#296 SR400 PURPLE BLURRYCustom Report

This is an SR400 that was exhibited unpainted at the 2023 NEWORDER Chopper Show, went on a 3100km tour of Hokkaido as it was, then had its finishing paint done and was exhibited at the 2023 Yokohama HOTROD CUSTOM SHOW.

This vehicle was not made to order for a customer, but was made for the 2%ER store owner in a hardtail specification. It not only has the looks of a 70’s long fork chopper,

We focused on ride comfort and handling, and created a position that is easy to ride without being intimidated by the look, from city riding to long touring,

We made it with a proper handling level that anyone can ride.

 

The rear brake is a “SR400/500 Rear Disc Kit” that is under development and also serves as a product test, with two calipers for the right hand brake,

The right foot brake is used separately for each system, which makes the front area around the chopper, which does not have a brake on the front wheel, clean.

The hand brake operates the master cylinder installed at the rear of the engine crankcase with the drum brake wire,

It is a safe specification that you can feel safe even when stopping on a slope or driving at low speed.

 

Although it is a vehicle that was exhibited at the largest custom show in Japan, it is not positioned as a show bike, but is finished as a practical custom vehicle that can run firmly.

Considering the later vehicle inspection, the hardtail kit and rear disc kit are bolt-on designs. The rear can be changed to a swingarm/rear shock specification with bolts/nuts.

●【Trail Value】

When a 30-inch (about 75cm) over long fork, custom-made by a certain overseas manufacturer, is installed as is, it becomes extremely heavy, and the handling, which becomes like cutting off with a bang just by turning the handle a little,

The trail value is set to about 8cm, which is appropriate, with a 5° rake triple tree made one-off. The handling is set to be neutral, almost the same as the original SR.

It is designed to be easily driven with one hand.

 

Also, by making the front wheel a small diameter of 17 inches, the change rate of the contact point between the tire and the ground when the handle is turned is suppressed.

With these two points, you can easily drive without the handle cutting in at intersections in the city at low speeds and when stopped.

●【Center of Gravity of the Vehicle】

By bending the ○ part more than the usual “rigid line” bolt-on hardtail kit,

The position (center of gravity) of the engine and crankshaft, which are the heaviest in the vehicle, is aimed at the limit where it does not scrape the ground when the vehicle is tilted in a curve,

The center of gravity of the entire vehicle is lowered as much as possible by bending it as much as possible.

By bringing the center of gravity closer to the straight line of the front and rear axles, the wobbling during driving is prevented and stabilized.

Also, with the appropriate trail value and the extended wheelbase due to the long fork,

It provides outstanding stability, especially on bypasses and highways.

●【Brakes】

Double caliper brakes. By changing the lever ratio of the hand brake and foot brake,

It is set to about 4:6. It is finished to be easy to ride by setting the braking to be rear-oriented, which is suitable for choppers.

【Welding Method for Gasoline Tank/Main Frame】

We weld the particularly crack-prone SR400/500 tanks and frames in a unique way. Please click on the image.

【Molding/Painting】

The bond work of the gasoline tank and the entire vehicle body is done by Kyoto’s “P.H.K“, and the painting is done by “BACON“. A psychedelic pattern layered many times. It was finished in a purple-based paint.
