#345 SR400Custom Report

This is a standard long fork style SR400, assembled entirely with bolt-on parts.

From our experience of creating numerous fully customized SRs, we have crafted original bolt-on design parts that offer a cool look with a well-balanced overall design, a reasonable price range compared to fully customized vehicles from the frame, a step position that doesn’t tire you out even over long distances, a comfortable seat, and operability including handling and jockey shift. The rear fender is our new Frisco fender kit.

The chopper style is also a major point, as it can significantly ease the vehicle inspection process compared to vehicles with modified frames.

Custom List

FrontHandlebars, F forks, headlights, etc.

● This is the longest bolt-on extension that can be assembled without disassembling the front fork, extending the front fork with a 17.5cm joint. The handling, which tends to become heavy due to fork extension and rear lowering, is corrected to make it fun and easy to ride even in city riding with tire selection. While using the standard headlights and turn signals, they are installed in a position where they can be cleared as they are without any position changes during vehicle inspection.
