Testing the TEAM driven clutch on a prototype ZR4000RR.
Arctic Cat updated the 2015 ZR4000RR with new race-focused features aimed at higher performance and improved handling.
Topping the list is the addition of the TEAM TSS-04 driven clutch that replaces the Arctic Cat clutch.
Arctic Cat used the TEAM driven clutch in the 2010-2014 Sno Pro 500 snowmobile that the new 4000RR replaces for this coming season.
In fact, Arctic Cat cited the excellent results shown on the racetrack and an abundance of tuning components available for the TEAM driven as two reasons for the change on the ZR4000RR.
The ZR4000RR also gets a new splined jackshaft to accept the TEAM driven.
The second major update on the 2015 ZR4000RR is longer A-arms for a wider 43.5-in. (center-to-center when measuring from carbide to carbide) ski stance, the maximum width allowed under ISR rules.
A new 5-in. Trail Ski featuring a single-runner carbide will be utilized to stay within the 48-in. maximum width (when measured between the outsides of both skis) allowed in certain states. The top of the new ski also features added structural “webbing” for increased stiffness.
These updates will ensure the new ZR4000RR is even more competitive in cross-country and snocross.
