Yamaha YFZ450R / YFZ450X

We are extremely excited to introduce our all-new High Clearance Yamaha YFZ450R XC A-arms!

We took every recommendation from our top racers as well as any complaints we've received from them and all other customers, piled it all together and built what we believe to be the best set of XC a-arms available for the YFZ450R. 

Here is what we came up!

• We kept the same geometry as the old-style DC-Pro's with the same XC width of -1 1/8" narrower per side with no forward placement. So there's no need to modify your shock tuning. Customers that are switching over from Houser arms will also be able to reuse their same shocks.
• Completely redesigned the lower arm to feature an entirely boxed in shock mount while also including a high clearance bend to achieve maximum ground clearance. That means the bottom of your shock is safe from everything on the trail as are the arms themselves.
• We got rid of all of the pivot bearings and delrin bushings and replaced them with our new greasable Polyurethane bushings in order to extend service intervals (these bushings last an insanely long time) and provide extra cushion between the trail and the rider as the poly bushings have more give compared to delrin or bearings
• Arms are made out of 4130 Chromoly and are completely tig welded
• Still requires the use of a 20" extended length shock
• The weight of these new arms is the exact same as the old style, so you are gaining more strength while not adding any additional weight.
• Shock mount has clearance for all aftermarket shocks
• Kit still includes our tried-and-true caster corrector bracket, and caster spacers
• We are also now including dust caps for the lower shock bolt to prevent mud from building up inside.

Please notice that this is a pre order for the new arms and that we are hoping to start production on these by the end of January. Feel free to give us a call at 480-834-2990 if you have any other questions or want to place an order over the phone!

We've kept our OG LSR look that you guys are used to seeing on our nerf bars with the pointed tip, but don't let that fool you, these are not the same nerf bars in any way, shape, or form.

We took every recommendation from our top racers and any complaints we've received from our customers, piled it all together and built what we believe is the best set of nerf bars available. 

Here is what we came up with for the Gen 3's!

• We kept the massive 1.66" OD 6061 aluminum main hoop.
• We've added a built-in heel guard using 1.31" OD 6061 aluminum tubing. This makes for a much larger heel guard overall for more foot room as well as decreased weight over the chromoly steel heel guard that they used to have.
• Completely redesigned the net mounts to a simple double loop design with teeth. This makes removing and installing the nets a breeze as well as cleans up the whole look of nerf bars by having much smaller net mounts. 
• The net mounts on the footpeg are also a double loop design through a plate that gets bolted to the foot peg and locks the nets in place by tightening of the bolts. This is a key feature for XC racers who are tired of banging the foot peg on a rock and rendering their nerf bars useless as they can no longer replace the nets. Since the design is less bulky, you'll have less chance of hitting them, but should you ever smash them you can simply replace the bolt on piece rather than the whole nerf bar. 
• Redesigned foot pegs that are now made out of stainless steel, so you don't have to powder coat them and they won't rust. We've increased the foot peg size to 12" long and 2 1/2" wide with a big kick up at the end to keep your feet planted. Foot pegs also no longer have middle teeth in order to aid in easy flushing of mud and dirt to ensure your boots have the most grip possible on the pegs.
  
• Increased inner diameter size on the tube underneath the foot peg for more strength.
• Additional gusseting behind the foot pegs to keep from bending/breaking when hit.
• Completely redesigned front mount to increase simplicity and save weight.

These Precision Steering stabilizers have full adjustability, impact damping, and full billet mounting for superior strength.

Pro Model has a built in reservoir to allow for thermal expansion and a stronger linkage, stem clamp, and lever.

Elite Model has all the same great features with 60% better impact damping and larger wear surfaces.

• Adjust the center stiffer than the sides or the sides stiffer than the center. Whether you prefer 10% firmer or 50% the range is huge!
• If conditions are slippery or loose: Firm up the center and soften up the sides. This will help you steer into your slide quicker and then the stabilizer will catch the back of the quad as it goes toward center reducing fishtailing.
• Want more stability when going fast and straight and less resistance when turning? You can easily tune the Precision Stabilizer to your liking.

The Shock & Vibe acts as suspension for your handlebars. The Quad's frame moves up and down and pitches left to right while the bars are suspended by the Shock & Vibe Clamp.

This gives the feel, from the rider’s perspective, that the bars are not moving, but are staying parallel to the course.

Without the bars being jerked, the quad's movement is felt in the foot-pegs as the quad kicks left to right.

This allows the rider to keep balance and position over the quad by just lifting a leg as the peg rises.

• If purchased for LSR stem it will come with anti-vibe hardware to make it work.

This spacer must be used when combining our DC-4 or DC-PRO arms with a Precision Racing Steering stabilizer. It will give proper clearance between the upper a-arm and the stabilizer.

• Comes with 4 longer bolts.

The Stage 1 is our most accessible entry-level shock model designed to upgrade your ATV’s suspension beyond the capabilities of the stock shocks

If you believe that your stock shocks are “good enough”, you probably never tried a set of properly calibrated aftermarket shocks. It is amazing how much difference our Stage 1 can make on your ATV. Even if you just cruise along at moderate speed, these shocks will erase the bumps and get rid of the vibration so you can ride comfortably and in perfect control. However, the more you press the throttle, the more your Stage 1 shocks will come alive and make a night-and-day difference to the handling and performance of your ATV.

STAGE 1 // BENEFITS

• To upgrade or replace stock shocks, often at a comparable price to OEM shocks
• Our most accessible entry-level model
• Simple to use, bolt-on upgrade for improved handling, stability and comfort
• Vehicle-specific tuning, calibrated for your personal weight and type of riding
• Same quality components and careful craftsmanship as our higher-end models
