PROJECT ATV: Suzuki LT-R450 Restore – Duncan Racing

Back in 2005 and 2006 when the sport quad industry was booming, every manufacturer was in a race to come up with the best performance 450 around. First was Yamaha, and then came Honda with their trailready 450s. Suzuki shocked the industry by coming out with the first production sport ATV with a 50-inch-wide stance […]

ATV TEST: 2015 Yamaha YFZ450R Special Edition

Yamaha’s YFZ450R is one impressive sport ATV right out of the box. The engine is powerful, the suspension outperforms all other stock sport quad suspensions, and the overall performance of the machine is very satisfying.

HOP-UP TIPS: Pull more power out of your machine! Dyno testing

The aftermarket parts industry for ATVs and UTVs is continuing to grow, yet choosing the right performance products for your machine is not always a simple task.

When Suzuki introduced the track-ready, 49-inch wide LT-R450, they turned a lot of heads. Now amateur MX racers had a machine they could take off the dealer showroom floor, add a few safety features, and race it that weekend. They would save thousands in aftermarket A-arms, shocks and tires. Furthermore, Suzuki had a product that […]

SHOOTOUT: 2008 Raptor 700 vs. Honda 700X

When we got the call that our Honda 700XX was ready for testing, we had just finished up our big-bore sport shootout. That contest featured the Polaris Outlaw 525, the KTM 525XC and Yamaha’s Raptor 700. The results were very close with the $7400 Raptor just edging out the 525 from KTM. So we decided […]

SHOOTOUT: Sport quad 450 Duner Shootout

Back in the June issue we brought you a shootout using these same three quads. In that test we took them for a day of riding in the tight trails.

ATV TEST: Racing 450 Shootout

This is the golden age for performance quads. Ten years ago, we were patching up old two-strokes from an earlier era, hoping to get them through each week while the manufacturers virtually ignored the high-end sport market. Now we have at least six makers offering state-of-the-art 450 sport quads with performance we could only dream […]


It’s coming. But it’s not here yet. We’ve been hearing the rumors, watching the market and listening for clues, and it seems that Honda’s new sport 450 is right around the corner—but will probably be called a 2018 model. We hope it will be far more than a fuel-injected version of the current 450R. The […]
