#329 SR400Custom Report

A spacy 60’s style created by order from a petite and delicate girl.

In consultation with the owner, we aimed for a 1960s KUSTOM, incorporating elements of American custom cars in various parts,

While interpreting the “near future of the time” in a 2%ER way, this is a full custom made to fit the owner’s physique.

Chrome-plated front and rear wheels that are not usually touched in regular custom, engine finished with clean and transparent surface treatment,

While creating with show quality in both design and finish, such as molding and one-off parts of each part,

Of course, we finished it while balancing the position making that fits the owner’s physique and the fun of riding vehicle making.
