A Bike that Matures with You: YAMAHA SR400 Custom

Webike's Opinion

Here is a "YAMAHA SR400" custom by Webike community user "Kentaro". The exhaust is fitted with a AAA Semi Racing Exhaust, featuring a distinctive tapered megaphone, that delivers increased torque across all speed ranges. With the silencer's highly effective noise reduction, it produces a gentle sound.

To improve handling, a BORE ACE Aluminum Top Bridge processed with a silver anodized finish is installed. This custom part excels in design, performance, and texture, and despite its higher cost compared to other brands, it is worth every penny, providing high satisfaction. In addition, a BORE ACE Special Stem Kit is also used. This kit changes the trail, improving stability at high speeds as well as when leaning into corners, making for a more enjoyable riding experience. The seat is a Brooklands Corsa Single Seat, reflecting the brand's expertise in vintage British motorcycles its charming tail is reminiscent of a classic bike.

The engine is equipped with a KEIHIN FCR Carburetor with a Factory Mameshiba 95mm Long Funnel that has two added extension adapters, making it even longer, at 195mm. Various resetting has also been applied to the engine, significantly improving overall acceleration. Vibrations from a modified SR engine are intense, often causing the headlight bulb to break. The SPHERE LIGHT LED headlight features an integrated LED bulb, which makes it more resistant to vibration damage.
