Gravity LED Pro6 Light Bar: Assault YZX1000R AKA “YXZari”
“Ever since the Yamaha YXZ1000R’s debut in September of 2015, the machine has been a hot-ticket item for riders and parts manufacturers alike. Fields of Polaris RZRs are now punctuated by the triple-cylinder machines, and they boast components from many different companies, like Assault Industries. Assault turned a 2016 Yamaha YXZ1000R Special Edition into something even more exceptional than the stock Japanese-made UTV.”
WHEN IN DOUBT, POWER OUT
Assault Industries branded their customized Yamaha the “YXZari.” Ferrari is known for creating sleek, top-performance supercars that are built for one thing—speed. The YXZari has taken a few pages from the Italian supercar book when upgrading the power output of the Yamaha.
The Yamaha YXZ1000R three-cylinder, four-stroke engine has a unique exhaust tone reminiscent of a Ferrari. The YXZari gained a custom-made Burns exhaust system that delivers a high-performance riff to your ears while helping increase power with a higher flow. The pipe was a one-off to add to the YFZari feel. An assortment of DynoJet parts were installed on the Yamaha to control the internal and external power upgrades. A Power Commander PC V now helps control the fuel-injection mapping of the engine. The PC V is paired with an ignition module to control the ignition timing and curve. Assault Industries also installed Power Commander’s Autotune system that utilizes O2 sensors on the exhaust system to allow mapping changes of each cylinder separately and simultaneously. Power Commander’s Pod is an interface that allows you to easily control and adjust aspects of the Yamaha’s fuel-injection system and ignition system to give the machine a proper air-to-fuel ratio for a stronger power output.
The YXZ1000R’s suspension does one thing very well: it handles high-speed whoop sections like no other. The shocks perform well in most situations that are very fast paced, but the rear shocks tend to buck over jumps, and the machine is a rough ride at slower speeds. The most noticeable upgrade when we first drove the YXZari was the Elka Stage 5 shocks. They soaked up slow-speed chop in a much smoother manner, which provides a better ride for the average trail rider or recreational driver. The Elkas also soaked up high-speed hits better than the stockers, and the rear shocks didn’t buck over jumps, which is great for a fast driver or racer. The Elkas changed the handling characteristics of the YXZ from a Corvette to an extremely well-dialed-in ride like a Ferrari.
VISION UPGRADE BY KC HILITES
Vision is very important in off-roading, and Assault Industries knows this quite well. They installed an over-the-top lighting setup from KC Hilites that includes two A-pillar-mounted dual Flex LED lights, a 10-inch LED light bar mounted to the front bumper, and Pro6 LED Light Bar mounted in a spread on the roof of the YXZ. This system called for a Yamaha alternator kit and an XTC power-control harness to tackle the lighting duties. Assault installed two light-switch mounts that they make for the machine.
This Yamaha has been fitted with a bunch of products from Assault Industries, including a custom roll cage that is designed to be more protective in a rollover compared to stock. The safety features don’t stop there. Five-point harnesses were installed that are certified for racing, and a front and full rear bumper were added to the YXZari. The Assault team installed its Bomber-series side-view mirrors, along with its Stealth-series center rear-view mirror. A quick-release fire extinguisher was also fitted to the roll cage of the Yamaha. A new product that Assault recently released is their Hydration door bags, which readily provides water with a tube, like a hydration backpack, and extra storage for the doors.
