About Jim Davis

At two, Jim Davis begged his Dad to put a chain saw engine on his push-scooter “motorcycle”. At 10, he got a Honda Z-50 and customized the handlebars. In his 20’s he completely covered his Norton Commando in python skin and rode it across the US. You get the picture; Jim was born with a deeply embedded motorcycle gene.

After earning engineering degrees and holding down RJ’s (real jobs) in the über competitive world of silicon valley high technology, Jim decided to ditch it all and put his vision and unfettered imagination to work creating truly unique motorcycles.


Never satisfied with the status quo, Jim has the imagination and the confidence to conceive of and to try what has never been done; and the analytic ability and perseverance to refine and see his idea through to fruition. He believes there are others like him who value exclusive, esoteric bikes that really do stand out from the crowd-radical but eminently rideable.

Of course he still enjoys riding on the street, track and dirt, and occasionally widens his motor enthusiasm to four wheels, driving real race cars and participating in the ever ridiculous 24 Hours of LeMons racers.

Current Status

However, it’s been several years since Jim effectively back-burnered the custom boutique motorcycle fabrication business of MotoMorphic.  He decided to spend time with his family, as he has two daughters, so he stopped building motorcycles.

Subsequently, his knee required some major reconstructive surgery, and he is not on a bike since—its been a bit more than 3 years.Although Jim’s current status is retired but I was very much excited to talk with him and know how he created this marvelous innovation called as “JaFM”.

Listen to his entire podcast on how he created JaFM.
