#240 SR400Custom Report
This is an SR400 that we produced with a vehicle brought in from Gifu Prefecture. Although the base vehicle was heavily customized, we customized almost all parts other than the gasoline tank that was originally installed, at the same time as the request for hard tailing around the rear.
The style is finished in a simple, thin-lined orthodox chopper style. The frame and wheels are semi-gloss silver, and the gasoline tank and rear fender have a one-point pinstripe by “JERK GARAGE“.
As noted in the “CENTER” section, we focused on a comfortable ride that is not easily fatigued by adjusting the seat attachment and step position. In the “REAR” section, we introduce ideas for fun riding and top durability, such as how to attach the rear fender and sissy bar that are prone to cracking due to the vibration of the domestic single engine.
