2-STROKES vs. 4-STROKES

0

From the many questions and quotes we see online it’s clear some people may not understand the difference is between a 2-stroke and a 4-stroke engine.

It’s not a matter of life or death to know or not, but it does help to be able to distinguish between the two engine types and know a little more about what’s idling under your seat. So here is the simple explanation of the differences.

2-stroke engines have a power cycle every time the piston moves up and down inside the cylinder. The first stroke includes intake and compression of fuel and air which forces the fuel and air mixture up the transfer tube to the intake port and into the combustion chamber. The second stroke includes the combustion of that fuel and air and its exhaust.

The 4-stroke engine essentially follows this same process except it is taking two rotations of the crank to complete all four cycles instead of just one. The four cycles include: Intake of the fuel and air mixture on the down stroke, which opens the intake valve to let the air and fuel mixture into the combustion chamber, compression of the air and fuel mixture as the piston moves up inside the cylinder, then combustion of the mixture which forces the piston down inside the cylinder and then finally the exhaust valves are opening and the fumes are forced out of the combustion chamber on the up-stroke.

Many ATV enthusiasts remember the distinct sound of the late eighties Honda 250r ATV as it was quite possibly the hottest race ride from the nineties and on into the mid 2000 cross-country and ATV motocross scene.

The ding, ding, ding of the motor and the smell of mixed race gas coupled with awesomely explosive power was something that attracted many to the sport. Eventually though the ringing of the two banger would be replaced by the BRAAAP of the four stroke motor.

There are benefits to each of these mills and it is a hot topic in the powersports industry. At least now instead of replaying last night’s episode of Duck Dynasty in your head you’ll be able to stay involved in the conversation next time your resident gear head starts spouting off.

Launch of Kolpin Cabs at 2013 Indy Dealer Show

0

Kolpin Powersports is launching a new cab enclosure system that combines incredible visibility and maximum protection from the elements with head-turning style.

The scratch-resistant qualities inherent in tempered glass and other advanced materials used in the construction will afford UTV dealers and customers alike a premium sales value.

Kolpin will be selling the all-new cabs on a new website, www.kolpincabs.com and also through partnering Distributor in the United States, Western Power Sports, to dealers in the Power Sports channel.

The doors and windshield are comprised of crystal-clear automotive glass and double-hard-coated advanced Polycarbonate with a steel understructure maximizing the view for operating implements and navigating rough terrain—visibility other cabs can’t offer.

Kolpin Cabs make everything from crossing a frozen lake to running down trails more comfortable! Part of the revolutionary advantage of the Kolpin system is their incredibly easy installation.

Panels and doors are computer designed for each UTV model with a laser-accurate, draft-proof fit. Kolpin Cabs are easy to assemble and components can later be removed or re-installed in minutes, not hours—guaranteed! Riders can receive a kit, install it and get to work or play the same day!

In addition to their durable, transparent design and easy installation, Kolpin Cabs have other incredible features combined in a clean package that is guaranteed to thrill equally in the woods or on the showroom floor.

The windshields are comprised of incredibly tough automotive safety glass. Holes are pre-drilled and plugged for addition of an optional windshield wiper and washer kit.

The shield tilts outward on heavy-duty gas shocks and can also be propped open with built-in support brackets. The zinc-plated and powder-coated metal roof installs quickly and includes sound-absorbing insulation. The rear panel is comprised of tempered glass.

The combination safety glass/ double-hard-coated polycarbonate doors install into the stock mounts on the vehicle chassis and pivot 180 degrees for ultimate accessibility. A best-in-class two-stage door latch keeps occupants secure and the keyed locking feature will help UTV owners rest easier when they’re not riding.

An optional cab heater/defroster with a three-speed fan is also available. The Kolpin system is infused with the latest materials and geometries to ensure lighter weight and maintain vehicle stability while retaining the strength needed for years of service and a high trade-in value.

All-new Kolpin Cabs can be installed to upgrade Polaris Ranger models from years 2009 through 2013, including the 2013 Ranger 900 XP. Kolpin offers the ultra-clean kits for all Can-Am Commanders manufactured to date. Cabs are also available for Yamaha Rhinos, Honda Big Reds, and the Kawasaki Mule 4010 and 6010.

Full service and support will be available via Kolpin dealers nationwide the moment the cabs land on showrooms. Seeing is believing.

Yamaha Motor Corp., U.S.A., announces the fifth anniversary of its OHV Access Initiative, the industry leader in Guaranteeing Responsible Access to our Nation’s Trails (GRANTs).

Launched in January, 2008, the program has aggressively funded the ever growing and diverse needs of the OHV community in support of its mission of promoting safe, responsible riding and open, sustainable access to riding areas. A few of the highlights of the past five years include:

– 200 GRANTs and more than $2 million in funding and equipment in pursuit of the program’s mission.
– GRANT-funded projects in 37 of our 50 states. The GRANT tracker map showcases the program’s cross-country appeal and highlights future opportunities for underrepresented areas.
– Yamaha employees have personally embraced the tenets of OHV Access Initiative, putting in more than 1,500 volunteer man-hours planting trees, clearing trails and supporting restoration efforts on company-adopted trails in the San Bernardino National Forest.
– A new address, www.yamahaohvaccess.com is where you can download our application and submission guidelines and find our calendar of deadlines.

“Yamaha is very proud of everything the OHV Access Initiative has accomplished throughout these five years, but the challenges before us remain,” said Steve Nessl, Yamaha ATV and SxS marketing manager. “Yamaha will continue to focus on the OHV program’s mission and reach out to riding groups and other appropriate organizations to strengthen opportunities for motorized recreation today and in the future.”

As part of its on-going program, the OHV Access Initiative closed out the 2012 funding cycle awarding more than $76,000 in GRANTs in the fourth quarter bringing the year’s total to $375,000. The following organizations received GRANTs in Q4 2012:

YOU GET WHAT YOU PAY FOR

0

Not all aftermarket accessory parts are created equal. If you search the Internet for a part or accessory for your ATV or SXS and you only search for the lowest price, you might be cheating yourself in more ways than one.

Major manufacturers tend to build quality products for their off road vehicles and if you want a part that will last, work well and fit your vehicle correctly, it pays to search within their accessory catalogs first.

Companies such as Can-Am have many high quality parts that have been tested and proven to last. When I buy a product, whether it’s a roof, set of bumpers or even something as simple as a winch mount I look to see what the manufacturer of the vehicle offers first because I know it will fit right and install with usually very little effort.

A friend recently purchased a universal top for his side-by-side and bragged about the smoking deal he got. After riding through a few trails he noticed the top tearing away from its mounts because the plastic was paper-thin and the mounts were so small that it couldn’t handle the strain of a few small branches. After tearing it off to dispose of it he realized he was out $125 and still needed a top for his ride.

When considering what you’re paying for, the price should include a return policy, warranty information and shipping costs because if you aren’t satisfied with the part and get stuck with it because you bought bargain bin, bottom shelf products then how much did that piece really cost you?

CAN-AM’S JOSH FREDERICK EARNS PODIUMS AT WORCS

0

Team Motoworks / Can-Am Pro Josh Frederick piloted his Can-Am Maverick 1000R X rs side-by-side vehicle to a third-place podium finish and his DS 450 ATV to second overall at the second round of the World Off-Road Championship Series (WORCS) this past weekend in Primm, Nevada. Fellow SxS Pro Production side-by-side class and Can-Am Maverick racer Pablo Veglia finished fifth.

“We were very pleased with how round two turned out, having Josh Frederick reach both Pro class podiums with the Maverick and DS 450. I was definitely happy with how Josh raced and finished with the Maverick 1000R X rs in just his second WORCS event. Coming from the fifth row at the start, and as far back as 20th, to earn a top-three finish shows just how skilled both he and the Maverick are,” said Jimmie O’Dell, Race Manager, Can-Am. “To have two of the five Maverick side-by-side vehicles entered, finish in the top five of the highly competitive Pro Production 1000 class is great and definitely the momentum that we were looking for which we can build upon.”

For Frederick and the Maverick 1000R, round two, held at Buffalo Bill’s, just outside of Las Vegas, served as redemption for an unlucky series opener a few weeks prior when he failed to finish.

In Primm, Frederick was determined to move forward from his fifth-row starting spot during the six-lap Pro race. After lap one, Frederick was in 15th, but on the move. One lap later he had picked off five racers and cracked the top 10. By the fourth lap, the Nevada resident had pushed his Maverick 1000R X rs to fourth overall.

He cracked into the top three on lap five and held it all the way to the finish for the first-ever WORCS podium finish for the new Can-Am Maverick. Frederick had a similar climb in the Pro ATV class, as he came from eighth place to eventually put his Motoworks-tuned DS 450 on the podium.

“There are some things we need to work on, but to be able to run up front with a brand new vehicle is great. We’ll just keep working on the Maverick and get better and better,” said Frederick. “The DS 450 was working awesome. I have to give it up to my whole team. I am happy with second place.”

Of the four remaining Can-Am Maverick 1000R side-by-sides in the SxS Pro Production, three finished in the top 15. Veglia (Team Del Amo Motorsports / Can-Am) earned fifth, battling back from 17th place after lap one. James Hill and Johnny Leach finished 12th and 13th, respectively with their Can-Am race vehicles.

Two other Can-Am-mounted racers competed in the ATV Pro class along with Frederick, who currently sits third in the class points standings.

Finishing seventh aboard his GPS / Can-Am DS 450 was Pro class rookie Collins Webster. His teammate, Dillon Zimmerman, had two mechanical issues and will look to rebound at round three, March 22-24, in Lake Havasu City, Ariz.

STI ADDS NEW FINISHES FOR HD2se & HD BEADLOCK

0

STI Tire & Wheel has gone to the dark side with the addition of dramatic black finishes on two HD Alloy wheel models.

This expansion gives ATV and UTV owners even more customization choices, at the same unbeatable bang for the buck the entire HD Alloy line is known for.

STI’s popular HD2se wheel now sports a dazzling Gloss Black finish, joining its Matte Black/Machined and Gloss Black/Machined siblings in the HD2 inventory.

This new Gloss Black HD2se is available in 12×7, 14×7 and 15×7 sizes. Like all HD2 wheels, it is protected by a lifetime structural warranty.

This is due in large part to the HD Alloy’s unique inner and outer heavy-duty wheel lip reinforcement and as with every STI HD Alloy wheel, this model comes with a new, matching, low profile center cap.

Also slipping into stealth fighter mode is the HD Beadlock line, thanks to the addition of a Matte Black option to go along with existing gunmetal gray Slik-Kote and Bright Machined finishes.

This wheel features a unique integral-mount beadlock ring, which is quick to install, adds considerable strength to the outer lip, and is engineered to reduce debris buildup. Most importantly, the ring helps ensure the tire bead stays on the wheel, even when using lower pressures and applying high side loading.

HD Beadlocks also utilize an even thicker, stronger reinforced “rock crusher” inner bead lip, making these the most rugged wheels available.

The STI HD Beadlock is offered in 12×7 and 14×7 sizes, value-priced for budget-minded enthusiasts who want to step up to the performance benefits of a beadlock wheel.

These sultry new STI HD Alloy wheels are available at finer ATV/UTV dealers everywhere. For more information, visit stitireandwheel.com.

Live To Ride Another Day

0

There are a couple of things everyone should think of when riding with friends.

What some riders might not know is that your ATV doesn’t care who you are or who you think you are or even what you think you can do. It was made to do a task and if pushed too far will eventually expose your weaknesses.

Just a few nights ago I watched a reality TV show that featured a guy riding his TRX 250 into oncoming traffic as the producers raced alongside noting the top speed of his trusty ATV. Luckily for him he didn’t get hurt, but his luck will eventually run out.

Keep in mind that your friends want to have a good ride as well and contrary to the fact that they’ll do it, they do not want to have to haul you to the hospital.

The second thing to remember is that they probably wish you’d ride responsibly rather than try to showcase just how awesome you think you are.

Know this: show-offs eventually find themselves alone because no one wants to assume the risk of being around them.

Guthrie Wins 4th King of the Hammers with RZR XP

0

Since its original debut in 2008, the King of the Hammers (KOH) race has been deemed the toughest off-road race in the world.

This year’s course of 115-miles of open desert racing and huge rock trails proved to be the most-difficult course yet. So hard, that Race Organizer, Dave Cole didn’t think a UTV could do it.

When the dust settled only three of the 35 UTVs entered would prove Cole wrong, all beingRZR XP 900s! Mitch Guthrie and his co-driver Mitch Guthrie Jr., who has won four KOH races and took second once, would take the checkered flag with his Holz Racing RZR XP 900, with Jon Crowley and Blake Van de Loo, in their Jagged X-supported RZR XP 900 taking second, and Matt Enochs in the Team Nasty RZR would finish third.

Thirty-five UTVs lined up at 9 a.m. on Thursday morning to try to conquer one of the toughest KOH courses to date in eight hours or less.

Brandon Sims in his RZR XP 900 would get the early lead but succumb to the toughness of the course, along with 31 other racers throughout the race, leaving Racers Guthrie, Crowley and Enochs to duke it out for the win.

Guthrie finished the race in 7 hours, 51 minutes and 52 seconds, running the last four rock trails and 30 miles of desert with no brakes! Crowley finished only 16 seconds behind him! Enochs would finish with only five minutes left showing the grit and durability of the RZR XP 900 with a clean sweep of this year’s King of the Hammers!

Baron Takes Second Win in a Row at WORCS

0

After the swamp-like conditions at Canyon MX Park, in Peoria, Ariz., last month, the dry weather of Primm, Nevada for WORCS Round 2, Buffalo Bills, was a welcomed change! RZRs would, once again, take the top spot in all the side-by-side classes offered.

Polaris Racing/Holz Racing’s Beau Baron would, once again, steer his new RZR XP 900 to the win in the Pro Production class and first overall. Second would go to Ryan Piplic also in a RZR XP 900. Baron and Piplic sit one, two in the series standings after two races.

The Production 1000 class saw 16 RZRs line up and Mitch Guthrie Jr. in his Holz Racing RZR XP 900 again took the checkered flag. He also placed third overall behind Baron and Piplic. Jacob Shaw and Holz Racing’s Jake Greco in their RZRs finished second and third.

The Production 700 Class saw a majority of RZR 570s entered. Polaris Racer Cody Rahders would take second place to Holz Racing’s David Haagsma in another RZR 570 with round-one winner Michael Bunyea’s Holz Racing RZR 570 finishing third.

The Production 850 class also had RZRs take the top three spots with Alfredo Ramirez, Justin Lambert and Chris Willing finishing first, second, third. The Production 600 class, once again, only had one entry, Amelia Morton, who finished the race first.

The next WORCS race is Crazy Horse, in Lake Havasu City, Arizona, March 22-24.

BEST IN CLASS: BEST SPORT UTILITY SXS

0

WINNER: Polaris Ranger 900

Clearly, Polaris is rabid in its continuing conquest of the SxS business in every segment. The new Ranger 900 XP is the personification of the drive Polaris has towards growing its worldwide leadership in this industry.

The new Ranger 900 is precisely that: New from its tip to its tailgate. The vehicle is barely three inches longer but the wheels have been pushed further toward each end, making the Ranger more capable in rough terrain and enhancing ride quality.

The front and rear suspensions are so plush, you could mistake the ride for that of an RZR. The 900 motor is a 60-horsepower, single throttle body version of the RZR XP’s 88-hp mill. At 60 ponies this engine is immensely torquey and buttery smooth.

The fully tied-together driveline makes the old CVT-sub-tranny combo seem rough. There’s no driveline thrumming and a noticeably tighter feel on engagement and take-off. The cab features myriad improvements including an adjustable driver’s seat and huge underseat storage bins and the powertrain is now fully serviceable with the box raised.

One ride and you’ll be convinced this BIC Award winner is not just improved – it’s completely redefined the category.

Polaris practically invented the SxS genre and is proving it intends to continue leading it.

RUNNERS-UP: Can-Am Commander 800 XT & John Deere RSX 850i

Can-Am has nailed the dual purpose equation in the Sport/Utility segment with the Commander chassis. The dual level cargo box is a solid and functional hit with buyers. However, the commander’s sporty, performance feel and aggressive ergonomics play strong to the sport buyer.

We love the 800 Commander’s exhaust sound and more importantly, the delivery of power from a torquey, smooth V-twin. Again, we strongly recommend buyers upgrade to the XT package or, in MY 2013, the DPS package – the value here is too good to ignore.

Like a sleeping giant waking from a long nap, John Deere has re-emerged in the business it launched in the early 1990’s. We might have been impressed if it had come to the market with touched-up Gator, but the Big Green Machine didn’t do that – not a chance.

The new-from-the-ground-up RSX platform is a real Sport-Utility SxS that can play hard with anything in the segment. However, because it’s JD green, it’ll capably work hard and last for years.

There’s impressive stuff going on at Deere and the RSX is a clear indication of the company’s calculated commitment to the SxS market.
