#135 SR400Custom Report
This is a custom job where we transformed an SR400 in a Bobber style, which you brought in, into a “Rigid Line” bolt-on hardtail.
We handled everything except for the egg tank and block pattern tires that were already installed, such as the handle/headlight area, steps, frame processing, urethane paint for the processed parts,
Installation of the brought-in seat, production of fenders, sissy bars, tail lamps, installation/setting of the FCR carburetor, and rewiring of the harness.
The style is a sand racer, a mixture of chopper/bobber/scrambler.
For the maintenance aspect, which was a major concern, we provided detailed overall maintenance in addition to ” 2%ER SR400/500 Vehicle Inspection Maintenance “, to ensure that you can ride safely.
(We do not recommend block tires for street use at 2%ER)
The owner himself will enjoy finishing the surface of untreated parts such as fenders and sissy bars after delivery.
