Part of the frame is for the SHOTGUN 650, and the main frame is handmade.
Based on the new model “SHOTGUN 650” released by Royal Enfield in 2024, this custom bike is called “SAMURAI” and was created by Takuya Aikawa, the representative of the custom factory “SURESHOT” based in Yachimata City, Chiba Prefecture.
The exterior, inspired by Japanese samurai, exudes a dignified atmosphere while creating a unique atmosphere that evokes the feeling of “wabi-sabi” (Note 1).
*Note 1: Wabi-sabi is a uniquely Japanese aesthetic. It refers to the feeling that modest and simple things have charm.
The bike uses a frame from the SHOTGUN 650 in some parts, with the main frame handmade by Aikawa. The distinctive rear loop frame is a one-off creation, with subtle changes made to the pipe diameter, width, bending angle, etc. The exterior is a combination of one-off machined aluminum parts and sheet metal parts, resulting in a compact form.

The rear shock is a link-type monoshock designed by Aikawa himself, with the rear shock unit located under the seat.
The front and rear wheels are different diameters, 21 inches in the front and 16 inches in the rear, and are original machined aluminum wheels. The front tire is a DURO 3.25-21, and the rear tire is an ultra-wide slick tire for drag racing. The front and rear brakes are disc type, with the front adopting an inboard disc structure with a disc brake built into the hub in the center of the wheel.
