GEAR GRINDER: DYNOJET POWER COMMANDER V & AUTOTUNE

-- Fueling our race-ready YXZ’s thirst, By the staff of Dirt Wheels -- Our YXZ1000R SS creates decent power at around 112 horsepower from the crank, but it’s not enough to holeshot the competition at a WORCS race. You may recall that we installed a full Akrapovic titanium exhaust on this machine, and when you install an exhaust for closed-course racing, you need to add the correct fuel mapping or you could damage the engine. Since all the new performance UTVs and ATVs are fuel-injected, simply changing out a jet…

TUESDAY TREAD: ITP DUNE STAR TIRES & BLACK OPS SS316 WHEELS

-- Close-to-perfect UTV/4x4 quad sand tires --  Tire test by the staff of Dirt Wheels. The ITP Dune Star tire breaks new ground for us. Here is a tire that has a sharply narrow focus limited primarily to sand, but could also be effective in snow or mud. Keep it away from hard dirt, but when used in the sand it was designed for, the performance is flawless. The single fault we can find is that it currently fits only 12-inch wheels. End of complaints. FEATURES Most sand tires are designed…

S&B PARTICLE SEPARATOR FOR YXZ1000R MODELS

-- A safe engine is a happy engine, By the staff of Dirt Wheels -- Our race-project YXZ1000R SS is subjected to some pretty intense, dusty environments. We recently entered a Dirt Series motocross race in SoCal, and it became a dusty mess. After checking out our air filter, it was apparent that we needed a product to keep the filter clean longer. The brainiacs at S&B Filters put their minds together to produce a product that would cut down on harmful dust particles that enter UTV intakes. They’re experts in…

GEAR GRINDER: ORI STRUTS

Use nitrogen for your UTV springs By the staff of Dirt Wheels Mark and Marie Jensen used their passion for design and off-road racing and Mark’s nearly 40 years of machining, engineering and ISO 9000 global-standard quality-control experience to fabricate their first suspension systems. They later incorporated ORI Struts as a company in 2002. Mark gained his appreciation for precision engineering as a Honda motorcycle mechanic, and later as a machinist before completing formal studies in manufacturing engineering. He…

TUESDAY TREAD: BRAVEN OFF-ROAD IRONSIDE TIRE & WHEEL

--Testing a brave new lineup of wheels and tires -- It’s a dog-eat-dog world when it comes to producing and selling tires and wheels for any platform these days. Getting tires produced is somewhat easy for companies to do, especially with the rise in rubber manufacturing in China, but the hard part is to build them to last and perform. For a new company, this would be a daunting task to try to get it up off the ground and market their products correctly to the UTV and ATV world. Some might say it’s too tough, but…

GEAR GRINDER: DRIVE-OVER CHOCK

-- Peace of mind while trailering your rig By the staff of Dirt Wheels -- Having your machine securely fastened to your trailer is not only good for your machine, it’s good for your sanity and the safety of yourself and others while driving down the road. We’ve all been there a time or two: we get out of our vehicle after driving down a beat-up road and, despite tie-downs, our machines have moved on us during transport. It’s not a good thing, especially if you have no back gate, or are hauling multiple vehicles. The…

TUESDAY TREAD: ARISUN THUNDER MT TIRES & RACELINE A77 MAMBA WHEELS

A great setup for your utility quad By the staff of Dirt Wheels Arisun Tires and Raceline Wheels are one in the same. Arisun Tires is known for making some gnarly six-ply and eight-ply ATV and UTV tires. Some are specific to certain terrains, while others are awesome all-terrain tires. Raceline Wheels makes wheels for trucks, UTVs and ATVs. Their UTV and ATV wheels are built tough and can be purchased in simulated beadlocks, double beadlocks or standard beadlocks. Two of their products that caught…

SIDI X-3 LEI WOMEN’S BOOTS

-- What the fairy godmother should have put on Cinderella’s feet -- By Rachel Bosemer and the staff of Dirt Wheels In prior years there was a limited selection of women’s boots available. For as long as I have been riding and racing ATVs, Alpinestars has dominated this market. After years and years of waiting, Sidi finally released a women’s boot that has as much technology and style as the men’s counterpart. Sidi has always been known as a leader in boot technology, so it was finally time for them to be put…

MAMBA BEADLOCK WHEELS & AFTERSHOCK TIRES

-- A race-winning combo from Raceline & Arison -- Raceline Wheels is a product of the famous Allied Wheel Company. Allied started out building quality automotive wheels in Southern California, where they still operate. Wanting to build on its already stellar resume, Allied added another brand, and that’s when Raceline was born. Raceline wheels are produced for cars, trucks, and now ATVs and UTVs. We’ve tested many of their wheels on our machines through the years, and their quality is…

TESTING AMS SIDEWINDER SAND TIRES

There is a genre of tire for every type of terrain, and that is extremely apparent when it comes to shredding sand dunes. Sport ATVs are also a very worthy tool to tackle the steep and flowing mounds of sand, so pairing the two creates a combination of pure fun and enjoyment. AMS designs tires with tread patterns to suit all types of riding, and that includes their Sidewinder rear paddle tires. We tested their rear set of AMS V-blade-style sand tires on our Honda TRX450R. AMS SIDEWINDER We have…

YAMAHA GENUINE YXZ1000R PRODUCTS

-- Yamaha knows best, By the staff of Dirt Wheels -- Shopping at the source for quality parts can sometimes be better than searching online for countless hours. Take Yamaha Genuine Parts, for example. Yamaha builds their UTVs and ATVs to be of the best and meet every quality standard possible. To do this, they spend countless hours and dollars to make it happen. Besides, they built the car and put in the R&D, so they know a thing or two about what they build. If they can’t do it better than an aftermarket company,…

Tuesday Tread: Pro Armor® Hammer Tire & Wyde Wheel

UTVs are sold all over North America, and it hardly makes financial sense to equip machines headed for different parts of the country with different tires. Pro Armor knows that not every stock tire is most effective for where each rider may live. The Hammer uses 20mm tread blocks that are fairly close together, and perhaps more importantly, none of the center tread blocks run sideways. They are largely oriented along the length of the tire. That orientation puts a lot of rubber on the ground, and makes for a very…
