1998 SKI DOO Snowmobiles

HIGH PERFORMANCE SPORT

PURPLE SCREAMERS HANDLE BETTER, LOOK MEANER

High performance sport riders take to flat trails at high speeds and expect their triple-cylinder snowmobiles to deliver smooth, strong acceleration and an abundance of power in a good looking, well-built package. They're serious enthusiasts, price-conscious. For 1998, the Ski-Doo Formula III sleds deliver, and in the new CK3 chassis, set new standards in triple-cylinder sled  handling.

 

FORMULA III FEATURES

Rotax triple-cylinder engines. The heart of the segment? Two Rotax' three-cylinder engines: the 599 baby triple in the Formula III 600 and Formula III 600 LT sleds, and the 699 in the Formula III 700 sled. The 599 engine powered Mike Houle and Normand Pilote to dozens of F-III racing victories, including four season championships over the past two years, and Houte's 1996 and 1997 Eagle River World's Championships. Both powerplants feature crankcase reed induction with an intake resonator and exclusive R.A.V.E. exhaust port modifiers. Three central-outlet tuned pipes are standard.

SC-10 High Performance rear suspensions
Aggressive trail riding requires comfortable, yet taut suspensions. The SC-10 High Performance rear suspension, equipped with High Pressure Gas (HPG) or Motion Control gas shocks, makes for a comfortable, stable and responsive ride on any trail, Its patented Acceleration and Control Modulator (ACM) improves handling by increasing ski pressure when powering out of corners. It's also adjustable so the rider can set their desired mix of cornering and acceleration. A softened track angle for '98 makes for higher top-end speeds.

DSA front suspensions
Improving handling at all speeds was a primary objective of the CK3 project. The DSA trailing-arm front suspension was completely reworked and now utilizes an unequal-length radius rod design for zero bump steer and scrub. New steering system components and positioning make steering easier. Plastic skis - narrow on the FIII 600 and 700 models, wide on the FIII 600 LT model offer good bite and shed snow easily.

TRA clutch
Labeled bulletproof for its legendary reliability, the TRA delivers power to the track with efficiency. Riders can easily adjust the maximum rpm setting on the TRA without disassembly.

Bombardier hydraulic disc brake
Smooth, progressive-feeling stopping power. Self-adjusting for pad wear.

All-new features
Digital Encoded Security System (DESS) for increased theft protection, electronic white-face gauge cluster with LCD odometer reads in either miles or kilometers with the push of a button. A new single clear-lens headlight, with dual 60 Watt lamps and dual multi-facetted reflectors, produces double the candlepower of the '97 Lamp.

MACH MUSCLESLEDS PUSH TECHNOLOGY ENVELOPE

When it comes to the "need for speed" on the lakes, muscle riders have the greatest needs. But being hard-core snowmobile enthusiasts, they also require their sleds to handle stable and precise on the trails. In the past, triple-cylinder power and precise handling were often mutually exclusive.

How? With the new CK3" triple-cylinder platform. Nearly four years in the making, the CK3 sets new standards in MUSCLE SLEDS looks, handling and performance, and many improvements have been made to set new standards in fit and finish.

MACH  FEATURES

Rotax" triple-cylinder engines
Painstaking craftsmanship, innovative design and engineering make these Rotax triples the most powerful and reliable in the industry. Crankcase reed induction, complete with intake resonator, feeds these liquid-cooled beasts. Exclusive R.A.VE. exhaust port modifiers provide more response and torque in the low- and mid-rpm ranges while still pulling class-leading top-end speeds. Three central-outlet tuned pipes are standard.

SC-10 High Performance rear suspensions
Aggressive trail riding requires pliable, yet taut suspensions and straightlining requires efficient track hook-up. The rising-rate SC-10 High Performance fits the bill. It's complete with ACM, an adjustable back-to-front suspension coupler which makes the sled sit flatter to the trail during acceleration, increasing ski pressure.The track angle is revised for higher top speeds and top-of-the-line High Pressure gas (HPG) shocks (Motion Control gas shocks on the Mach Z LT sled) provide absorption.

DSA front suspensions
Reworked for the CK3 project, the DSA trailing-arm front suspension now features an unequal-length radius rod design for zero bump steer and scrub. HPG shocks on both the Mach Z and Mach 1 models soak up the bumps with fade-resistant performance. The Mach Z LT sled uses Motion Control gas shocks. A new easier-to-steer system debuts and narrow plastic skis are standard.

TRA clutch
Labeled "bulletproof' for its legendary reliability, the TRA delivers power to the track with efficiency. Riders can easily adjust the maximum rpm setting on the TRA without disassembly.

Bombardier hydraulic disc brake
Smooth, progressive-feeling stopping power. Self-adjusting for pad wear.

All-new features
Digital Encoded Security System (DESS) for increased theft protection, electronic white-face gauge cluster with LCD odometer reads in either miles or kilometers with just the push of a button. Dual single lens/multi-faceted reflector headlamps produce double the candlepower of the '97 lamp.
