YFZ450R High Clearance XC A-Arms

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.

Yamaha YFZ450R/YFZ450X DC-PRO GEN III Nerf Bars W/Built in Heel Guards

Yamaha YFZ450R/YFZ450X DC-PRO GEN III Nerf Bars W/Built in Heel Guards

$700.00

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.

Yamaha YFZ450R Rotor Guard Gen 2

$245.00

Shipping calculated at checkout.

2009+ Yamaha YFZ R Rotor Guard. Completely redesigned from the top down, compared to the previous product iteration. We wanted to take a new approach to what a "wear item" should be after looking at what the industry currently offers. Our thoughts are, why buy two or three knowing they have to be replaced, when you can buy one and have the confidence it will last! This new rotor guard is manufactured from the same material as our legendary Axcalibar axle for maximum corrosion resistance against those deep muddy conditions! But we didn't stop there! This rotor guard has been heat treated for superior strength and hardness to withstand the toughest conditions you can throw at it. No matter if it's rocks, roots, or ruts, it will keep your rotor protected and your brakes consistent for well beyond anything else out there! It utilizes oversized gusseting for improved rigidity, and counterbored mounting holes to protect the bolts from sheering off against rock strikes. Comes standard with grade 10.9 6mm bolts, but the mounting holes are oversized to 8mm for those that want to drill and tap their swing arm for the larger 8mm bolt diameter. Offered in Raw, heat treated stainless color (recommended), Semi-Gloss Black, or Custom Color of your choosing.
