While the Adrenaline model may lack some of the БЂњXБЂ« package enhancements, all MXZ models come with strong fundamentals. The REV-XP aluminum chassis is both light and strong. The runningboards open style footing not only provides ample grip for snowboots, but helps dispatch snow so it doesnБЂ™t hang up in the suspension. The pioneering REV rider-friendly position evolved for more comfort and function in this latest chassis design, making the MXZ Adrenaline one of the most fun sleds to b

Like the more expensive X-model, the MXZ Adrenaline delivers up to 15-inches of rear suspension travel and nine inches of travel from the double A-arm front end. With a ski stance of 42.4-inches, the 432-lb MXZ Adrenaline handles corners with exceptional bite. You control steering inputs from a handlebar modified with J-hooks on the ends. Even though the hooks extend your hand placement outward, the mid-height windshield features flared sides to direct air away from your hands.

DonБЂ™t get us wrong; the base Adrenaline gets good shocks. But there is a difference. The standard Adrenaline comes with high-pressure gas shocks that are made by KYB. The lightweight and revalvable, aluminum shock will resist fade and will be fine for most Adrenaline owners. But the X shock package goes one better as its KYB-manufactured HPG Plus R aluminum shocks feature an external knob to adjust rebound action. ThereБЂ™s a similar performance difference on the rear SC-5 slide rail suspension as well. YouБЂ™ll find steel-bodied HPG shocks fitted on the AdrenalineБЂ™s rear suspension arms. The БЂњXБЂ« package adds the aluminum-bodied HPG Plus to the front arm and a KYB Pro 36 that features aluminum construction and a high/low speed compression adjustment so the rider can fine-tune the suspensionБЂ™s bump response.

The 2010 Ski-Doo MXZ Adrenaline 800R PowerT.E.K. remains a popular option for sport sled riders. Given its power to weight performance, the MXZ Adrenaline comes in a mere five pounds heavier than the early-season БЂњXБЂ« package which will make it a top performance sled in this БЂњ800БЂ« sport category. LetБЂ™s face it though, opting for the БЂњin-seasonБЂ« MXZ means that you do give up some higher-grade shocks at the front and on the rear suspension. You also give up the 1.25-inch lug profile on the БЂњXБЂ« models as the AdrenalineБЂ™s lightweight Ripsaw track profile measures an inch in height. Frankly, only extremely serious trail shredders will notice the difference. However, we expect that difference in shocks to be noticeable and a good reason for opting in early on the БЂњXБЂ« package.

WeБЂ™ll keep from getting too negative on the PowerT.E.K. twin because we suspect a new 800cc E-TEC version may be on the horizon. Heck, many of us snowmo-writers expected to see an 800 E-TEC joining the popular 600 E-TEC in model year 2010. The fact that it didnБЂ™t happen may be due to the overall economic travails hitting the entire powersports industry right now. If you take a close look at this seasonБЂ™s overall snowmobile product line, youБЂ™ll see few all-new models. Instead, companies have updated their product offerings.

There is no 4-stroke option with the Adrenaline package as there was with the early-season БЂњXБЂ« choices, but you can amp your ride with the 800cc PowerT.E.K. twin that Ski-Doo claims makes 151-hp. While we favor the Rotax 800 ahead of PolarisБЂ™ Liberty 800, neither is as smooth as Arctic CatБЂ™s equally powerful but eminently smoother 800. Besides the somewhat peaky power of the Rotax twin, we found the heavy pull of its dual Mikuni 40mm carburetors lacking in rider-friendliness. At this point in sled development, how about some lighter thumb pull by adding electronic fuel injection? Yeah, we appreciate that owners of these big twins are more apt to boost power by modifying the motor, but how about the rambunctious rider who wants stock go-fast combined with easy riding?

positions its Adrenaline model as the sport sled for the rest of us. The rest of us being those who didnБЂ™t make a purchasing decision early enough to set aside either the X-RS racer-performance model or an БЂњXБЂ« model. But, left to the БЂњin-seasonБЂ« choice of a 2010 MXZ Adrenaline, we wonБЂ™t suffer too much.
