YFZ450R Adjustable Upper A-Arms by Teixeira Tech Test Review: The Best Upgrade for The YFZ450R? Teixeira Tech is a bit of a high end boutique brand offering a surprising amount of value for the price. Teixeira Tech’s A-Arms are built in the United States of tig welded 4130 chromoly. Just like Teixeira’s full set of XGC arms, their CXC upper A-Arms add camber and caster adjustment to the YFZ’s front end. Teixeira's caster adjustment system is simple and intuitive. The notched system can be loosened up, adjusted and tightened in a couple of minutes. This makes optimizing handling easy for riding in tighter or wide open conditions.

The included Caster Bracket eliminate the YFZ450R’s caster increase with their Caster Bracket that raises the rear of the A-Arm making it more in line with the angle of the lower Arms. Teixeira tells us that you can’t make the upper and lower A-Arms perfectly parallel with the lowers. For this reason, Teixeira Tech’s Caster Bracket slightly overshoots parallel, which causes caster to slightly decrease as the front end compresses. This allows the machine to turn in slightly quicker with less effort and bump feedback through the bars.

Having ridden them, we’d go as far as to say that Teixeira Tech’s CXC A-Arms are a must have upgrade for any YFZ450R owner looking to maximize performance for the least amount of money. For many of us, the YFZ450R’s 48.5” width and 9.8” of front suspension travel is plenty. Teixeira Tech’s CXC upper arms undoubtedly improve handling and offer all the adjustment of a full set of aftermarket A-Arms at a fraction of the price. Best of all, since they don’t change any leverage ratios on the front end they don’t require you to spend any added money on your shocks until you’re ready to take that next step.

A good steering stabilizer is a mandatory handling upgrade for any sport ATV owner. As is a set of A-Arms with Teixeira Tech’s Castor Bracket if you happen to own a YFZ450R.
