold a special spot in my ATV-loving heart. As the first ATV to be offered nearly race-ready right off the showroom floor, its OE 49-inch stance made it a no-brainer for motocross builds. High-tech fuel injection and great suspension meant the LT-R could competitively hit the track with just the addition […]

G-Force RZR XP 1000’s Turbo Powered

One of the greatest benefits of attending the Rally on the Rocks (ROTR) is that the aftermarket is there in force to demo its wares to a thousand UTV enthusiasts, so we get to see the latest and greatest products for already-awesome rides like the Polaris RZR XP 1000. Denver’s G-Force Powersports is one of […]

HCR LONG TRAVEL MAVERICK 1000

We tested the top-shelf 2013 Can-Am Maverick 1000 X rs in the January 2013 issue of ATV UTV Action magazine, and the machine had an impressive debut. Look on page 24 for a test on the base-model Maverick 1000, which doesn’t have the high-end Fox Podium 2.0 front and 2.5 rear piggyback shocks with dual-rate […]

HCR Racing Maverick 1000 X rs DPS Project UTV

Can-Am did a great job of improving its extremeperformance Maverick 1000R for 2014, adding triple-mode EPS and Visco-Lok QE (Quick-Engagement) front differential to two new performance packages: the 1000 X rs DPS (tested November 2013) and the 1000 X xc DPS (tested October 2013). We were stoked with both 1000Xs and had a blast ripping […]

Davi Haagsma’s Worcs-Winning H&M Motorsports RZR 570

FLOAT LIKE A BUTTERFLY The build for Davi’s 570 has a lot in common with Beau’s XP 900. It’s based on the complete Holz Racing Products RZR race Kit. This is a contingency-based kit that supplies a racer with proven parts that are ready to be bolted on. The HRP kit includes everything you need […]

Beau Baron’s #1 WORCS 450R

H &M Motorsports’ Beau Baron and Davi Haagsma took the West Coast ATV racing scene by storm last year. Beau won WORCS with Davi as runner-up, and then Davi won the QuadX championship and Beau earned second place. For a team to dominate like this requires near perfection in all aspects, and their race machines […]

Cylinder Works Big Bore Yamaha YFZ478R: Reviving an R on a budget.

Right out of the crate, Yamaha’s YFZ450R is one of the most effective high performance quads ever offered. It’s a monster that delivers devastating power and race ready suspension straight from the dealer. All it requires is gas, a rider and regular maintenance. Some riders have so much fun with the Yamaha’s performance they forget […]
