American V-Twin
Spyke Inc has acquired all assets, including intellectual property, inventory, machinery, tooling and molds of STD Development, a 30-year-old American manufacturer of aftermarket engine components for American made V-twin motorcycles.
All of the original STD tooling, CNC machining centers and inventory has been relocated to the Spyke complex in Downey, Calif.
Production has already begun on the popular pan/shovel cylinder heads and STD replica cylinder heads. Engine cases and inner primaries are undergoing a final design review prior to “making chips” and will soon be followed by heads, engine cases and primary components for later style engines.
The initial releases of pan/shovel heads and STD replica heads are available as raw castings, fully machined castings, and fully assembled heads with various upgrades to valves, springs and cylinder head porting.
The STD heads are available with spigot style or three bolt exhaust ports, inside or outside oiling and are supplied to match the customer’s cylinder bore requirements. Optional show quality polished finish in the ports, chambers and outer surfaces make these heads works of art.
