#221 SR400Custom Report
We received a long-awaited order from an owner who has overcome various hardships, and this is a fully customized SR400 that we finished while carefully consulting each part. It is a show-level finish with attention to detail, but of course, it is something we produced on the premise that you can enjoy riding it for a long time in everyday use. The contents include a 13cm long hardtail kit, a narrow triple tree, a newly developed 21-inch mini drum brake kit for this vehicle, a discontinued two-size wide rear 18-inch chrome rim, all paint from the frame, FCR carburetor, engine O/H with gun coating and cerakote on each part, finishing of wheel hubs, polishing and chrome finishing of each part, etc., it is a fully optioned SR400 with many additions to the usual “STD hardtail complete“.
We finished it with a skinny styling that is unimaginable from the usual SR custom, with a narrow triple tree of about 40mm, a narrowed genuine gasoline tank, a one-off handle, a slim and tall sissy bar, etc., like a dragonfly in a chopper style.
In producing this vehicle, we received cooperation in surface treatment from “AWANO Coating”, a friend of the owner and our business partner, “PHK”, and “KAMIKAZE PINSTRIPE”. Thank you very much.
