A mere mention of the ZR name and snowmobilers know of its legendary winning ways. Riders needing 165-class horsepower can look to two performance-built ZRs with a variety of options for 2022 – the ZR 8000 Limited and ZR 8000 RR.
Each is powered by the C-TEC2 794cc twin-cylinder engine, delivers clean responsive performance with leading fuel economy thanks to DSI, Electronic APV Exhaust Valves, Exhaust Pipe Temperature Sensor, electric oil injection, ceramic exhaust and convenience of push-button engine reverse and electric start.
Championship-winning power, smoothness and reliability is backed by the all-new Arctic Cat ADAPT CVT System. New Drive and Driven clutches are lighter-weight and employ a compact design with advanced idler system. ADAPT maintains constant belt tension throughout the RPM range resulting in minimized wear and maximum throttle response throughout your drive belts longer life without fade.
Stout engine and clutching performance is matched by the race-proven ProCross chassis delivering an ultra-rigid platform and optimal riding position. Up front, the Arctic Race Suspension (ARS II) offers 9-in. of bump-eating travel, while the coupled 137-in. SLIDE-ACTION Rear Suspension boasts 13.5-in. The ZR 8000 employs the Ripsaw II track with 1.25-in. lugs for a masterful blend of speed and traction.
The ZR 8000 Limited has choice of two different suspension packages – the first is a moderately aggressive suspension calibration with manually activated FOX 1.5 ZERO QS3 ski shocks. In the rear are Arctic Cat IFP 1.5 front- and FOX 2.0 ZERO QS3 rear-track shocks.
Limited riders looking for the ultimate level of premium rider performance can opt for the ATAC adjust on-the-fly suspension system. The innovative ATAC utilizes a thumb-operated button on the left handlebar controls to operate the FOX ZERO iQS3 ski and the rear track shocks, allowing the rider to instantly switch between three factory compression settings (Soft, Medium and Firm), with two additional settings (Driver 1 and Driver 2) allowing you to customize your own calibrations between front and rear shocks.
Deluxe Digital gauge, push-button electric start, LED headlight and 11-in. mid-height windshield are standard features on the ZR 8000.
The ZR 8000 RR is a no-compromise cross-country race-replica aimed at the big bumps, with championship-winning features including competition-calibrated components like the front FOX 1.5 ZERO QS3R ski shocks providing quick adjustability, a premium Kashima coating and rebound dial. The rear suspension gets the same shock treatment – FOX 1.5 ZERO QS3 front- and FOX 2.0 ZERO QS3R rear-track shocks both with Kashima coating. Rounding out the RR features are push-button electric start, LED headlight, hand guards and a 5.5-in. race-height windshield.
The performance-inspired bodywork comes in Green (8000 and 8000 RR) or Orange (8000 Only) and includes a commemorative 60th anniversary badge.
Snowmageddon Ordering and Accessory Kit
During the Snowmageddon Order period you’ll get your best deal of the season. All ZR 8000 models are available in Green (8000 Limited and 8000 RR) or Orange (8000 Limited Only) with an Accessory Trail Blazer Kit option including Pro front bumper, handlebar bag, large rear storage trail pack and taller 15-in. mid touring windshield.
ADAPT CLUTCHING INTERVIEW WITH KYLE OLASON – MECHANICAL ENGINEER, DRIVETRAIN DESIGN
Alot of you have asked for more information on the new ADAPT drive and driven clutches on full-size 2022 models. I got a chance to sit down with Kyle Olason, mechanical engineer in the Arctic Cat Drivetrain Design Group to ask a few questions.
AI: Kyle, what is ADAPT?
Kyle: ADAPT refers to the new CVT system as a whole (drive and driven clutches, and belt). The biggest innovation focused on the drive clutch which we’ll get into. The drive belt is carry-over from Model Year 2021 models. Driven clutch, while new, retains similar mounting and system to current production.
AI: Why ADAPT?
Kyle: The new clutch system is an effort to internalize the design of a critical component within our vehicles. The new system retains the idler bearing method for automatic belt tension which debuted on the MY17 9000-series snowmobiles and MY18 6000+ series snowmobiles. When bringing the design back to Arctic Cat, there were opportunities to get creative.
AI: And those opportunities to get “creative” were what?
Kyle: This is a three-fold answer:
1. Our past solutions in the drive clutch have had the torque transfer buttons aligned with the cam arms, and this set a parameter of minimum width possible for the moveable sheave. By moving the torque transfer to a different location from the cam arm/roller, the width of the clutch became a focus to utilize space more efficiently.
2. Concepts showed moving the cam arm radially outward from past designs would allow the spring to nest deeper within the spider.
3. Unique spider design allows for the spring to nest inside much of it while transferring torque and reacting to the cam arm load.
AI: And the benefits were what?
Kyle: While it started off as a study of “What is possible”, much of the unique aspects were able to be retained.
1. 1lb. lighter than current production
2. 5% reduction in inertia
3. Compact design with ~25mm or 14.1% reduction in width
4. Our goal related to belt life is to keep performance from our current product. We have had good belt life with our MY21-previous system. The idler drive system ensures the belt deflection is consistent throughout life while maintaining that low starting ratio.
5. Maintenance: The goal is zero-to-minimal service. The pocket in the spider above the cam arm can make inspecting for wear easier
AI: Will ADAPT retrofit to past models?
Kyle: Yes. Consumers wishing to retrofit ADAPT will have the opportunity this Fall when available.
AI: Will ADAPT add any top speed?
Kyle: You’ll see a quicker throttle response and acceleration
AI: Thank you for taking the time to answer a few questions. I appreciate it.
Kyle: You’re welcome!
