1981 Ironhead Sportster Bobber

Thank God There's Harleys . . .

Our friend "Boomer" from Clarkston, Michigan, United States made available these pictures of his awesome 1981 Sportster Bobber which has a 79 ci Stroker Ironhead engine in a Paughco hardtail frame.

Boomer: "I built this bike to take to Daytona. It rode great (it is fast as hell), got featured in a magazine and it was a lot of fun. But the plan always was to sell it when I got back home. I hadn't been in Daytona in a few years so I thought it would be a blast to build a little hotrod for this years trip.

It is based on a Paughco rigid frame. The engine is a built and stroked Ironhead (now is 79 cubic inches). I found a set of vintage mags (both front rims) and mounted some board track tires for a fat tire look. The rest of the bike is the bare minumum - only things that make it go or make it stop."

Front Brakes Setup

Boomer: "I particularly like the front brake setup on this bike. I used a stock control mounted under the triple tree to run the twin front calipers. The control is linked to a brake lever on the handle bars via a cable. This allows for a very clean set of bars (sort of a BMX look) while maintaining the functionality of front hydraulic brakes.

This bike needs those brakes too!"
