#162 SR400Custom Report

This is a full custom bolt-on hardtail based on the SR400.

The style of vintage British bikes, the detailed design, and the pursuit of speed are the basis of the production image, but in order not to be just a replica of something, we have made it so that it can be ridden hard as an original custom of the Japanese SR, which is supported by old car lovers and custom lovers.

Originally, it was “Custom Gallery No. 20“. The owner of the cafe racer style SR400, which was produced in the early days of 2%ER, started with the words “I’m tired of the clip-on handlebars. I want to ride a bike without getting tired”.

So it’s a custom bike without rear shocks, incorporating the “Rigid Line Bolt-On Hardtail Kit SR400/500“, but the angle of the seat urethane and seat springs, the position of the handlebars, and the “Mid-High Step Kit Chrome for SR400/500” are prioritized for comfort and fatigue resistance.

The style is “like an American bob-jobbed a Vincent, a high-end British car from the late 40s, with a transparent adult transparency, a styling that looks fast, and a presence that stands out without being too conspicuous in the countryside or the city”. This was the image we had in mind when we created it.

Following the manufacturing methods of the time, each part is hand-finished. The theme was also to create a vehicle that exudes the warmth of handmade, like an old car.
