#117 SR400Custom Report
A chopper SR that embodies the style of the 60’s and 70’s.
Based on the “STD Hardtail Complete“, we added a lot and finished it in the owner’s ideal B-class chopper style.
Although it is a frame with a smart triangular silhouette like a rigid frame, the rear section uses the “Rigid Line Bolt-On Hardtail Kit SR400/500” kit.
By replacing it with a swing arm, you can easily pass the vehicle inspection. The overall silhouette was created by extending the fork by 30cm and changing the rear to 16 inches.
