#198 SR400Custom Report

This is a vintage-style bobber ordered from Fukui Prefecture, brought in with a normal vehicle. We used parts as per the owner’s wishes in various places, and assembled it while balancing the overall layout. The aging finish of the entire vehicle, from the exterior, was entrusted to “BACON“, which receives support from all over the world, adding a worn-out atmosphere,

With the front 74 Springer, a setup of front 21 rear 16 inch wheels, bolt-on hardtail kit, jockey shift, and one-off production of exterior parts, we finished a full custom SR400.
