#307 SR500Custom Report

This is an 18cm long hardtail SR500 that we made to order for a barber in Hachioji, Tokyo.

Style

The front fork is extended by 15cm to match the extended wheelbase, resulting in a setup where the body of the vehicle becomes twice as large in a natural balance.

The extended front fork is set with a skinny narrow triple tree,

Combined with a tiny mini drum 21-inch wheel, it is a chopper style with a slim and chopper-like skeleton,

The owner’s favorite exterior parts are well balanced.

Finish

The frame’s metal-like paint is IZ Metal, and the aging paint for the gas tank and rear fender is “BACON“.

Ride Comfort

During the production process, we had the owner come in and actually straddle the bike, and we decided on the positions of the handlebars, seat, and steps to suit the owner’s physique.

The backrest of the king & queen seat has a subframe built into the inner part, allowing the upper body weight to be supported,

Despite the lack of a rear shock on the rigid frame, it is designed to be extremely fatigue-resistant and enjoyable for long rides.

The ride is a combination of an O/H 500 engine and an FCR carburetor,

It is sturdy, resistant to crushing, easy to start and handle, and a fun to ride 2%ER style full custom vehicle.
