For chopper and bobber customs
Seat rail kit for SR400 only

A kit version of the seat rail modification technique used in chopper and bobber customs.

Greatly reduces work time

Just cut the stock seat rail at the specified position and weld, greatly reducing work time.
Can also be used on bikes with already-modified frames

The seat rail sits lower, connecting the main frame to the shock mount with a clean line.

15mm lowering also possible
Packed with features that save the builder time and effort

You can choose from 2 positions for the suspension mount bushing.
When mounted in the lowered position, it lowers the bike by 15mm
(e.g., with 50mm lowering shocks, +15mm gives 65mm lowering)

The included spacers can convert the remaining hole from 14mm to M10
It can be used for mounting turn signals, fenders and more.

For Professional.
Welding and fabrication skills required

Welding required
If the width doesn't match due to frame distortion, etc., the frame may need to be bent, making this a for-professionals product.

FAQ

Q Can you issue strength documentation for passing shaken (Japanese vehicle inspection)?

Regarding inspection, views and results vary by transport bureau, and in the Kansai area near us there have been cases where seat rail modifications did not pass.
(What we were able to confirm is that modifications behind the shock mount are acceptable, but anything in front of that will not pass inspection.)

When we checked with several shops in other prefectures, they reported that it passed without issue, but
depending on the transport bureau, it varies greatly by whether there is a past precedent, and strength application documents are also expected to differ by bureau,
so we determined that we cannot issue documents that will reliably pass. Since it may not pass, we treat it as not road-legal in Japan and do not issue documents. Thank you for your understanding.
