#235 SR400Custom Report

This is a fully customized SR400 that we received an order for, including the base vehicle, from Kagoshima Prefecture. The usual “STD Hardtail Complete” is the base, but it’s a show-class full custom with a narrow triple tree at the front, a mini drum 21-inch kit, a rear 2-size wide chrome rim, an FCR carburetor, a mid-high step kit, a frame all-paint, and a clean finish with chrome and polish on various parts.
We made it skinny with a slightly longer, thinner Sportster tank and a narrow Bates seat, and we particularly focused on the overall silhouette when making it.
The paint was finished with silver pinstripes by Kyoto’s “KAMIKAZE PINSTRIPE“, based on the owner’s preferred white.
We decided on each part and finished it while having many meetings over LINE video calls.
