Langcourt Performance Arsenal Racecraft Logo

Langcourt Performance announced today the addition of a new performance division Arsenal Racecraft, to develop performance parts and kits for Harley-Davidson and Indian Motorcycles.  Arsenal Racecraft has some of the best names in the motorcycle world as development partners, Matt Smith Racing, CP-Carrillo Pistons Andrews Cams, and Derek Churchwell of DC V-Twin. 

Arsenal Racecraft is introducing a performance kit for Harley-Davidson Twin Cam 103 C.I. 2007 and later engines. The kit consists of using OEM H-D cylinders coated with our proprietary LP-F1 coating (resulting in increased HP, durability, and heat reduction).

Arsenal has a tremendous opportunity to be an important player in the motorcycle aftermarket industry.

John Silseth

CEO of Langcourt Performance

AR Bullet Pistons developed and manufactured for Arsenal Racecraft by CP-Carrillo a leader in performance pistons. AR Cams developed and manufactured for Arsenal Racecraft by Andrews Cams the leader in performance camshafts. OEM H-D Heads custom ported by 2-Time NHRA Pro Stock Motorcycle World Champion Matt Smith Racing then scanned and replicated on Langcourt’s Rottler 5 Axis CNC with proprietary “Dimple Port Technology”.

DC V-Twin used a stock 2014 Harley-Davidson Street Glide with a VHR Pro Pipe and a SE Heavy Breather as the test bike and the Dyno results were 78.4 HP and 99.5 Foot Pounds of Torque. When the AR-107 kit was bolted on, it went to 131.7 HP and 117.8 Foot Pounds of Torque. That is an industry best 65%+ horsepower, turning a standard Harley-Davidson into a performance machine that has been extensively tested.  This Arsenal Racecraft Performance Kit will provide industry-leading performance with bulletproof durability that will outperform anything else on the market. The company is releasing its performance parts catalog for Indian motorcycles in the first quarter of 2017.

CEO John Silseth stated, "Arsenal has a tremendous opportunity to be an important player in the motorcycle aftermarket industry."

Colbert Seagraves VP of Marketing & Racing Operations had this to say, “As a collective team we have developed a superior product utilizing stock parts and giving the riding enthusiast a better performing ride."
