Sunoco rookie of the year contender Dillon Bassett got his first career NASCAR K&N Pro Series East victory in the UPMC Health Plan 150, but it wasn't without some drama. Bassett made his 10th career NASCAR K&N Pro Series start and his previous best finish was a sixth in the season opener at Florida's New Smyrna Speedway. The 17-year-old from Winston-Salem, North Carolina became the 100th different winner in series history. To put the number 44 Bassett Gutters Ford in Victory Lane, Dillon had to sit through two lengthy late-race red flags, and then fend off a fierce challenge from Austin Hill in the closing laps.

Dillon Bassett took the lead in the UPMC Health Plan 150 from NASCAR K&N Pro Series East championship points leader William Byron, who led a race-high 92 laps, on Lap 94. Asphalt issues on the front stretch necessitated a pair of red flags and subsequent caution periods starting on Lap 101. When the race finally went back to green on Lap 120, Austin Hill charged from third to first and it looked like Bassett's first win would have to wait. However, Dillon was able to maintain his momentum on the outside and wrestle the lead back on Lap 125 before he drove away to a 3.357-second victory.

Race winner Dillon Basset said, "Those last 20 laps were absolutely crazy. On the restart we spun the tires a bit. It left enough room for the 22 (Austin Hill) to get up under us. We just kept digging, never gave up, and got the lead back on the outside."

Fellow Sunoco Rookie of the Year candidate Rico Abreu mounted a late charge to finish second, while Hill settled for third. Afterward Abreu commented, "Saved our tires as much as we could the whole race. Got going there at the end. Just wish we didn’t run so many caution laps at the end when they were trying to fix that hole because it really hurt us."

Scott Heckert, fresh off his win at Watkins Glen, drove the number 34 Project Lifesaver Chevrolet across the line in fourth, followed by J.J. Haley in fifth. William Byron finished 8 and as a result his championship lead shrunk to 12 points over Scott Heckert. Austin Hill sits 28 points back in third.

A disappointed Austin Hill said, "When we went back to green the 44 (Dillon Bassett) slid up the track. I knew that was my chance but he was able to get off the corners better than I was and was able to clear back by me. At the end of the race we started to get a four-wheel slide so I had to really stop the car to keep the car up under me."

The SU-2513 K&N replacement air filter is a simple performance add-on for 2013, 2014, or 2015 Suzuki GW250 Inazuma models

Until recent years the selection of sportbikes under 600cc was about as wide as a throttle cable. Thankfully new riders, commuters, or anyone wanting a small-displacement sportbike have a wide variety of choices at their fingertips these days. One standout from the crowd is the Suzuki GW250 Inazuma which offers excellent handling and fuel economy. Quarter-liter sportbikes have one area where they could use a little assistance, though, namely the horsepower department. Owners of the 2013, 2014, or 2015 Suzuki GW250 Inazuma models can add power and performance with the K&N SU-2513 high-flow replacement motorcycle air filter.

The SU-2513 K&N replacement air filter is an easy-to-install performance upgrade. It’s made with a precision-engineered durable urethane sealing lip to be a perfect fit in the factory air box. Designed to increase horsepower and acceleration, this Suzuki GW250 Inazuma replacement air filter incorporates K&N’s famous oiled-cotton gauze air filter media for excellent air flow and outstanding engine protection.

The variety of performance air filters is just as diverse as the current assortment of quarter-liter sportbikes. However, when it comes to performance air filters, the choice is simple. The K&N SU-2513 performance replacement air filter stands out from the crowd, just as the 2013, 2014, or 2015 Suzuki GW250 Inazuma will do.

K&N Filters Talks With Roland Sands and Gets A Behind The Scenes RSD Shop Tour

The RSD motorcycle collection ranges from post-war British bikes to vintage motocross machines

Some of Roland Sand’s earliest custom motorcycle builds are on display at the RSD studios

Many bikes in Roland’s collection have been infused with his style, while others remain in a period-correct state of existence

Evidence of Roland’s adrenaline fueled motorcycle adventures is lurking in every corner of the RSD studios

Roland Sands Design products are developed in house from concept, to rapid prototype, to the final design

Behind doors at RSD which read “Employees Only” is an eclectic world of motorcycles and memorabilia

The projects on this particular visit to the Roland Sands shop include a BMW GS Adventure, a BMW r9t, and a BMW S1000RR

Beyond the bikes and bling is the RSD shop where custom bikes are built from start to finish

Roland Sands is a contemporary custom bike builder and motorcycle visionary. The Roland Sands Design studio in Los Alamitos, California calls to motorcycle riders like a beacon promising freedom without barriers plus a dash of style and flare. The RSD studios have become a must-see attraction for those who march to the beat of a different drum. Upon stepping inside the RSD showroom visitors are welcomed to be part of the Roland Sands lifestyle. This RSD influenced way of life transcends typical barriers between brands or styles of motorcycles by simply encouraging everyone to get out and ride. As Roland Sands put it, “Do cool stuff and people will follow.”

While the RSD showroom is a treat in and of itself, few visitors get the full tour of the facility. Behind doors that read “Employees Only” is an eclectic world of motorcycles and memorabilia. The RSD motorcycle collection ranges from post-war British bikes to vintage motocross machines, to some of Roland’s earliest custom bike builds, and a surprising number of Honda Mini Trail 50’s. Many of the bikes in Roland’s collection have been infused with his unique style, while others remain untouched in a period-correct state of existence. As Roland said “We probably have nearly one of every brand of motorcycle in the shop, or we’ve touched it in the past couple of years.”

Beyond the bikes and bling is the RSD shop where custom bikes are built from start to finish. On this particular visit to Roland’s shop, it was clear to see how capable the staff at Roland Sands Design can be. Current projects include a BMW GS Adventure, a BMW r9t, a BMW S1000RR a Harley-Davidson XR750 race bike and a one-off frame cradling an Indian Motorcycle engine like those found in the Indian Scout. “It’s a real evolution of styles and we’re forced into evolving every day,” said Roland Sands. The team’s work doesn’t end there. All Roland Sands Design products are developed in house from concept, to rapid prototype, to the final design.

Of course, all work and no play would make Roland a dull boy. Evidence of Roland’s adrenaline fueled motorcycle adventures is lurking in every corner of the RSD studios. Posters on the walls, thrashed riding gear, a TV in the showroom, and even the bikes themselves serve as a reminder of Roland’s high octane antics. Roland’s bikes are built for the ride and the writing on the wall proves it. Well-worn grips, foot pegs that have kissed the pavement and filthy air filters prove that his bike builds aren’t trailer queens. When you ride a bike hard, like Roland does, proper maintenance and excellent motorcycle air filter performance is crucial to staying rubber side down. “The only filtration we put on our bikes is K&N. That’s it. I’ve used K&N for a real long time. It’s always been a great product; it’s a product you can believe in. We put it (K&N) in all of our filtration products we sell through the RSD brand,” said Roland Sands.
