Mach Z Test

Ski-Doo pulls away from the performance pack
The long-awaited numbers are in, and there's no debating that Ski-Doo's lake racer is the new performance champ. Our dyno results (plus our Real World Shoot-Out, p. 16) prove the 998cc clean-burning Rotax powered machine has the horses to pull away from the performance pack.

After several test runs, our official dyno tester Rich Daly at Dyno-Port gave us the news we had anticipated… 165 hp at 7800 rpm! AmSnow dubbed the Z "Mr. Nasty" when we first rode it last spring, and it's lived up to its name and claim to produce 165 horses.

The Mach is ridiculously strong for a stock sled - it topped 160 hp from 7300 rpm all the way through the end of the power band. With that kind of attitude we had to double-check that this was a twin and not a triple!
In addition to the horses that Ski-Doo reined in, the 115 foot-pounds of torque this monster unleashes tops any current stock sled. Torque numbers held steady at over 110 ft-lbs. from 7100 rpm until the end of the pull. First time riders beware because Doo's black stallion will throw you straight back in the saddle!

When I wrote this I had put just more than 300 miles on our own semi-direct injected Mach Z test sled. The power is certainly no joke and only gets better after break-in. Even more impressive is that the sled complies with 2006 EPA regulations and rivals 4-strokes in quietness.

But this snow-rocket is not for the faint of heart, or for riders who refuse to muscle a sled around. All that dyno-proven power comes with added weight, which Ski-Doo lists at a contestable 519 lbs. With more power and weight than other REV models, those who ride the RT-platformed Mach this winter need to take extra care to respect safety regulations. Those who haven't picked up a new Mach, keep looking over your shoulder because Mr. Nasty is in town ... and gaining on you!
