#97 SR400Custom Report
A B-class chopper assembled entirely with bolt-on parts.
With the new SR400/500 10cm long inner tube and 15cm fork joint, the front is lifted, and the rear is lowered with the 280mm Low Down Suspension] G-SUSPENSION280 [Chrome] General-purpose #SR400/500. We created a B-class chopper silhouette with a belly-up look, combined with a down fishtail muffler characterized by its drooping exhaust pipes.
Despite the long fork style, the selection of front tires and rear shocks, and the Old School Double Seat SR400/500 allow you to wait and ride without stress. Long touring with luggage tied to the sissy bar is particularly easy and tireless.
