Sport Quad

Dan Mayer’s second time around By the staff of Dirt Wheels, Photos by Pat Carrigan It is an old story: parents, trying to do what they think is best for their kids, forbid the purchase of an ATV. Often, as is the case with Dan Mayer, quads become the forbidden fruit and a life-long obsession is born. This Duncan Racing 2018 Lobo-chassis build is the latest milestone in Mayer’s dedication to magnificent quads. It turns out that Mayer was a die-hard Dirt Wheels reader as a youth, and he was drawn to the radical…

By the staff of Dirt Wheels 2020 HONDA TRX250X This may not be the infamous and cultist TRX250R two-stroke ripper, but the humble Honda TRX250X has outlasted and sold in greater numbers than the old two-smoker. One is a pure-bred racing-style ATV, while the other is the perfect transitional ATV, or even the final landing, for riders that don’t need a lot of power. Honda’s 250X is their only sport ATV for older youth riders and adults that is still available. The TRX400X and favored TRX450R have long since left…

2021 YAMAHA YFZ450R /YFZ450R SE The YFZ450R is the most technologically advanced sport ATV on the market today, with a quick-revving, 449cc fuel-injected engine and titanium five-valve cylinder head delivering abundant power throughout the mid- to top-end, after the YFZ’s signature massive torque-feeling right off idle. Built with pride at Yamaha’s U.S. factory in Newnan, Georgia and motocross-ready, the weldless professional-caliber frame is designed from lightweight aluminum with a tension-steel bottom frame…

From our March 1998 issue of Dirt Wheels. MORE INFO:  https://dirtwheelsmag.com/ultimate-off-roader-honda-trx600/  PROJECT HONDA FOURTRAX TRX 600: BUILDING ULTIMATE OFF-ROADER “Honda should have made this years ago,” said reigning Grand Na­tion­al Champ Shane Hitt after his first ride aboard Dirt Wheels’ Project TRX600 sport quad.  had just put the machine through a grueling test ride at DW’s exclusive Club Moto torture track—a track, mind you, that few “race” quads would feel comfortable on, much less a…

Feb 98 **Editors Note-A test of a one-off prototype racer to replace Honda's FourTrax 250R. Rebel Star one-off racer.  A replacement for the Honda FourTrax 250R? Ever since the wildly popular Four­Trax 250R disappeared from Honda’s line­up in ’89, racers throughout the country have been screaming for a ma­chine as good as, if not better than, the FourTrax. Sure, there are plenty of other sport and performance machines on the market to­day, but none are as fast on the racetrack (in the modified form) as the…

What's it like to ride.

What the factory should have built long ago...

Jan 98 By Adam Campbell Coolest MX Track Ever When I first pulled into the Midstate Motocross Park, in Litchfield, Kentucky, I knew I was in for a treat. We had heard ahead of time, that this was one of the most scenic motocross tracks in the entire country. However, I never would have guessed just how cool it could be. You see, I have spent my entire rac­ing ca­reer on the mostly burned-out, hardpack tracks of Southern Cal­i­fornia. Ev­ery once in a while, we get a nice moist race track, or a loamy, sandy…

Thumper Talk As the riding season winds down, it may be a good time to get your four-stroke ATV running up to its full po­tential. To help you out, we talked with some of the top four-stroke tun­ers in the country and asked them to lay out their best performance tips. From the Northwest, we contacted vet­eran wrench, Pete Fisher, from Pow­roll Performance up near Bend, Oregon. For the East Coast, we got shop owner Micky Dunlop from Four-Stroke Tech (https://4stroke.wixsite.com/mysite  ) to dislodge his Thumper Talk…

By the staff of Dirt Wheels KAYO USA 200 JACKAL When we picked up the sporty Kayo  USA 200 Jackal, our only experience with quads from this Chinese company was a brief exposure to the Kayo 150 Storm. The Storm uses a lay-down engine like the Honda TRX90 but with more power. The Jackal is a 200cc upright engine, and it looks like a generic single-cam 200 engine like you would see in an ATC200X or a Yamaha TT-R225 dirt bike. This is a proven engine design and one that has proven reliable from Chinese engine…

By the staff of Dirt Wheels QUADS OF THE WORCS RACES. World Off-Road Championship Series (WORCS) is one of the major quad competitions on the West Coast. It requires an interesting combination of motocross start, jumps, and turn skills, but the courses are much longer and the races last for an hour. We went to the season opener at Primm, Nevada, and the course seemed like it held several hundred turns. We can’t imagine that anyone could memorize the entire course like a motocross race. For the past two years, the…

By the Staff of Dirt Wheels RADICAL YAMAHA BLASTER BUILD! Hunter Lovelace hails from Muskoka Canada and likes to build brilliant old school custom ATVs. He took one of his old prized machines, a 1988 Yamaha Blaster, and decided to rebuild it better than before for his younger brother. A lot of the parts that Hunter installed are near impossible to find these days and give it a custom look and feel from the 90's! The mods include: Motor: Duncan / Paul Turner ported, decked, and polished motor, 175 PSI…
