2022 MMC SR1

What was your intended objective when you started the build?

The main goal was for me to develop a prototype in view of manufacturing the bike in small series in the USA and in a way live the American Dream. For info we ride vintage Harleys and drive hot rods. My goal became also the life project of my son whose real passion is to design, engineer and build performance parts

What motivated you to start your project?

Initially I just wanted to do a Father and Son project by putting a HD engine inside a Voxan (1995-2009 French Motorcycles Manufacturer) frame. I bought a Voxan and a Buell S1 engine, but considering the challenged, my son Jimmy proposed to design and build the frame from scratch. He is a mechanical Engineer and Race Mechanic, so I was confident and gave him the green light. In 2019, Jimmy gets diagnosed with a lung cancer and because of chemo constraints had to leave his job. What was a week-end project became a life project for him.

What was the most unique and creative thing you did to the bike?

The whole bike. It’s not another modification it’s a pure creation. We started the project with the engine only and made a photogrammetric scan in the garage with a cellphone. Everything around had been designed and engineered by Jimmy up to some bolts and nuts. Just to mention the main parts:

– AL 7075 T6 frame front block that contains the air cleaner and of course the column with the air inlet in the front around it

– AL 7075 T6 rear block that serves as oil tank but also engine, swingarm and shock mount

– AL 7075 T6 column and rear wheel axle

– AL 7075 T6 triple trees

– 4130 frame tubes bolted to the front and rear blocks

– 4130 single sided swingarm

– 6061 sub frame, headlight, foot control brackets, etc.

– Under Engine compression rear shock absorber

– Handmade Aluminum air box, gas tank and rear seat

– Electronic ignition

– Primary belt drive

– Motogadget box

– CCC hidden controls

What are you most proud of?

Our first reward was when we received our first CNC parts (front and rear block) designed by Jimmy. We could finally see the result of his work and start the built. Then came the win at the AMD European Championship, a reward that came after 3 years of hard work and pain due to Jimmy’s cancer. This win made Jimmy confident in his work quality and capabilities and gave him the motivation to keep on going in designing more bikes. He started as an amateur in a garage and was finally considered as a professional by the builders’ community after his win. As the father, I am obviously very proud of him

What do other people say about your motorcycle?

When presenting the bike for the first time @ the AMD championship people said we are coming from another planet. Some professional competitors said that, as soon as they saw our bike, they knew they had no chance to win. The best compliment is when I was given the prize and said my son is not a professional, the bike show organizer said that HE IS.

  Thx Bryan. Indeed a lot of engineering and design and custom fabrication. Not just taking parts and assemble like most do. Hope to be able to comme to Daytona next year.

i do CAD and engineering, ( 3 concept sketches in with H-D ), but usually i do other stuff….
but i am so poor i just had build my custom on $6,000 Total … it’s modified engine parts, modified stock, and some i custom fabricated….
but when you design something from the ground up, like yours, putting together the one off parts ( which cost the most ) are your insurance against mistakes and prof of concept…THEN YOU HAVE TO DO A PRODUCTION RUN TO RECOUP ….. Excellent Work, absolutely gorgeous machine, you son getting cancer is all the prof i need that there is no god.
