U.S. Chopper Board Track Panhead

This is an amazing vintage-styled bike with an equallyamazing story behind the build. Rick Krost developed a special board trackplatform eight years ago, after building bobbers, and restored bikes for acouple of decades. He had a plan, a vintage notion for a product line ofcomponents designed around his board track platform.
 
He developed this chassis around his US Choppers business. He doesn’t consider himself to be a for-hire bike builder, but the boss of a parts/ chassis component company. But he does build a ground-up bike or two each year, either for a customer, or to sell. What sets Rick apart from any other builder is his proclivity for vintage styling and components, then his board track chassis backed his historic direction. In this case, he was approached by a young Navy fireman who was in Afghanistan at the time. 
 
“I’ve been saving for four years,” Gabe Wingard said to Rick. “I’m now ready to order a bike built by you.”

Rick was honored to be the chosen builder by a veteran and a passionate enthusiast. Gabe recently left the Navy after 8 years. He spent one nine-month tour in the Afghanistan theater aboard the USS Comstock, an LSD, landing Marines, tanks and Humvees on the shores of Kuwait. During his tenure as a Navy Fireman, he was assigned to over 150 Iraqi ship boarding parties searching for guns and drugs. After his duty overseas he spent four years in Camp David, Maryland. He recently took a job as a fireman at the Kennedy Space center. When Gabe first met Rick, he was given an assignment, to take images of all of Rick’s recent creations into a Photoshop program and pick the components he wanted incorporated into his one-off build. 
 

   

“A commission was borne from the desire to provide abike commensurate with our name and image while providing a smaller bike torail turns with and afford the ultimate riding experience, while incorporatinga vintage drivetrain, all the while emulating the board track bikes of theteens,” Rick said. “We love vintage stuff!” 

The young Gabe, fresh from the Middle East, flew to SouthernCalifornia from Pennsylvania to discuss the project.  

“Given the fact that we wanted this bike to becomfortable and manageable for Gabe, it had to have a lower seat height,”Rick said. “Traditionally, to accomplish this, bikes are lowered to thepoint that frames smack the pavement in curves.  We wanted to express thespeed and sport of board track racing while being streetable, so low framerails were not a consideration!”

Ricklowered the rear axle height by 2 inches, effectively raising the bottom single-loopcradle, while providing almost 5 inches of ground clearance under the motor.  

“Anyone who has built frames knows that this is a realfeat to accomplish,” Rick said. “This bike would feel at home on anasty hill climb as much as on the board tracks, and laughs at tall speed-bumpsor steep driveways.”

“Secondly, we wanted a short wheelbase. We arrived at 58 inches, which is4 inches shorter than our traditional board track frame, manufactured byPaughco, which have been clocked at over, a very stable, 150 mph.  Goingshorter than 58 is not advisable in our opinion with a Harley.  A Hayabusais at 58.5 inches while a GSXR is 55.5 inches with very advanced wheels andsuspension.”

Rick left the rake at 30 degrees, which shouldallow stability at both higher speeds and enough balance for drop kneecornering, given the shortened rear end.  With the lack of modernsuspension and elevated weight of the Harley drive train, de-raking furtherwould provide a dangerous experience and not be confidence inspiring. With this blend, Rick could create a bike that is a sheer blast to rideand won’t suffer from road limitations, nor end up being a bike that is onlylooked at and not ridden.

“Gabe paid us the ultimate compliment when commissioning us,” Ricksaid. “I wanted to pay him back with a bike that said ‘thank you for yourservice to our country’.”  The real trick was to create a compact,uncluttered machine without gaps, while still housing modern amenities such asdisc brakes, road lights, a battery, etc.  There are a lot of parts, butthey had to fit into a chassis that averaged only 10 inches wide and just over6 feet in length.”

The front end is a late ’30s-early ’40s Harley- Davidson hill climb fork thatcame from an old codger Rick horse-swapped with.  He only had to fabreverse rockers for it and add his subtle touches, like squeezing thePerformance Machine two-piston caliper and bracket between the wheel and forkrails.

“We even had 1/16 of an inch to spare after milling thebracket,” Rick said.  

The U.S. Chopper frame was lowered 3 inches in the back boneand shortened 4 inches in the rear. A support tube was welded to the backbonedue to the 3-inch chop drop.  The tanks were relieved over the top of thePanheads and provided plenty of clearance to prevent hot rocker boxes fromtouching the cold gasoline.  The oil bag was fashioned by hand to fit thisshortened and lowered frame, and it accommodates almost 5 quarts of KendalGolden Nitro 70 wt. which he runs in all U.S. Chopper old bikes.  

The rear fender was hand-pounded by Dan at 7 Metal West outof 0.125 aluminum and shows a tortoise shell pattern underneath.  Rick’shallmark rear fender struts use 1936 Harley saddlebag mounting accessories togive it a fine appearance and finish.  

“I am a stickler for using all authentic OEM vintagedrive trains,” Rick said, “so what you see are tried and trueoriginal OEM parts for the transmission, clutch plates, clutch basket, primarychain, engine and engine components, etc.”  

This classic would not be complete without genuinefloorboards to set boots on.  U.S. Choppers manufactures a bar that holdsthe OEM foot controls to their frames, so that the frame can handle OEM shifterand brake sides or a plethora of aftermarket components, depending on yourfancy.  When riding the streets, nothing is more comfortable thanfloorboards that matches the 1915-styled U.S. Chopper chassis for that period-specificlook and feel.

 
“How does one accomplish all this?” Rick said. “I have greatfriends and business partners.  Without help from Rick Pruess atPerformance Machine, Ron Paugh at Paughco, Keith Ball at 5-BallRacing/Bikernet.com, Mike O’Brien at Pacific Coast Cycles, Oscar, my productionwelder; Jim, my production machinist; Fat Paul, my old mentor (RIP) and therest of the guys, I would not be able to build a bike like this.  It takesthe hard work, experience and effort of a lot of great people who form lifetimebonds with each other as they take on these two-wheel, masterpieces.”

Gabecan’t wait to receive his bike. He’s excited to be working in another creativenerve center. Although the Shuttle program was shut down, Kennedy Center actionis hot and non-stop with a recent Mars Rover launch to set a remote controlledRover on Mars, and a new rocket system is in the works to carry folks intospace.  There is a connectionbetween custom motorcycles and rockets. It’s all about functional creativity.
