#302 SR400Custom Report

This is a 13cm long hardtail SR400 that we customized for an auto mechanic in Aichi Prefecture who brought in his own car body.

The wheels are 21 inches in the front and 16 inches in the rear. We extended the front fork by 10cm with a fork joint to balance the overall look.

We used classic parts such as the peanut tank, rib fender, and drag pipe, all set in a balanced position that suits the SR’s vehicle size,

〇 Handlebars positioned with the owner actually straddling the bike

〇 Mid-high step kit that allows for weight distribution

〇 Mounting method for the solo seat, with attention to the angle of attachment and the lever ratio to the spring

We have created a position that suits the owner, who has flexibility in all joints, and a seat that provides higher cushioning than a poorly made short rear shock vehicle,

Not only the looks with a balanced overall balance where each exterior should be, but also the ride comfort is carefully produced.

The gasoline tank and rear fender are by the world-renowned patina painter “BACON“.
