Replica Frames...the difference is
REAL!
The Construction
V-Twin™ Replica Frames feature steel forgings in neck, front and rear engine
mounts, rear axle plates, swingarm and shock mounts. In this process, the steel
is first fired as red hot ingot, next huge hammers compact and orient the grain
structure into a rough shape of the parts. Subsequent hits form the part into its
final shape, after which it is machined and heat treated which results in increased
strength and resistance to wear. The related components used in construction are
accurately formed stampings and drawn over mandrel seamless tubing which is tig
welded together during final assembly.
