The 1998 Arctic Cat ZR 600 EFI was the SnowGoer Magazine Snowmobile Of The Year!. It's long list of features and new chassis design put the bright green sled over the top. It starts with the motor, a crisp-reacting 599cc twin fitted with Cat's exclusive battery-less EFI system, which provides awesome acceleration, always-accurate air-fuel mixtures and a light throttle pull, all without the extra weight of a battery. The engine also features Cat's new clutching, complete with roller secondary, a user-friendly air box and other features. The power-plant rides behind the best handling front suspension system ever developed, Cat's AWS V. This lightweight, agile front end holds its lines in corners extremely well, allowing a carve that is beyond compare. It hooks into a lightweight bulkhead that sets the tome for the whole machine - light and agile. The rear suspension is Cat's long travel FastTrack, which offers a claimed 13.5 inches of travel. The travel number is high, but the way Cat gets there is impressive, It starts with the Extra Travel Tunnel, which features a kink at the rear to allow more Suspension movement without serious tampering of the sled's center of gravity. Even more impressive is Cat's Torque Sensing Link. It counteracts the rear suspension's natural desire to squat under hard acceleration, giving maximum travel when pushed hard. The finishing work is the coup de gras. The styling focuses on both function and aesthetic appeal, from the Celstrand front bumper to the integrated skid plate, from the raised wells above the front suspension to the well-placed hand and thumb warmer switches and the blight, twin-bulb headlight. 1998 was the Year of the Cat, and this Cat is the pick of the litter.
