#331 SR400Custom Report

This is our chopper style SR400, made entirely with our original parts such as the new Sportster tank kit.

We have created it as an easy-to-inspect custom with a combination of bolt-on parts without frame modification.

.2° rake triple tree and small diameter, rounded front tire selection greatly reduces the weight of the long fork, resulting in handling,

.Mid-high step that allows weight distribution

.FCR carburetor that makes the SR fun throughout

It’s a chopper style that’s hard to crush, sturdy, not easily tired, and fun to ride.

The faint pattern of the Sportster tank paint and the aging of the entire vehicle is handled by “BACON“.

■Vehicle inspection

.Muffler replacement or core filling

.Change of front blinker position (not wide enough)

.Addition of left mirror

.Add reflector around tail lamp

.Installation of tandem belt and tandem step (when registered for two-seater)

That’s all.

Custom List

FrontHandlebars, F forks, headlights, etc.

●The front fork, which is 37.5cm long, is laid down with a 2° rake triple, and the choice of small-diameter tires not only gives it a chopper-like look, but also greatly alleviates the heaviness of handling when the fork is extended.

【Front Fork Area】

“2° Rake Triple Tree”¥96,000

〇This is an aluminum stem that not only corrects for driving performance and fatigue, but also extends the front wheel forward to enhance the chopper style. The offset of the wheel position (shortening of the trail width) greatly reduces the heavy handling that is common with long forks.
