#253 SR400Custom Report

The owner is a female model who is active under the name “Renhi Queen”. This SR400 was ordered as her everyday chopper, which she uses in custom shows and magazines. Contrary to the glamorous image of “Renhi Queen” that many people have, this vehicle is designed in an aged old school chopper style so that she can ride it without any worries in her daily life.

Based on the “STD Hardtail Complete“, the rear uses a 13cm long bolt-on hardtail kit, and the styling is designed to be able to accommodate further long fork modifications in the future. It is finished in a slightly rough silhouette that does not become too smart overall.

Of course, not only the styling, but also the maintenance and ride comfort of this vehicle have been carefully crafted.

The handle is a prototype tiller bar designed with mass production in mind. The high back seat is designed to hold the entire upper body weight by determining the position of the internal backrest frame while the owner is actually straddling it, significantly reducing fatigue in the arms and shoulders due to acceleration G. The design makes it hard to feel the rigid push-up that would normally make your buttocks and waist painful because the area increases and the weight is dispersed. The step adopted is the genuine forward step that comes in a position to distribute the lower body weight effectively according to the owner’s physique.

The gas tank and fender paint, which is based on the race and has a gradation of shades and a bit of aging added, was requested from “BACON“.
