An MX or desert racing quad, like this Honda 450R from Teixeira Tech, makes for a great high-speed duning machine.

In our March/April 2013 issue, we gave you over a half-dozen advanced riding techniques. But you're going to need a fast and great-handling machine to pull them off. Turns out, an MX or desert racer like Ed Teixeira's Honda here, the same machine you saw in our last issue, is just about perfect for raging around the dunes and attacking everything in sight.

Ed's company, Teixeira Tech, designs and builds A-arms and components that are second to none, and Ed's resume includes plenty of MX racing, plus top quad honors at the '07 Vegas to Reno (the longest off-road race in the US) and the Best In The Desert championship that year.
On a recent weekend at Pismo, Ed showed me some of the setups on his highly modified Honda 450R, and we hit the dunes where I compared his R to my modified KTM 525XC, both set up for going as fast as humanly possible in sand. This is what ‘ya call fun, Jack!


Both Ed and I run CT Racing modified motors, his more modified than mine, but they both rip. CT Racing provides the exhaust on both. The Honda has CT porting, plus Wiseco high-compression piston, valves, and clutch basket. Ed's 450, as you'd expect, doesn't have the torque of my 525, but it revs higher and is snappier. For most people, that makes for a more exciting ride, even though mine might pull a higher top speed and beat the Honda in a long drag race.
Good luck finding a better front end than this. Teixeira’s A-arms and Fox’s new Kashima shocks. Teixeira’s aluminum products like the front bumper and grab bar may not be entirely necessary for the dunes, but they sure look great.
For his desert racing, Ed runs an FPS radiator, which has about 50 percent more capacity than stock. Even at Pismo, the constant starting, stopping, and idling for a photo shoot can generate quite a bit of heat.

Sand will eat up a motor faster than anything, so Ed runs an Outerwears lid over his Uni foam filter. For full-time duning on his 450, I'd probably run a K&N filter and lid. Sand is also hard on sprockets, and Ed likes Dirt Trick's Ironman products. Even though the sprockets are tooled steel, Ed says they're lighter than stock, and last him five years.
It’s not the best setup for hill racing, or for a casual duner, but for going as fast as possible through the dunes, the motor and suspension on an MX or desert racing setup work really well. The PowerMadd handguards not only look good, they might come in very handy when whipping through the trees at the Oregon Dunes.

There are two schools of thought on quad width. Stock width turns more precisely (for snaking around trees at the Oregon Dunes), and it offers more straight-line hook up and control for drags. But, for someone who likes to attack whoops in fourth gear, and needs more stability should he land a little sideways on a monster jump, wider A-arms are the way to go. Ed runs his own Teixeira Tech MX arms, which are chromoly and add 2.5 inches per side. The reverse gull wing design not only allows more suspension travel before bottoming out, it's less likely to slow you down in deep buggy sand ruts. Instead of Heim joints for the tie rod ends, which can be more susceptible to the elements, Teixeira runs steel, sealed ball joints.
CT Racing and Wiseco are responsible for motor mods. For full-time duning, the skidplate would have to go, but for desert racing it’s indispensable. Teixeira’s burly, stainless footpegs provide a solid, secure platform. If your foot does somehow slip off in some deep buggy ruts, the heel guards will probably save you from running over your own foot.
Fox wanted us to test their brand-new, cooler-running Kashima-coating upgrade on its Float X Evol shocks, and it's literally a very cool process. Because the Kashima makes for a super-slippery surface, there's less friction between the shock piston and shock body walls; Ed notices this advantage in really choppy sand. Although the stock shocks (with Teixeira arms) on my 525 are amazing, I found these Fox units to give even smoother performance in whoops. There are no springs, making the shocks lighter, and two air chambers provide dual or triple rate suspension action. Both Stage 1 and Stage 2 Evols can be upgraded with Kashima. Out back, Ed runs a Fox Podium X shock with Teixeira linkage, giving almost two inches more wheel travel. An RPM axle bumps the rear width up to the MX maximum of 50 inches.

Brand-new CST Ablaze sand tires are used front and rear, which Ed feels don't add any weight compared to stock. As you see in the pics, the rear slides easily and straight-line hookup is also good. I've had some bad luck with other dual-ribbed front tires grabbing unexpectedly on my KTM, but the CSTs are very predictable on this Honda, even with its quicker-caster setting, and they turn precisely. Wheels and bead locks are DWT A5s, hubs are Teixeira.
Honda’s 2006 and later swingarms, which are longer and help keep the front end down during hard acceleration, will bolt directly onto a 2005 frame, like Ed’s here. For rocky desert racing, a sprocket guard is imperative. Teixeira’s version is notched to get traction on whatever you might get hung up on.

Overall ergos and the setup on the 450 are comparable to those on my 525, which is to say very, very comfortable. The Teixeira footpegs, which provide an extremely stable platform, are new for 2013, and are an inch down, an inch back compared to stock.

"They give me more room on the quad," Ed says, "and the overall platform is angled up five degrees, to match the ergonomics of the rider's foot. This is in addition to the kicked-up ends at the outside of the pegs. The design is chromoly, with stainless steel teeth, which won't rust. Overall weight isn't much more than stock."

I was surprised how smooth and easy Ed's manual clutch operates, even compared to my KTM's hydraulic clutch. Ed says this is due, in part, to a tiny bearing on the ASV lever where the cable connects to it.
Teixeira's anti-vibe steering stem, with Precision bar clamps, raises the handlebars one inch, which Ed says is easier on his back. Teixeira's chromed steering stem makes steering smoother, as does a Precision RP Pro steering stabilizer. For sand, Ed sets his one click softer than mid position. Ed says that the stabilizer (really a small shock absorber) helps prevent the front wheels from getting yanked around by deep sand ruts, and then the bars from getting yanked out of your hands. Steering is still easy, because the stabilizer doesn't engage until the bars take a quick, hard jolt.
