Soft bars by ATV Four Play

We're using a lot of brand-new products on the TPR project YFZ450R motocross build, including a set of Soft Bars from ATV Four Play.

A set of ATV Four Play's Generation II Soft Bars adorns the TPR project YFZ450R.

ATV Four Play has helped win countless championships with their a-arms. They clearly know how ATV suspension should work. So it made perfect sense to complement the MGC MX long-travel a-arms we're using with a set of their new Soft Bars. The bars were introduced last year to help cushion the hard impacts motocross riding can deal to a racer's upper body.

The bars work much like your typical quad shock. An allen-head bolt can be tightened or loosened to stiffen or soften the bar travel on each side. The bushings used are a cone-shaped polyurethane. The Progressive Dampening System ensures the resistance increases the more you tighten the allen head and as the bar moves through its travel - just like an ATV shock.

The Soft Bars are designed to mount directly to an aftermarket steering stem. In addition, ATV Four Play offers two more bar sets with differing mount positions in order to fit the stock Yamaha YFZ450R stem and the stock KTM stem.

The view from overhead shows the 12-degree bar sweep, which feels very comfortable and is similar to the CR high bend bar.

The Soft Bars are made of T-3 2024 aluminum tubing and billet T-6 6061 aluminum. The pivot areas are sealed, but one great aspect of the bars is they feature grease zircs to maintain the life of the pivot bushing. The bars retail for $295.

ATV Four Play's Generation II Soft Bars - quad engineering at its best!

We haven't ridden the TPR project YFZ450R on a motocross track yet to provide a review of the bars, but we'll be getting ready to conduct our test video with ATVOnDemand.com hopefully in the next few weeks. And ATV.com will be running a series of stories on the project quad, including a complete ride review, this fall.

Our next post will feature the Tarantula Performance Racing MX-Series front bumper and a set of TPR's new Race Safer nerf bar and heel guard combo. Stay tuned...
