Japanese Custom Culture

Here is an original series "JCC" stands for "Japan Custom culture" written by Webike Japan. There is no doubt that Japan has one of the best and unique custom parts and its culture in the motorcycle industry, but the language barrier has led to the closure of JDM motorcycle culture to the outside of Japan. Through this JCC contents, we present you one of a kind custom and mods bikes by professional craftmen and enthusiasts who just can't stop loving motorcycle.



Launched in 1986. The GSX-R1100 was built with the name of the fastest in the world. While modern SuperSport Bikes are built with a compact chassis in an attempt to centralize mass, the GSX-R1100 was designed outside the framework of racing rules. It recorded a top speed of 265 km/h, which is an amazing feat considering that this was in 1986. This gene was later passed on to the Hayabusa.


JB-POWER's GSX-R1100 is surprisingly mild, with an easy-to-handle engine and not-too-high suspension.


The engine is torquey even in stock form, but tuning has made it even easier to handle and more powerful. The 1052cc oil-cooled engine was bored up to 1316cc by COSWORTH piston kit.

Intake & Exhaust


The FCR carburetor advanced pre-setting is performed based on data accumulated from many riding tests on both track and street. A bearing is used in the throttle actuator to achieve a significantly lighter operating feel. Inheriting the traditional high-efficiency venturi, overflow loss is reduced, enables increased power at high rpm and the diaphragm type acceleration pump enables powerful acceleration.


The 4-1 exhaust system was bent by Mr. Bito, president of JB-POWER, himself. Ultra-thin titanium with a thickness of only 0.7 mm has resulted in a lightweight product with outstanding performance, beauty, and sound quality.



Exquisite braking response due to the body configuration of the highest quality ductile cast iron disc and machined aluminum inner body. Radial mount brake calipers made by JB-POWER with bracket, AP-RACING brake master cylinder is also installed.


The white wheels restore the flavor of the JDM motorcycle in the 80s. As the name "MAGTAN" suggests, the wheels are made of magnesium, which is even lighter than aluminum at 67% of its weight, or about two-thirds the weight of aluminum, and boasts high strength. High manufacturing technology that produces "ultra-lightweight," "ultra-rigid," and "ultra-precise" products has resulted in a higher grade of perfection. Both front forks and rear suspension are set up with exclusive specifications.


Beautiful riding step with hard anodized aluminum finish, 30mm FORWARD/20mm DOWN. The step is retractable for a natural position. Its function, design and finish perfectly meet the riding needs of GSX enthusiasts.


To prevent the risk of "death wobble" from aggressive riding, the Toby Steering Damper is equipped.
