MARVELOUS ENGINEERING's GPZ900R

A unique service called "Ninja Dock" is performed on the Kawasaki GPZ900R to ensure its safe and reliable performance by conducting necessary inspections and maintenance. Furthermore, the owner carefully selects and evaluates the parts to be installed, aiming to create a sense of attachment and fondness towards their bike. They also add a touch of personalization to the finishing paintwork. The bike has an eye-catching exterior paintwork tailored at the YF design, featuring a "Marvelous Pattern" flare. While maintaining a sense of coherence in part selection and engine tuning, each component exudes a distinctive atmosphere.

15 locations were reinforced, and the latest engine was installed. The work began with an internal inspection, and new parts were installed after considering the compatibility and balance of different parts and making selections. The balance of each part was decided after consulting with the owner, and it took about two years to complete the project, achieving a finish resembling a new bike. Many parts were studied, both the engine and the body were assembled, and parts were also prepared to balance out the exterior. Each problem was tackled one by one, leaving no room for compromise, resulting in a high-grade, fully customized bike.
