Harleys first
Motorcycle Trike called the Servi-Car first
appeared in late 1931 as a '32 model. Built in response to Indian's popular Dispatch Tow three-
wheeler. Previously, Sidecar rigs had been modified for various
commercial applications, but the Forty-five powered motorcycle trike was a better multi-purpose machine.
Both manufacturers offered optional tow bars with the three-wheelers,
which automotive service shops found useful for picking up and returning cars
due for service. A single employee could ride to the client's site, tow the
Servi-Car back to the shop, return the car, unhook the trike and ride back.
The three-wheelers also found wide use as light-duty delivery vehicles and
made perfect meter maid vehicles for city police departments..

Harley Sportster |
|
 |
The
Harley Sportster
era begans in 1957 when Harley Davidson introduced an overhead-valve,
54-cubic-inch engine (883cc). Before that, Harley motorcycles were side-valves
(Flatheads). In 1957, Harley Davidson released the
overhead-valve cylinder heads, which gave the motorcycle increased
horsepower and performance. Today there are many iterations of the Sportster.

Harley Jersey |
|
|
Some Class
That's what everybody will say when you step out in this Harley-Davidson
racing jersey. It's the same jersey the Harley-Davidson racing stars and
hill climb men have been wearing the past few years. The color is a
knockout, dark green body and orange sleeves. It's also got three inch
high letters that will tell 'em a mile off what motorcycle you ride. |
