LUMIKENTTIEN SURFFARI

LUMIKENTTIEN SURFFARI

Wille Rajala on uusi tuttavuus MK-lehden avustajakaartissa. Miehen ensimmäinen juttu viime kevään kakkosnumerossa käsitteli Brett Rasmussenia ja edellisessä MKlehdessä oli Rajalan raportti Hay Days –tapahtumasta. Mutta kuka oikein on Wille Rajala?

Ensimmäisen lumilautansa 45-vuotias Wille Rajala kertoo rakentaneensa vuonna 1982.

– Kun navetan katolta pääsin laskemaan lumen pinnalla muutaman sekunnin, tunne oli todella mukaansa tempaava, Rajala muistelee.

Oikealla lumilaudalla Rajala ryhtyi laskemaan vuonna 1984, joten hän kuuluu alan pioneereihin Suomessa. Laji vei nuorukaisen mukanaan kertalaakista pariksikymmeneksi vuodeksi. Vuonna 1985 hän osallistui SMkilpailuihin ja vuotta myöhemmin ensimmäisiin EM-kilpailuihinsa. Tuolloin lautailu oli pääasiassa samanlaista ratalaskua kuin kahdella suksella kilpailtavat alppilajit.

Rajala kiersi maailmancupin lautailukisoja Keski-Euroopan lisäksi myös Pohjois-Amerikassa ja Japanissa vuoteen 1999 asti, jolloin hänen poikansa syntyi. Vuosien mittaan hän alkoi laskea yhä enemmän rinteiden ulkopuolella.

– Haluan tuntea kurvien g-voimat jalkojeni alla uudelleen ja uudelleen. En ole koskaan ollut innostunut lumessa tarpomisesta, joten sekä moottorikelkka, lumikissa että helikopteri tulivat tutuiksi pääsemisessä lumisten vuorten huipuille Pohjoismaissa ja Amerikassa.

Iän myötä Rajala kertoo tulleensa aina vain valikoivammaksi kelin suhteen. Lumen pitää olla sopivaa, näkyvyyden hyvä, muiden jättämiä jälkiä ei mielellään saa olla näkyvissä, rinteen on oltava riittävän pitkä ja jyrkkä. Lopulta laskeminen alkoi muuttua haastavaksi, ainakin niin että Rajalan vaatimukset olisivat täyttyneet.

BRP Supporting Free Avalanche Awareness Seminars and New Online Education Program for Snowmobilers

BRP Supporting Free Avalanche Awareness Seminars and New Online Education Program for Snowmobilers

BRP is amplifying its efforts to provide avalanche education and awareness by sponsoring more than 40 free seminars throughout North America for the seventh straight year, and adding two strong partners to further the effort. New this year is support for the seminars from Backcountry Access (BCA), one of most well-known and respected manufacturers of avalanche safety equipment in addition to joint sponsoring of the new Backcountry Ascender online education platform. Combined, the two platforms will ensure an increased number of riders have access to essential tools for avalanche education.

More than 13,000 snowmobilers have taken part in Ski-Doo-sponsored avalanche awareness seminars since 2009. The in-person seminars offer engaging content for riders of all skill levels, and riders of all brands are welcome and encouraged to attend. Those who register to attend are also encouraged to bring their friends and riding buddies to ensure people they ride with are also well informed.

In addition to sponsoring seminars, BRP and BCA are also teaming up with Backcountry Ascender, a recently-unveiled online platform. It is free, and is a self-directed program that provides basic avalanche education and encourages traditional courses to advance to higher levels. Much of the course content can be completed online, and it will direct users to relevant in-person courses like the BRP/BCA-sponsored seminars. Backcountry Ascender is supported by the International Snowmobile Manufacturer’s Association (ISMA), of which BRP is an active member.

“Safety is a priority for BRP, which is why we are so deeply involved in the promotion of avalanche education,” said Mathieu Laforest, Global Ski-Doo Marketing director. “Together with our dealers, we’ve worked with experts to design snowmobile-specific seminars that are educational and engaging for participants. With the addition of Backcountry Ascender and BCA this year, we’re looking forward to raising the level of awareness and education even further.”

About the Seminars
Seminars in Canada are led by Marshall Dempster, a recognized avalanche forecaster, a Lead Instructor (AST1 and 2) and Backcountry Guide. Dempster is a Professional Member of the Canadian Avalanche Association, professional forecaster and certified Canadian Avalanche Rescue dog handler. He has 15 years of mountain experience focused on safe travel as well as mountain rescue and a passion to share his knowledge.

Mike Duffy of Avalanche1, a recognized snowmobile expert in avalanche awareness, leads seminars in the United States. Duffy has American Avalanche Association Levels I & II, AvPro Level III and Instructor certifications, teaches at Colorado Mountain College and Silverton Avalanche School, and has been giving snowmobile-specific avalanche classes since 1996. Duffy has more than 25 years of mountain riding and mountain rescue experience. This is his fifth year working with BRP.

Seminars are open to owners of all brands of sleds. For up-to-date information on locations and times, or to register for an avalanche awareness seminar, visit the Ski-Doo website, the
Ski-Doo Blog and be sure to follow Ski-Doo on Facebook. Most seminars are combined with an open house or mountain-riding event. Participants are encouraged to register with the host dealer so they can plan meeting space accordingly and ensure a spot.

Ride Rasmussen Style Lands in Europe!

The Idaho, USA based snowmobile riding school Ride Rasmussen Style will launch its European operations in January 2016 based in the Arctic Circle Finland. Bret Rasmussen, the founder of Ride Rasmussen Style and a legendary snowmobile racer and innovator is thrilled to start the new era for his beloved riding clinics.

Bret Rasmussen who has been involved in winter motor sport for decades, have always wanted to share his knowledge as well as his skills with other riders, allowing riders to advance in the backcountry as fast as the snowmobiles develop annually.

Ride Rasmussen Style is located in Preston, Idaho and headquarters its operations in West Yellowstone, Montana and has also featured clinics in Utah, Wyoming, Colorado and Montana. Annually, Bret Rasmussen has also been invited to school riders in various other countries and continents.

As a result of high sales in mountain sleds, there is a natural demand for educating the existing riders as well as new comers.  The Ride Rasmussen Style clinics instruct riders on how to set up their machines and provide instruction on riding techniques providing more enjoyment while in the backcountry.

The Ride Rasmussen Style Europe representative is Wille Rajala, a former multi time snowboard champion and one of the pioneers in starting the sport in 1984 which was based in Finland.

Wille Rajala is a Finnish Lapland based entrepreneur and experienced mountain rider from a town called Rovaniemi, which is the home of the only BRP snowmobile plant in Europe.

Wille Rajala has strong background in branding and business development. He is a husband and a father to one teenager son. After leaving the global snowboard circuit to be an entrepreneur, he kept mountain life close to his heart.  He feels now is the perfect opportunity to get back to nature and snow, the elements he loves the most.

The operations will start in the first quarter of 2016 operating in the mountains of Swedish Lapland. The first Ride Rasmussen Style Europe Camp will be held in April 2016.  More organized details will be announced in January.

The idea for launching the Ride Rasmussen Style Europe operations developed between both parties during 2015. Bret Rasmussen is a very experienced rider and highly appreciated person that visits global events. He feels that this opening is the first attempt to bring his strong team of schooled and skilled teachers in front of the snowmobile industry. It’s Bret’s hope the Ride Rasmussen Style clinics will advance providing more opportunities in other countries.

Wille Rajala is in charge of all European activities and camp inquiries, as well as for official merchandise.

Bret Rasmussen is looking forward to the new European activities and territories joining the Ride Rasmussen Style experiences. He is confident Wille Rajala is the right person to lead the new Ride Rasmussen Style chapter.

Rasmussen Suspension 101

Rasmussen Suspension 101

Rasmussen suspension setup explained.

I get many inquiries about how I set up my suspension on my personal sleds. In this explanation I will attempt to help my fellow sledders understand my philosophy on what I think is the ultimate back country suspension setup. My suspension setup is somewhat unique to the rest of the industry and it has come over many years of riding hill climb competition sleds and backcountry sleds as well. My suspension setup is primarily developed for off trail, backcountry and deep snow operation and is designed to promote less rider effort to maintain control of the sled when using proper technique and good form.

Ski shocks, Fox Factory IFP R with RCS regressive spring packageFirst off I must defend the OEM’s in that they develop suspension calibration for the average rider snowmobiling in average conditions. The ski suspension is soft and intentionally easy to roll up on edge for hill side operation. Bare in mind that the calibration is setup to perform with the mindset that the rider will be operating the sled with both skis on the snow and sharing the load of the sled. The rear suspension is also somewhat soft and calibrated to soak up the bumps for average riders which it does very well. Combined with the T-motion and flex edge track offered on the Ski Doo Summit Gen 4 rev, this sled is very easy to roll up and ride on edge for traversing hill sides even with improper rider form.

As I describe my preferred suspension setup the reader must understand that this setup may not be desirable for all riders and that my setup is specifically configured to conform to the technique which I teach and is geared toward more aggressive riders. When setup correctly this suspension will give the rider a more positive feel for how the ski and track are engaged in the snow. It will improve hillside operation helping to prevent washout (when the sled wants to turn up hill) while traversing a hillside. It will better prevent over transfer, but allow the track to stay engaged in the snow providing better traction. And I will help to prevent A-arm damage due to not enough suspension capacity while riding on edge or on one ski.

With the ski suspension I prefer a firm but not too stiff ride. I like the chassis to remain flat while cornering and while on edge I like that one ski will carry the whole weight of the sled without being too far into the stroke of the shock. I accomplish this using a regressive rate coil over spring package. While the KYB shocks on the Summit X model are very adequate for my setup, I prefer the Fox Factory IFP R. The regressive spring package offers a very firm initial spring rate to prevent chassis from rolling in turns and as the suspension compresses the spring rate actually reduces preventing an over stiff suspension that won’t collapse. Then at the end of the stroke the spring rate rapidly increases preventing bottom out.

All of this is accomplished using two springs, the first spring is locked out at initial compression preload causing only the second spring to be active. Part way into the stroke both springs become active reducing spring rate. This allows the suspension to continue to collapse without getting over stiff. In other words the suspension stays free. This article is not intended to explain spring theory, however this deserves an explanation since I want you to fully understand how this happens. When you add coils to a spring it will always reduce spring rate making the spring easier to compress. This should not become confused with preload as preload does not change spring rate; it simply changes the load that the spring can carry at the beginning of the stroke. Then as the suspension nears full stroke the first spring again becomes locked out greatly increasing the spring rate and preventing bottom out. Go to my web site for an animated graphic of how this all works:  http://riderasmussenstyle.com/brets-tech-tips/Skinz ARC

I want my sled to perform at its peak in the most adverse and extreme technical situations, therefor the ski shocks are calibrated to carry the load of the sled on just one ski. When I traverse a hill side on edge, the suspension will be able to carry the weight of the sled and still have working travel left. This will allow the suspension to collapse over an obstacle such as a log or stump that is hidden in the snow without taking out the whole suspension.

As for the rear suspension, I like the center arm to fall out helping the sled to maintain an edge. Most suspension tuners will tell you that the limiter strap on the center arm is used to control transfer or ski lift. I like to lengthen my limiter strap maximizing the distance that the center arm can fall out. This makes holding a hill side for extended periods much easier. For the spring I will install a progressive rate spring that starts at 140 PSI per inch of travel and finishes at 400 PSI per inch of travel. I also install a very soft helper spring that allows the suspension to collapse very easily for the first bit of travel allowing the track to climb out on top of the snow rather than trenching. I install this whole package with just enough preload to hold the spring retainer in place. I end up with a center shock that is initially very soft and plush, but very hard to bottom out when casing a mogul.

The rear arm is where I am able to control sled transfer or ski lift. I like my sled to lift the skis a few inches off the snow and hold, giving me maximum control and allows me to pick a line through technical terrain. Most sleds over transfer and are very difficult to control and remember the first thing most riders will do is to pull the limiter strap up. While this will control transfer, it will make the sled harder to control because it will be more difficult to hold on edge. Additionally shortening the limiter strap will prevent the track from being fully engaged in the snow and will reduce traction. By using a much stiffer rear arm spring and a slider block that changes the leverage point on the spring making it seem progressive, I can control the transfer. This system allows an initial soft ride and prevents over transfer. When calibrated right, the rear of the sled will squat to the point where the slider block changes leverage points on the spring and then hold. At this point the sled weight is all transferred to the rear arm spring and the spring is heavy enough to handle the load and should not bottom out.

This suspension calibration is such that the springs do much of the work reducing heat buildup in the shocks. Because we are relying less on the shock hydraulics to do the work the springs should be doing the suspension becomes much freer moving. The skis and track are engaged more positively in the terrain and the rider has more control.

The Revolutionary Titanium Spring Package

tech-tips-sprint-kit

 

Over the last 5 years, Renton Coil Spring and Bret Rasmussen have developed a revolutionary titanium spring package designed to increase handling characteristics, and performance.

Ski springs…

For backcountry riding, adding the RCS Regressive Ski Spring Kit is the biggest improvement you can make to your sled.  This patent pending system starts out with the constant spring rate of the main spring.  When compressed to a certain point, the helper spring is engaged and the spring rate drops.  This continues until the helper spring reaches full travel and the rate returns to that of the main spring.  This “regressive” rate curve helps from overloading one ski when side-hilling or when you’re on uneven terrain.

Front arm spring…

The front arm is the point of initiation of the skid travel.  RCS has developed a progressive spring package which starts out soft and gradually increases in spring rate.  This softer initial rate enables the skid to begin traveling earlier than stock setups and gradually gets stiffer to protect the suspension from bottoming out.

Torsion springs & block kit…

To complement the progressive front arm spring, we’ve spec’d stiffer torsion springs along with our patented rising rate torsion blocks.  This setup again starts out softer and progresses into a stiffer spring rate to prevent the suspension from bottoming out.

RCS has been supplying top manufacturers, racers, and backcountry enthusiasts with high performance springs for over 15 years. Whether you’re a racer looking for an advantage or a consumer looking for the best performance from your sled, RCS Titanium Springs are worth every penny.
