“Here is our latest Brawler GT. We finished it this week,” said Dar Holdsworth the boss of Brass Balls Cycles. FXRs are coming back under the signage of the only two custom bike manufacturers left standing in the United States, Brass Balls Cycles and Big Bear Choppers.
What an interesting run since the heyday of 2007, then the financial downfall of 2008. Yet, through it all two motorcycle configurations stood tall, the Bobber and the FXR. The bobber survived because it’s the essence of the chopper world without the frills. It’s the very forerunner of the custom motorcycle. 
After World War II the guys came home and stripped stock motorcycles to give them class, then to start racing, hence the bobber. Here are some shots of the most recent Brass Balls Cycles bobber, built to respect the Navy for the Rolling Thunder Event at the capitol in support of veterans everywhere.
The other survivor is considered the best handling motorcycle Harley ever built. Eric Buell designed it initially.
One company consistently improves on the H-D platform, and that’s S&S. “This Brawler GT has an S&S EFI, T-series (they can't say twin cam for copyright legal reasons) 111-inch motor,” said Dar.  This is the first FXR to boast a Twin Cam powertrain. 
The engine is mated to a 6 Rivera Primo FL style tranny with oil pan underneath. “It sports a Delkron inner primary and Barnett’s Scorpion billet outer primary,” said Dar. “D&D tuned the exhaust with a 2-into-1 system and carbon fiber canister exhaust. Oh, and one of the new S&S Air-1 air cleaners makes the air flow.
Dar is a builder who builds because he loves to ride, he loves any creative exercise, and he loves quality. This Brawler GT represents his notion of the best handling motorcycle product on the market.
Some more featured components incorporated into the Brawler GT include:
“Ohlin's front and rear suspension with our own custom designed & machined fork clamps,” said Dar, “with the top clamp housing our Chrono-classic analog tach/digital speedo.”
Dual Brembo radial calipers with EBC floating rotors.
BST carbon fiber wheels with Avon 3D-XM Storm tires.
Carbon fiber front fender.
“It has our Brass Balls Performance LED headlight up front and rear LED signal lights incorporated into the chassis,” said Dar. “Custom fabricated in house: fuel tank, rear cowling and side panels.”
ISR adjustable hand controls with Brass Balls new Performance leather wrapped billet grips. Motion pro cables.
“Oh, and we have a new relationship with Driven Oils (formerly Joe Gibbs Racing oils),” said Dar. “We will be loading this bike with Driven's amazing performance oils.”
This one is going to our dealer in Shanghai,” said Dar. “Yes, we are exporting American Motorcycles to China.”
Dar has refined his Brawler GT model for three years. “It's the most incredible riders’ bike we've ever created,” said Dar, “and the first person I've given photos to is Bikernet.”
“By the way, I know there is no chain guard on it. We fabricated one from aluminum,” Dar said, “then took it off to use it for making a mold to manufacture units from carbon fiber.”
The Brawler start at $39,995, and this one was outfitted to $51,500. Extreme Brawler Tech Chart

I'm a fan of the Brawler since it first came out and this GT is outstanding, right now its my favorite custom bike out there, handsdown!

Believe me, if I could afford one I would buy it in a heartbeat. I sincerely congratulate Brass Balls for all of their bikes but specially for creating the "beautiful" Brawler GT......!!!

Editor Response Thanks much, I'm sure you made their day.
Spaced out on the above the 2014 version. Can this bike be price competitive to sport bikes.

Just a lower middle class working stiff that EVERYTHING i make goes to my wife and kids.

A lot of guys here in CA are in the same boat as me. I commute 145 miles a day and work at one of the largest glass manufactures in the world.

I would Love to tell everyone that my bike came from Brass Balls Cycles!!!
