#176 SR400Custom Report
This is an SR400 that we are slowly and steadily building, based on an order from an owner who travels a considerable distance on a single tour.
We are incorporating almost all of the select parts from ” No.9 STD Chopper Complete “, but instead of completing it all at once with a complete order, we have been customizing it little by little with day-to-day work, carefully planning in advance to match the timing of the owner’s visits from afar several times a year, and it is still in progress.
The style is a B-class chopper with a suspension that retains the normal tank, just like an SR.
We are building it according to the owner’s wishes, with a menu typical of a B-class chopper at the time, such as extending the front fork, up handle, sissy bar, and keeping the normal tank for its advantageous gasoline capacity for long touring.
We will continue to evolve, but for now, we have shaped it as a sample of a chopper style without any modifications to the frame and with the normal tank as it is, so we have posted it in this custom gallery.
With the extension of the fork, the straight-line stability is increased, and it is a custom that is particularly suitable for long touring, with a seat and step position that is less tiring, and a sissy bar that can comfortably load luggage for several nights.

• The front area has been transformed into a long fork, just like Chopper. It’s a total of 30 cm (12 inches) over. The handling, which tends to get heavy when riding in the city with a long fork, is cleared by selecting a round 3.00 size for the front tire.
