The latest project built, not bought, by Bernd Kirschner at Hola Vespa began with a 1958 Motovespa frame with parts added from a 1949/50 Vespa (see fork link cover from 6-Day racer), plus exhaust and tank fabricated by Bernd..
Bernd with some engine details..
“It’s an original 3-geared motor tuned to 137ccm, drilled original cylinder, 56.7mm nose piston, two channel layout, SIP Vape ignition, 19 Dell’Orto carburetor, big box sport exhaust and Vespa Bachetta optics.”
Clearly a talented and handy guy to know - thanks for sharing Bernd ; )
