Webike's Opinion

Here is a "KAWASAKI GPZ900R" custom by Webike community user "Chakoro-kun". This Red Ninja from 1990 features a sleek exhaust extending upward and black lines on the cowling, creating a dynamic, speedy look. The exhaust is from OHNISHI HEAT MAGIC, crafted by a group of artisans specializing in custom titanium exhausts for cars and bikes. The engine is upgraded to a more powerful 972cc with a WISECO Overbore Piston Kit. The front disc rotor has been swapped for a SUNSTAR WORKS EXPAND Front Disc Rotor, enhancing both full-braking control and delicate maneuverability during turns. Additionally, the bike is equipped with SUZUKI Stock Brembo Radial Calipers, known for their high rigidity, which provide stable braking power and excellent control.

The handlebars have been replaced with ones from HURRICANE, a brand known for their craftsmanship that produces a wide variety of quality handlebars with a high level of safety based on technology cultivated over many years. The battery is a SHORAI Lithium Ferrite Battery. Although more expensive than conventional lead-acid batteries, it is about one-fifth the weight, offers high power for excellent starting performance, and is maintenance-free, which is also a nice feature.

The rearsets are NITRO RACING Rearsets made from A2017S duralumin, known for their light weight and high rigidity. Their design ensures proper brake pedal stroke, improving the control of the rear brake.
