Holz Suspension & Fox Shocks for Project Kicker Honda TRX450R

This machine is well powered and the suspension combination compliments it nicely

Suspension - it was about time we addressed this issue, especially considering all the new-found power that we gained with the new engine combo (http://atv.off-road.com/atv/article/articleDetail.jsp?id=367543&ref=25 ).

I was eager to get the components on this animal so we could see how they would all work together. Being from the Northwest, a great option for aftermarket suspension products happens to be practically right out my back door. Holz Racing Products in Linden WA happens to build some of the finest parts on the market today. Founder Mark Holz has a long history of building top notch racing products for a variety of motor sports. The name is synonymous with winning in the snowmobile industry, and for the last several years, HRP has been focusing a tremendous effort on their line of products for ATV’s.

Basically, set up of a WORCS bike is the same as MX except, you need a little more ground clearance. So we opted for the HRP +2 ½ “ A-arms. This puts the width of the quad out to full 50” with the use of 4-1 offset wheels. This kit comes with A-arms, adjustable camber, replaceable high-quality, heavy duty PFTE lined stainless steel ball joints, 2 1/2" added travel over stock with 18 3/4" shock, sealed wear-resistant delrin pivot bushings with greasable hard coated pivot sleeves and a variety of color options to choose from.

Next it was time for shocks, and this is were it gets really cool. The shocks that went on this bike are just about in a league of their own. None other than the Fox Float X Evols up front and the Podium X on the rear. These shocks are pretty unbelievable. The Evol fronts are what all the buzz is about. They have no external coil over springs, so the job of the springs is done internally by air. They have two air chambers - the main chamber and the Evol chamber. These two air chambers with each other to ultimately give you the plushest ride you can imagine (and then some) in the choppy stuff and the bumps, but still can handle the big hits with ease. Each set of Evols comes with two air pumps - one high pressure and one low. And with these pumps you can pretty much revalve your shocks in the pits or whereever you may be in a matter of minutes. In addition to the air adjustments they also have the traditional compression and rebound adjusters. So with all the adjustability of these shocks a person can get a customized ride for virtually any type of riding or track condition. My suggestion, as with any shock, always take good notes so that you can track your changes for specific conditions. Not to mention if you make a bad change it's much easier to get back to where you started from.

This machine is well powered and the suspension combination compliments it nicely. The A-arms feed back minimal bump steer and added travel is great for the big hits and the rough stuff.

Speaking of rough stuff, the front shocks almost get that part out of the equation. They are pretty much unlike any shocks you have ever ridden on. They are nearly half the weight and it is definitely noticeable in the front end while riding. They are very progressive as well so the nasty choppy breaking bumps are something you can just roll through and they still have plenty left over to soak up the big hits. The more I ride on these shocks the more I like them. Adjusting them does take a little trial and error. But like I said before if you keep a good log of what you are doing then you will get the hang of it a lot faster.
