#229 SR400Custom Report
This is a custom order we received, including the base vehicle, from an owner in Fukuoka Prefecture who got his license to ride the SR400 made by 2%ER. It’s a dream order for a bike shop, and although the customer is far away, we were able to finish the vehicle according to his wishes, including after-sales support such as greetings to nearby shops that specialize in SRs and explanations of the vehicle, through multiple exchanges on LINE.
We designed a large body that can be ridden in a relaxed position using the newly launched “18cm Long Hardtail Kit”, “Standard Ape bar handle 22.2mm (7/8″)“, and “Mid-High Control Parkerized for SR400/500“, tailored to the tall owner’s physique. We finished it with a full custom, including a Springer fork, F21 inch, and FCR carburetor conversion.
In a style that follows the customs of the 60s, the peanut tank, which tends to stretch when attached to the SR’s main frame, was extended by 2.5cm and made with a high tunnel. We also produced a new product, the “5″ aluminum center ribbed fenders, unpolished“, and attached it in a balanced manner, with the shotgun muffler as an accent.
The overall worn-out atmosphere was finished with a bit of aging processing on the paint and chrome plating parts, thanks to “BACON”, which collects orders from all over the world.
