Lots of great bikes. More than we expected today. Very few female visitors !! which surprised us. Many of the guys were, I'd say, 55+ years old.
Had to look this one up .... it's a
Matchless.

There were many small and less-famous bikes there. Sadly I did not chat with any owners, so I had to hunt down this one on the internet. It's an "Italjet 50cc Vampire Grand Prix"
The Italjet Vampire was a fantastic-looking small displacement racer produced by this barely-known firm. The Vampire was specifically designed only for race tracks, with a frame made of molybdenum steel and a 'specially prepared' engine. Produced for 3 years, it's incredibly hard to find information on these bikes, let alone actual examples for sale. The engine was a air cooled two stroke with a 13:1 compression ratio that utilized a 20mm Dell'orto carb. Producing 11 horsepower at 11,000 rpm, the factory clocked a top speed of 80.7 miles per hour. Other little tidbits - you got a 4-speed close ratio transmission with a wet clutch, and Pirelli tires front and rear. The whole package weighed just 110 pounds in 'full racing trim'.
