TEAM Drive and Driven Clutches
The Arctic Drive System features Team Rapid Response II drive and Rapid Reaction BOSS driven clutch combination for smooth shifting, optimal performance, maximum durability; and reduced weight. The Rapid Response II drive clutch features a roller bearing on the shaft that enables an auto-adjusting belt tension design and delivers consistent performance without manual adjustments. It also features a 12.5 percent lower effective starting ratio (while maintaining the top ratio) for smoother engagement and reduced belt wear at drive-away speed, with more evenly distributed force for lower belt pressure. It’s a design that’s unique to Arctic Cat. The Rapid Reaction BOSS driven clutch features the Built On Shaft Secondary design, in which the clutch is designed with machined sheaves that mount directly to the machined-matched driven shaft. Unique to Arctic Cat, BOSS eliminates the need for the steel clutch post in traditional designs, saving weight, reducing rotating mass, improving clutch balance and achieving tighter clutch/shaft mounting tolerance. In addition to the benefits of BOSS, the Rapid Reaction driven clutch features optimized cooling fin geometry that results in low clutch and belt temperatures for improved belt life and performance. The Rapid Reaction BOSS is also 0.25 lbs. lighter than previous designs, resulting in quicker acceleration.
Stealth Lightweight Master Cylinder Brake System
New for 2019, the Stealth lightweight master cylinder brake system with a new lever design delivers increased braking power with less required force compared to the previous design. The dual-piston caliper is positioned with the rotor so that any chassis flex won’t knock back the pistons. Reduced knockback allows smaller caliper pistons and a shortened lever “throw” before the pads contact the rotor, which enables more powerful braking pressure. The new master cylinder is more protected and robust than the previous design, and is less likely to be damaged in extreme situations. The new lever shape is more ergonomically comfortable, and its composite construction feels warmer compared to aluminum levers. All 6000 and 8000 M series models utilize a lightweight disc/caliper/pad system, as well as the drilled race version brake disc.
