PROJECT UPDATE #1: 2019 Polaris RZR XP Turbo S Velocity

We are taking a 2019 Polaris RZR XP Turbo S Velocity and upgrading it to handle the abuse of rock crawling and desert driving. Parts from companies like BFD Off-Road, WARN, Assault Ind. and more are finding their home on this impressive build.

WHERE IS THE ALL-NEW HONDA TRX450R?!

We can't hide the truth. Our beloved sport ATV market has been taken over by roll cage equipped machines. Do we want to stick our noses up at the UTV market? Of course not! Those machines are a blast to drive, and get more people included in our favorite hobby: off-roading. But, if we are honest, we are very bummed out that the sport ATV market has fallen off the radar of most major manufacturers. In fact, Yamaha is the only remaining major manufacturer that offers a race ready 450 and a trail ready 700R straight axle sport…

2019 SUZUKI KINGQUAD 500 & 750AXi RIDE REVIEW!

Suzuki just released their 2019 KingQuad 500AXi and 750AXi. We got to test the new 4x4 ATV model in the woods of North Carolina. The quad handles great and looks just as good as it rides!

TOP PROJECT ATVs

The Dirt Wheels crew will ride a box-stock quad for awhile, but then we start thinking about ways to improve its performance. Building project quads is a way of life for us.

PROJECT RAPTOR 734 GETS 76 HP!

We like to cover the spectrum of affordability with our projects. Some, like our Honda 400X, are affordable, easy and very effective. For our project Raptor, however, we decided to not constrain the project with a budget but rather shoot for the stars. With the Raptor in pieces in Trinity’s shop, we compiled some other parts to install for part one of the project Raptor build. If you’ve been keeping up with our Facebook page at www.facebook.com/dirtwheelsmag, you will recall some of the build pictures and…

PROJECT ATV: Duncan YFZ450R

Over the years we have tested many fully built machines that we have given rave reviews over and some we haven’t liked much at all. Since the new sport ATV world is stagnant at the moment, we have been building plenty of older machines that prove that they are still very worthy of competing. Our last build with Golden West Cycle and Duncan Racing turned out very well. The WORCS-style Honda 450R we built was great on the track, trail and in the dunes. Afterwards, we contacted Duncan to build us a full MX-style YFZ450R with…

PRO-BUILT: THE NATIONAL CHAMP’S YFZ450R

Make your Yamaha rule the trees By the staff of Dirt Wheels It takes a special type of talent and drive to be a GNCC pro ATV champion and an even rarer sort of person to win multiple titles in a row. As you might imagine, winning those championships also takes a very special sort of YFZ450R. No matter what quad you ride, you can learn from a quad champion like Walker Fowler. His race quad is tuned and tricked 100 percent to suit his kind of racing. The mods are not just about performance; to win, you must…

PROJECT: Yamaha Turbo Raptor 700

Yamaha’s Raptor 700 is a force to be reckoned with in the world of sport quads. It is the top big-bore sport quad around and is the last one that is still being manufactured today. The Raptor 700 is fast in stock trim, but Roger Kirkpatrick from Humboldt Motorsports was tasked with taking a 2007 Raptor and turning it into a mean sand-slinging machine. Bolting on parts to increase the machine’s handling and performance capabilities was very important with this build, mainly because a very powerful turbo system was about to be…

PROJECT ATV: Fast Yamaha Raptor 700

We believe the R&D department at Yamaha sent a team of scientists back in time to capture one of the most ferocious dinosaurs around, the Raptor. It was fast, powerful and aggressive, just like the Raptor 700R, so it would make sense that they somehow mechanically enhanced the dinosaur with four wheels and produced it as one of the most iconic sport ATVs around. In terms of power and performance, you can’t easily beat a Yamaha Raptor 700R. The only way to do so is, well, to make it better by bolting on aftermarket…

2016 Polaris RZR Turbo Review

The release of the 2016 Polaris RZR XP Turbo raises the bar in several areas. One, at a claimed 144 crank horsepower, the RZR Turbo is the most powerful UTV made. However, at $24,999, it’s also the most expensive standard-edition, two-seat model as well. The latter hasn’t seemed to affect sales so far, and we already see dune areas in the Southwest dotted with them. ALL-NEW RZR To our surprise, Polaris didn’t just slap a turbocharger onto the existing XP1K platform; they gutted the old machine and made a ton of…

BUYER’S GUIDE: 2016 Sport ATVs

Another year has passed, which means new and exciting ATV models have hit the market. Nowadays, these machines are coming with more features at better price points. Power steering is becoming a standard feature on a lot of new machines, which is a nice thing to have. The 4x4 market is gaining new models every year, which is a major plus; unfortunately, the sport-quad side of things is beginning to dwindle. There are less offerings of sport ATVs than we have seen in a long time. Yamaha’s Raptor 250 and 125 have become more…

YAMAHA’S GNCC ATV RACERS

WALKER FOWLER Starting off the 2016 Grand National Cross Country (GNCC) series at the top of the podium, N-Fab/Am Pro/Moto-XPerts Yamaha-sponsored Walker Fowler will defend his XC1 Pro ATV class title after securing the 2015 championship aboard his YFZ450R at only 22 years of age. Despite his youth, Fowler brings a decade of two and four-wheel experience to the podium, finishing every series no lower than second since his introduction to GNCC racing in the 2006 GNCC 90cc mod. class.
