Fall can be a gloomy time for motorcyclists. Not only does autumn usher in the end of the riding season in many parts of the country; it also spells the end of a number of motorcycle racing series. There is a bright side to this time of year my friends…EnduroCross! If the series opener on August 27 in Duluth, Georgia is any indication, the racing is going to be epic.

Taddy Blazusiak scores the holeshot in front of the K&N banner

As a major sponsor of the series, the iconic red and orange K&N banners draped around Infinite Energy Arena served as a vibrant backdrop to the racing action. After a one year hiatus from the series, Taddy Blazusiak made his return to the EnduroCross starting grid in style. Out of the gate, Blazusiak captured the $500 Nexen Tire Holeshot Award on his Red Bull KTM. If there were any doubts that Blazusiak would again be a contender in the series, that holeshot put those thoughts to rest.

Lead changes are frequent in the sport of EnduroCross and Blazusiak relinquished the lead to a very fast Colton Haaker on the second lap. Then, with a mistake in the treacherous rock section, Blazusiak gave up two more spots, dropping to fourth. However, he showed why he is a five-time EnduroCross series champion with a late charge and pass to finish on the podium.

The top two spots on the rostrum were claimed by the two elite performers from 2015. Not satisfied to rest on last season’s accomplishments, defending series champion Cody Webb finished in the second position. The man who battled Webb throughout the 2015 championship series, Colton Haaker, won the season opener in a fast and consistent main event ride. The friendly but fierce rivalry between these two has been reignited for 2016.

Blazusiak’s return to the EnduroCross grid is big news for the series

Webb, Blazusiak, and Haaker will likely battle elbow-to-elbow and wheel-to-wheel in every round of the EnduroCross series, which will resume on September 3, in Brandon, South Dakota’s Badlands Motor Speedway. The trio brings very different styles and backgrounds to the series which only adds to the drama and excitement. However, the talent pool in EnduroCross is much deeper than just the top three riders. There are a dozen contenders in the field that can win on any given weekend.

For those unfamiliar with the sport, EnduroCross is an exciting mix of enduro, motocross, and trials racing. The course is a challenging combination of boulders, logs, water, and dirt. Staged in arenas, the racing atmosphere is intimate, fan-friendly, and worthy of a look for any motorcycle race enthusiast.

Remember, whether your motorcycle has knobbies, road tires, or racing slicks, K&N likely has a filter for it. Check out K&N’s online catalog search feature for your high-performance motorcycle filtration needs.

Elias has reason to smile with a legitimate chance at a Superbike title

There may be no other company with a name more inseparably linked to championship motorcycle racing than Yoshimura. Since 1954, when Hideo "Pops" Yoshimura started the company in Japan, the family business has been tuning and squeezing every bit of power out of motorcycle engines. Yoshimura produces arguably the most legendary and recognizable high-performance exhaust systems in the world.

Since the inception of the AMA Superbike class in 1979, Yoshimura has been a major player on the circuit. In fact, Yoshimura is the most decorated team in the history of the series with 13 championships. It is no surprise that Yoshimura Suzuki riders and bikes are again poised near the top of the standings in the 2016 MotoAmerica AMA Superbike season.

With one stop left in the 2016 championship season, the Yoshi team has two riders in serious championship contention. Toni Elias is sitting in third position in America’s premier road racing class. Elias is only a scant 6 points out of second place and 25 points out of first. Elias is a seasoned racer having won a championship at the MotoGP Moto 2 level. Just behind Elias is teammate Roger Hayden who is also within striking distance of a season top three finish. Hayden is in his third year with the Yoshi team. Throughout the 2016 season, Elias and Hayden have been ultra competitive with repeated podium finishes. The combination of immensely talented riders and the rock-solid backing of the progressive Yoshimura racing empire is a clear recipe for Superbike success.

Not surprisingly, K&N Engineering is a long-time sponsor of the Yoshimura Superbike team. For a company like Yoshimura, that is known for high performance exhaust systems, to be partnered with the undisputed leader in intake filtration technology is a no-brainer. The race-hot exhaust exiting those Yoshimura Suzuki GSX-R1000 headers, pipes, and mufflers enters as clean, cool air through K&N filters. A free-flowing exhaust requires a free-flowing intake. Yes, K&N and Yoshimura is a match made in racing heaven.

K&N performance is not just available to Toni Elias and Roger Hayden. We mere mortals can bolt on high-performance K&N filter technology to our bikes as well. Any late-model Suzuki GSX-R1000 can benefit from the proven filtration and increased air-flow of a SU-1009 air filter. A closed-course GSX-R can breathe through the race-specific SU-1009R. To keep that hot oil clean, try the screw-on KN-138 oil filter or the chrome-plated KN-138C. Remember that K&N oil filters not only feature excellent internal filtration technology, but also the convenient 17mm end nut for easy installation and removal. Take a look at K&N’s easy-to-navigate online catalog to find parts for your particular motorcycle application.

As far as Yoshimura Suzuki’s bid for the MotoAmerica AMA Superbike crown, the final round at New Jersey Motorsports Park on September 9-11 will tell the tale. Roger Hayden and Toni Elias will push their GSX-Rs to the limit on the 2.25-mile track which features 12 corners and a half-mile straightaway. The racers should be familiar with the layout since this is the second visit to NJMP on the Superbike schedule. In addition to the Superbike races, the weekend will feature Superstock and Supersport racing.

For you gear-heads and race fans, here are the specs on the Yoshimura Suzuki race bikes:

Bike - 2016 Suzuki GSX-R1000
Engine - Yoshimura-tuned 998.6cc, 4-stroke, 4 cylinder, liquid-cooled, DOHC, 16-valve
Transmission - 6-Speed
Exhaust - Yoshimura Special Tapered Alpha Titanium 4-1 Full System

The UNKNOWN team leaving their mark on the pavement

UNKNOWN Industries? With millions of YouTube views and hundreds of closed-course stunt demonstrations, one has to question the accuracy of the company’s moniker. While the name is certainly an understatement, there is nothing understated about a performance by the Harley-Davidson® freestyle stunt team. UNKNOWN has become world-renowned for its riders’ highly technical and highly entertaining ripping and thrashing of their behemoth Harleys.

Co-owner and Team Manager John Oakes is quick to sing the praises of the riders that fuel the UNKNOWN brand. Oakes calls them, “A new breed of Harley riders who push the limits of their motorcycles and themselves.” Certainly, a motorcycle performance and stunt company is only as good as its riders and UNKNOWN has some of the best. Before they had ever met, co-founders Nick Leonetti and Buddy Suttle knew of each other through their respective racing and dirt riding reputations. When they finally came face-to-face, creative sparks flew (literally) and the rest is history. The duo’s reputation has grown in like proportion to the creativity of their stunts. Suttle has been featured on the cover of Baggers Magazine and Leonetti has graced the cover of Hot Bike Magazine. It’s hard to stay “unknown” with that kind of high-profile recognition.

Rounding out the talented lineup are three stunting phenomes who all cut their teeth in motocross and/or BMX. Kade Gates, who became a fan of UNKNOWN watching YouTube videos, now rides his Harley FXR alongside the founders. Jeff Palkiewicz traces burned rubber designs on the asphalt on his Dyna FXDXT aptly named “Kentucky Disco Biscuit.” Then there is Logan Lackey who is the talented son of famed motocross champion, Brad Lackey. Logan says, “I knew I wanted to be part of the UNKNOWN family from the first time we rode together.” All of the young guns of the UNKNOWN team share an all-consuming passion for taking their Harleys to the teetering edge of what is possible on bikes weighing in at nearly double that of modern sportbikes.

The company’s notoriety started with amazing live performances and those shows are still UNKNOWN’s foundation. The riders amaze fans at events ranging from NASCAR, the Sturgis Motorcycle Rally, Supercross, UFC, H-D® dealerships, X-Games, military bases, massive music festivals, the Hot Bike Tour, and various other events across the US. Anywhere adrenaline junkies gather there’s a good chance UNKNOWN Industries will be there as well. Audiences witness wheelies, burnouts, and metal-grinding stunts that are combined into an over-the-top, visceral rumble-fest.

That live performance success has been parlayed by the team into Internet and media superstardom. The first 13 episodes of their Harley Wheelies YouTube series have garnered over 5 million views. The newly released YouTube miniseries titled The UNKNOWN Ride will certainly follow suit. The media frenzy doesn’t stop there. UNKNOWN riders have been featured in TV shows, music videos, TV commercials, and magazines. If that’s not enough, you can find UNKNOWN's second feature length movie, Into the UNKNOWN, on both DVD and iTunes.

Keeping UNKNOWN’s stable of Harleys protected and running strong is where K&N comes in. K&N’s sponsorship of the company goes beyond financial support. Oakes says, “All of the team riders run K&N air filters.” Interestingly, 3 of the 5 riders pilot early 90s FXRs. Those of you out there with the same bike have a multitude of K&N intake and filtration options. The filter that fits the stock 1992 FXR, as well as most other 90s Harleys, is the HD-1390. For a custom intake assembly, you can opt for something like the round RK-3911 or the teardrop RK-3912, both of which feature chrome covers. Of course all K&N intake options are designed for increased horsepower and highly effective filtration. There are high-quality K&N oil filter options for the bikes as well, such as the chrome KN-170C and the very cool, billet aluminum SS-171. If you ride just about any Harley, K&N has great filtration options for you.

In the end, I guess the only real “unknown” is what UNKNOWN Industries will dive into next in their quest for total world domination in the moto-entertainment industry. One thing is certain, take a look at one of their videos or attend a performance and you will never look at a Harley the same way again.

Thanks to the innovative design of the 63-1131P air intake, K&N guarantees that this kit will increase the power to the wheels of your H-D motorcycle.

Big "hogs" have been owning the road since the first V-Twin engine was introduced in 1909. These legendary motors have seen many incarnations: Flathead, Knucklehead, Panhead, Shovelhead, Evolution, and Twin Cam 88. The latest generations 2008-2011 Harley-Davidson Twin Cam 96 V-Twin and the 2009-2015 Harley-Davidson Twin Cam 103 V-Twin contain numerous innovations that are designed to provide the low end torque that Harley's are known for. Lightweight pistons allow the engine to create power faster, while balance shafts help to offset vibrations on ridged mount applications like the Harley Softail. But it doesn't matter which H-D® model you ride, you can boost the horsepower and torque by simply adding a K&N 63-1131P AirCharger performance intake system.

The 63-1131P air intake kit includes everything you need to give your Harley extra power today. All you need to provide are basic hand tools and you can be down the road in an hour and a half or less.

Each Harley-Davidson spins that drive belt by filling its twin-cylinders with a combination of gasoline and air. Once this power mix is ignited by the spark plugs, the resulting explosion pushes the piston downward, turning the crankshaft, and ultimately the back wheel. But the gasoline has to have oxygen in order to burn in that explosion. To facilitate this, air is pumped to the cylinders through the intake system, which is located behind that chrome air cleaner cover on the side of your V-Twin engine. However, the iconic styling actually limits the volume of air that's able to enter the system, and that restricts the amount of horsepower and torque that your Harley Twin-Cam engine makes. The K&N 63-1131P AirCharger performance intake system takes care of this problem by opening up a direct airflow path to the cylinders. Plus, the heat resistant chrome finish blends with the look of any Harley Twin Cam 96 or Twin Cam 103.

But of course, talk is meaningless without the proof to back it up. So to verify the performance of every K&N cold air intake, we conduct before & after dyno tests of the vehicles each system was designed for. Since the K&N 63-1131P AirCharger performance intake system will work on both the Harley-Davidson Twin Cam 96 V-Twin and Harley-Davidson Twin Cam 103 V-Twin, we tested a 2015 Harley-Davidson Electra Glide 103 ci, and found that it made 68.20-hp and 87.77 lb-ft at the rear wheel with the Harley-Davidson factory air intake and 75.00-hp/94.81 lb-ft after a K&N AirCharger intake was installed. That's an estimated increase of 6.80-hp and 7.04 lb-ft, which you'll certainly notice with a little throttle input.
