Post-Sale Update: This Panther Model 100 with Watsonian Sidecar sold for $5,800 – seems like a very reasonable price!
Introduced way back in 1932, the Panther Model 100 kept evolving until 1963, by which point the Model 120 had taken over.
The Model 100 (and 120) for that matter both featured the distinctive “Sloper” motor, named for the angle that is so evident at a side view. The 598cc single produced 23 horsepower, which was good for a top speed of 70 miles per hour. 1954 introduced a swingarm, four gallon fuel tank, and Panther forks to the Model 100, which was well suited for a sidecar.
This specific Panther Model 100 has had an older restoration but everything is claimed to be functional and in good condition. Obviously, it also has a Watsonian sidecar – the oldest surviving sidecar manufacturer in the world (established 1912). It is being offered by the Grom Motorcycle Museum in Slovenia, which has over 140 motorcycles going back as far as 1906.
