What started as a passion project between a group of industrial designers has blossomed into a full-fledged bike revamp collective by the name of Auto Fabrica. Applying their expertise to creating custom handmade parts, the English designers craft living, roaring custom vintage bikes. The Type 4 seen above is a generation away from its original state, with AF creating a hand-beaten aluminum tank from scratch and adding new rod-spoked wheels to compliment the exposed Yamaha motor. The build is finished off by a supple suede seat and mint blue tank shell – underlining the Type 4′s handsome throwback aesthetic. Enjoy a look at this fantastic custom above, and head over to Auto Fabrica’s site to learn more about the Essex-based shop.
