Kim came across photos of Soviet LSR sidecar motorcycles, with beautiful aluminum fairings. The third wheels qualified the motorcycles in their hand-beaten aluminum fairings for sidecar records.

 Here’s Edgar Ermani’s with EKE-1, and (right) Nikolai Shumilkins supercharged Kometa-3 boxer motorcycle in 1954 (85-90 bhp, 138 mph.) 

Thank you Kim!
