Let’s begin by looking at the obvious inclusion. The redesigned one-piece rocker cover, which not only gives the bike its name, but was also meant to put an end to the rocker leaks that plagued the rocker..The other problem that hounded its predecessor was, of course, overheating. The new oval pie-tin covers sat on top of the second significant innovation, cast aluminum alloy heads.

With huge cooling fins cast into the alloy heads, their ability to dissipate heat was head and shoulders above the old Knuckle. This mix of alloy heads and cast iron cylinders brought about its unique problems though. Cast aluminum has a thermal conductivity rating of 160, while cast iron comes in at a mere 52. This difference resulted in the cylinder head heating up and dissipating heat three times faster than the cast iron barrels. The outcome being oil leaks, with gaps created in the gasket surface as both metals react to heat.

In its first year of production, the Harley-Davidson Panhead was available in 61ci and 74ci options. The harder working 74ci engine was producing around 50hp and featured a more robust twin-gear oil pump outboard of the crankcase. During its 18-year production run, the H-D Panhead introduced some of the factory’s most landmark designs and model names.

By the time the Pan was in its second year of production, Harley had waved goodbye to springer forks. The replacement was the cowl-covered hydraulic fork, which they named the Hydra-Glide. A visual reference that still graces Harleys 70 years on.

When the war was finally over, the GIs came back to a rapidly improving national highway system. The new riders had the income to pursue touring and leisure on two wheels, and the desire to do it on Harley-Davidsons.

This bike has an updated brake change to be more modern and safer with disc brakes added. A rear passenger seat and pegs make the ride enjoyable with a friend. A few other fun small things have been added. Come into the showroom today to check out your next purchase.
