#197 SR400Custom Report

The SR400 was originally brought in with a custom seat rail drop process and was somewhat complete. We mainly focused on the 13cm long “Rigid Line” bolt-on hardtail conversion around the rear, customizing various parts, redoing the main harness, and overall revising the SR400. By making the rear a hardtail, we were able to achieve a high-quality style.

(This is what it looked like before the rear customization)

  • RearFenders, rear shocks, swingarms, etc.

    • The main focus of this custom order was the rear area. When brought in, the seat rail was a seat subframe with a dropped design, but it was cut once to connect it in a straight line with the rear hardtail kit, and the seat subframe was remade with thick steel pipes. This has significantly improved strength, rigidity, and durability.
