#217 SR400Custom Report
This is a vehicle that was brought in by a young owner from Kyoto Prefecture.
Although it is a 2003 or later SR400, which is not suitable for customization, it is one of the “10 types of complete models” that are made based on the popular SR400/500 with 2%ER,
We produced it in the style of the “B-class Chopper Complete” model.
We left the normal frame, the long fork conversion from the regular menu (30cm long with the optional long inner tube), the Sportster tank, and the front and rear iron style fenders as they were,
This is a custom SR that was finished with the owner’s preferred part selection and additional options within the range of the complete specifications.
The paint color that you can freely choose was painted in glossy black as per the owner’s request.
With options such as a long fork of 15cm or more, select parts, and different paint, we have created a different atmosphere from the sample vehicle.
It is a style that is easy to ride in both long touring and city riding, with increased straight-line stability at high speeds due to the moderate length of the long fork, and easy to fall in curves due to the raised center of gravity of the engine.
