Throwback Thursday - Hiding in Plain Sight - Part 3 - Motorcycle Man

Meet #19 - TC Chambers
It was about 10 AM when the crowd began to thin out, making it much easier to find a few more hidden gems. That's when I came across TC Chambers and his 1968 Harley Davidson Sprint Tracker. I asked him about the bike and it's history. This is what he told me.

These dirt trackers were the predecessors to today's motocross bikes. In the 60's and 70's we traveled across the US going from one dirt track race to another. You have to remember what the highway system was like back then, sure not like today. Almost every highway was just 2 lanes. We'd convoy overnight to avoid traffic and speeding tickets, 3 to a truck, we'd take turns sleeping and driving."
"I rode for several different factory's in my days, mostly BSA and Harley. Harley imported these from Italy. They were made by Aremacci. Not very many factory parts on one a real factory racer"
"The whole bike was made for one thing, racing. We got all of the parts through Harley, except fort the frame. The frame was made by Sonic-Weld. It was also the most expensive part of the bike. Harley started making a mass produced design a few years later, for a fraction of the cost, so you don't see a lot of these around anymore."
The whole bike weighs in at 180 lbs (that's about 80 lbs more than the average walk-behind lawnmower).  Everything except the tank and seat is alloy to keep the weight down. They are also the only painted parts on the bike. 

"Dirt tracks would chew everything up, so the fewer painted parts, the better. The frame's not chromed, it's nickle-plated. Chroming it would have made the frame brittle."

"We carried a a big supply of rear sprockets. We changed them to match the length of the track. Sliding through the turns meant we couldn't shift, so we'd get in top gear as fast as possible, spin it up to 10,000 RPM, and hold on.

"No brakes either. Even if there were, they wouldn't do much good on dirt.The only way to to slow down or speed up was to use the throttle."

I asked TC if he was still racing. "No, I gave that up a long time ago, but I still ride a Harley almost every day."
We both had to chuckle when we heard the conversations of some passers-by. "What's the red button for?", asked one fellow. "That's the horn...it wouldn't be street legal without it."
Controls were as simple as possible, clutch, kill switch, tach (tape marked at 10,000 RPM), and throttle.
