Based in France, Moto Corki was the brainchild of Lucienne Cordonnier. He built his own frames – as noted by Satanic Mechanic it was a backbone design ‘probably inspired by Egli but unlike the Egli and its successors, the backbone extended down to the swingarm pivot in a 110 degree angle.’
Another website suggests that the Corki name came from a combination of CORdonnier and suzuKI, as his first frame design was for a Zook. He built frames for motorcycles and cars, you can check out some examples here.
Lucienne started building frames in 1967 – this example is with a frame that he created in 1979 and it houses a Yamaha 350 RDLC engine. It’s got Jolly Moto exhaust, VForce4 reeds, and BMC air filters. The seller says that it’s “in very good condition” though he’s only used it for one day for “testing.”
