NEW ADJUSTABLE WINDSHIELD FOR REV GEN4 SLEDS

BRP introduces a new Adjustable Windshield for the latest REV Gen4 platform based Ski-Doo snowmobiles that allows riders to change wind protection minute by minute.

Riders have long expressed the desire to change windshield height as they ride throughout the day.

Starting with a taller windshield during colder morning hours and being able to lower it mid-day, as temperatures climb and for better vision, is what riders are looking for.

This new kit addresses that need by moving the windshield 4 inches (10 cm) total with a unique lever system that’s both quick and secure. The range of 19″ to 23″ (48.5 to 58.5 cm) effectively moves from a medium windshield height – to that of a high windshield.

When mounted on the sled, changing height is accomplished by flipping the lever up, sliding the windshield to the desired position and then pushing the lever back down to lock it in place.

The slides the windshield moves on are robust to operate in all temperatures easily and smoothly, while the locking lever can be operated with gloves on.

Pricing is $249.99 USD/$304.99 CAD

NEW LINQ REMOVABLE SNOWFLAP OFFERS SKI-DOO DEEP SNOW RIDERS MORE PERFORMANCE

BRP is introducing a new LinQ Removable Snow Flap for 2018 that will give deep snow riders even better performance.

The ability to remove the snow flap allows snow to move more freely through a snowmobile’s tunnel, reducing drag and maintaining a rider’s momentum in deep snow.

The LinQ Removable Snow Flap lets a rider choose between the normal mounting position, for the trail ride into play areas so they can maintain proper engine cooling, or top of tunnel mounting for deep snow – where plenty of snow reaches the heat exchangers. With the unique and renowned LinQ system, changing positions is fast, easy and secure.

The kit reuses the stock snow flap and fits Summit and Freeride models built on the new REV Gen4 platform having track lengths 154-inch and longer.

Model year 2018 sleds have pre-marked tunnels and snowflaps to make installation even easier.

Pricing is $119.99 USD/$144.99 CAD

2017 XF CROSS COUNTRY LIMITED

Features

Staff Report

The XF Cross Country is a unique animal in that it bridges both trail riding and powder riding extremely well.

Although we wouldn’t call it a complete freestyler, we will vouch for its ability to handle all sorts of powder use, including some fairly aggressive climbing.

At the same time, this Cat is extremely good on trails. Its coupled back end and quick handling, hampered only by a pair of imprecise carbides, make it fun to ride and ever since Cat introduced this 137-inch track length a few years ago, it’s been one of our favorite ProCross configurations.

The Cross Country’s track and shock packages are what make it unique. We’ll take it a step further and blatantly declare this is a much better sled when you order it with a 2-stroke. Since the CC is definitely targeted at off-trail riding, weight is of the utmost importance.

Although the Yamaha 998cc turbocharged triple (9000) is very capable in powder due to its nearly limitless power, it’s way more comfortable on trails. Get it in the deep stuff and you’re usually pretty puckered with the prospect of getting it submerged.

The truth is, the new breed of crossover sleds from all OEMs needs to be slightly over-biased toward off-trail but still have strong competence on trails. Thus, choosing a fully coupled, sliding front arm skid is a stellar choice. Yes, the uncoupled 141 and 153 length tracks are really good in powder, too – actually flitting very close to a mountain sled’s potential – but the Slide Action 137 is just flat-out excellent in both applications.

Since the Cross Country uses a 1.75-inch Backcountry X track and has a full menu of Fox Zero Pro QS3 shocks (the front arm is a non-adjustable gasser) there’s absolutely no doubt you can adjust your way into a near-perfect trail ride.

Although a 1.6-inch deep track may be the ideal for trails, the 1.75 makes a huge difference off-trail and will likely survive slider wear on hard pack and won’t rip up the trails to the point snowmobile groomers will put an APB out for your sled.

Cat’s decision to move to TEAM primary and secondary clutches last year was a good one and guarantees you’ll get a good backshift in powder. It’s worth noting the Cross Country Limited has exactly the same gearing as Cat’s L-TX 137-inch trail-targeted sleds, so that underscores the benefit of Rapid Response clutching.

Back in the day, Arctic Cat’s most serious production racers were called “Cross Country Cats”. Although this one isn’t targeted specifically at cross country competition like those sleds were or even the current RR series, it has very strong potential to be loved by the above-average-skill, aggressive ditch and high speed trail rider.

BRP introduced the adjustable limiter strap for tMotion rear suspensions two years as a quick easy way to adjust deep snow handling on Summit and Freeride snowmobiles.

This year the concept is taken further to a remotely controlled system for even easier and quicker operation.

Riders benefit from being able to quickly adjust their ride between a playfully light and agile set-up, to a more connected one where the track approach angle gets much more gradual and the skis don’t lift as easily.

By making it remotely activated, the dial like switch is mounted on the handlebar riser; riders can now change positions by twisting a knob rather reaching down by their feet to flip a lever.

The kit should also prove popular with the cross-over crowd as it also fits the new cMotion rear suspension on the 2018 Backcountry models.

If a rider wants more positive steering on the trail, they can move it to the shorter position, but when going off trail -switching to the longer position will provide better deep snow handling, in a very quick and convenient way.

Adjustment range is equivalent to 2 holes on a conventional limiter strap (1.3 inches/34 mm), with 2 settings to choose from: holes three (stock position) to five, or two to four.

The kit is available for all tMotion and cMotion suspensions from 2013 – 2018 Pricing is $269.99 USD/$329.99 CAD

Polaris snocross racer Kody Kamm (Hentges Racing) won six straight heat races and two of three Pro Open finals at the ISOC season finale in Lake Geneva, Wis., to win the 2016-2017 Pro Open championship. Kamm earned an incredible 174 of 177 available points, finishing with 799 points and winning the title by 13.

Polaris Racer Elina Ohman (Davies Racing) won the ISOC Pro-Am Women’s points title, and Jake Angove (Judnick Motorsports) finished second in Pro Lite points.

Kamm entered the weekend second in points, 28 points out of first. ISOC also awarded five bonus points for each heat-race win during the season. Kamm took full advantage by winning all six heats this past weekend, earning him an additional 30 points. He won the Pro Open finals on Friday night and Sunday, and finished second in the Saturday final.

“I had lot of ups and down this year. I separated my shoulder and thought I was done after that, but I won my first race back,” Kamm said after receiving the champion’s red number plate. “This weekend I felt great, no shoulder pain at all. This is a dream come true.”

Kamm won the Pro Lite title in 2011-2012 and ended that season by moving up to race – and win – the Pro Open finale. His best previous finish in Pro Open points was second place in 2013-2014, and now the Kenosha, Wis., racer is a champion at age 23.

In 17 finals this season, he reached the podium 10 times with five wins, two seconds and three thirds. In winning his first Pro Open title, Kamm dethroned Tucker Hibbert, the four-time defending champion who had won five of the previous six titles.

Five Polaris racers were in the top eight in Pro Open points. Petter Narsa (Hentges Racing) was fifth, Kyle Palin (Team LaVallee, Loctite, Polaris, Red Bull) was sixth, Ross Martin (Judnick Motorsports) was seventh and Corin Todd (Leighton Motorsports) was eighth.

In the final two rounds of Pro Lite racing, Jake Angove (Judnick Motorsports) won one final and won two of four heat races to take second place in the season points race. Nickolas Lorenz (Judnick Motorsports) took second in the final race of the season and Zak Mason (Team LaVallee, Loctite, Polaris, Red Bull) was third.

For the season, Angove had three wins and nine podium finishes, including seven in a row in the second half of the season. Joining him in the top 10 in points were Lorenz in third, Mason in fourth, Cole Cottew (Cottew Motorsports) in sixth and Evan Daudt (Daudt Racing) in seventh.

In the final two rounds of Pro-Am Women’s racing, Elina Ohman (Davies Racing) of Älvsbyn, Sweden, won two of four heat races and finished second in one final to easily secure the season points title. She won 14 of the season’s 16 finals, and 27 of 32 heat races.

Jakki Farmer (Fort Fremont Racing) finished fourth in points, Amanda Duitsman (Plaisted Racing) was fifth and Tausha Lange (Lange Racing) was sixth.

P-DRIVE WOBBLE

The all-new Roller Tower P-Drive primary clutch used on all the G-4 850’s from Ski-Doo has received another ingenious tweak designed to improve clutch alignment, reduce belt heat and soften vibration.

Listen up, because this is weird science. The fixed (back) sheave on the new P-Drive for MY 18 is actually cast so it wobbles. There’s .024 run-out on the sheave when installed on the crank.

To make this vibration absorbing effect work, the clutch and crank stub have to be timed together so the “wobble” occurs at a precise vibration cancelling moment during the engine’s 180 degree firing order.

The crank stub and the taper on the sheave are “D” shaped to ensure the clutch goes on correctly. The slight wobble also improves belt tensioning while compensating for vibration induced belt misalignment.

Yeah, we said it was weird science. Once again Ski-Doo is tweaking our sensibilities with ground breaking innovation.

Who would have dreamed a wobbling clutch could be a good thing?

BRP VIBRATION DAMPING CLUTCH TECHNOLOGY

Since the launch of the REV Gen 4 platform, BRP has been using a Patent Pending technology on the pDrive clutch to minimize engine vibration.

This unique new solution adds no weight but solves the vibration issue many large displacement two-cylinder snowmobile engines experience.

To minimize vibration from the extra 50cc’s, extra 10 horsepower and 30% faster response of the Rotax 850 E-TEC, Ski-Doo engineers designed an industry first, counterbalancing pDrive fixed clutch sheave.

Those with a keen technical eye will notice the D-Shaped crankshaft alignment and the twenty four thousandths (.024) of an inch (.6mm) precise offset or runout built into the clutch sheave.

This runout keeps the belt more perfectly tensioned within the primary and secondary clutches to reduce vibrations sent into the chassis through the secondary clutch.

The timing of the runout’s high spot meeting the belt is synchronized with the engine’s firing to offer a counterbalancing effect without added weight or complexity. The net result is less vibration transferred into the chassis and the rider.

Because of reduced vibration transferred to the belt, the belt temperature remains stable or even cooler, compared to not having this runout.
