Yamaha strikes back in the UTV and side-by-side segment with its pure sport, three-cylinder and manual gearbox-powered YXZ 1000R. Yamaha’s all-new YXZ is designed for off-road thrill seekers that want the utmost in performance and durability.

POWERTRAIN

The YXZ borrows engine architecture from Yamaha’s snow sport department sourcing a four-stroke and water-cooled 998cc Inline Three positioned at the rear of the vehicle. The engine gets a few enhancements specifically for the rigors of an off-road car.

The YXZ borrows engine architecture from Yamaha’s snow sport department sourcing a four-stroke and water-cooled 998cc Inline Three positioned at the rear of the vehicle. The engine gets a few enhancements specifically for the rigors of an off-road car.

Inside, the YXZ gets its own camshaft profiles giving it a broader powerband through its 10,500 rpm rev range, especially at lower rpms. A single-axis counter balance mounts to the crankshaft and is claimed to reduce engine vibration by 25% at 8500 rpm. Furthermore, the top of the cylinder case has an ‘anti-vibration bolt’ to further reduce bad vibes.

To keep the size of the engine as compact as possible, the YXZ features a dry sump lubrication system (baffled aluminum container located mid-cab, behind the passenger seat) allowing for a shorter oil pan without compromising capacity and/or cooling capability. A dual-stage intake air filtration box uses a foam primary filter and a smaller paper element to trap finer debris boosting maintenance intervals. Five quick-turn fasteners behind the cab allow access to the airbox.

A sequential five-speed manual transmission, with reverse (shifter mounted on the floor) mates to the front of the engine and is augmented via hydraulically-actuated foot-pedal clutch. The YXZ also uses an ‘On-Command’ four-wheel drive system. A three mode toggle switch includes rear wheel drive (2WD), four-wheel drive, as well as a front differential lock setting which gives true four-wheel drive, say for rock crawling, etc.

CHASSISThe YXZ is underpinned by a tubular steel frame with a cleverly designed independent suspension system. Specifically, the A-Arms are mounted at an angle promoting stability (with minimal tire camber change through suspension stroke) by moving suspension impact loads from front-to-rear, and vice-versa, as opposed to side-to-side. Front and rear sway bars are also fitted to keep the car flat through turns. A rack-and-pinion steering system, with electronic power steering (and tilt steering wheel position) is also standard.

Fox Podium 2.5 shocks were sourced and valved to Yamaha specification. The front coils are 26-inches in length (eyelet-to-eyelet) with 16.2-inches of movement. The rears measure 32-inches with 17-inches of stroke. Both shocks use progressive-rate coil springs to help give the driver the best of both worlds: everyday comfort and sport performance.

Automotive-style and hydraulic four-wheel disc brakes, with an independent disc parking brake keep speed in check. The 1000R rolls on 14-inch cast aluminum wheels shod in 27-inch Maxxis Big Horn 2.0 tires.

Visibility and line-of-sight is crucial when driving on un-even terrain. So the Yamaha uses a low seat (26.4-inches) with a sharp-soap contoured hood for improved vision. Inside the cab are a pair of high-back seats with lateral support, shoulder bolsters, and adjustable handholds. A conventional three-point seat belt keeps the driver and passenger in place during rides.

Assembled in Georgia, the YXZ 1000R is available in three colorways and will arrive at U.S. dealers later this month. Furthermore, Yamaha will be offering demo rides in select cities later this fall. Expect an abbreviated passenger seat impression and video later this week.
