Superior suspension technology
KYB, or Kayaba Corporation, has supplied the latest MX suspension for Yamaha Motor’s motocross bike, the YZ450F (2026 model). The suspension was designed around the “Ground Hook Concept” to achieve the “ground feel on any surface,” “stable absorption,” and “feeling that allows the rider to attack with confidence” required in the harsh motocross environment. By optimizing the three elements of damping control, friction control, and adjustment mechanism, the suspension responsiveness is brought as close as possible to the rider’s intended operation. KYB’s manufacturing technology has come to fruition as a suspension designed to bring out the competitive power of the YZ450F.
Innovative design adopted for the front fork
The front fork features a leaf valve spring valve structure that smoothly absorbs even small road imperfections, improving off-road performance by providing responsiveness to even the smallest inputs. Furthermore, when a large impact is received, a delta valve exerts its absorbing power to mitigate the impact. Furthermore, with an emphasis on maintainability and on-site adjustability, a tool-less adjuster is incorporated, allowing for quick setting changes during races and practice sessions.
Enhanced rear cushion functionality and improved adjustability
Like the front, the rear is designed to handle a wide range of impacts, from small road inputs to large ones. The large-diameter base valve structure consistently improves absorption during small inputs, while the 6-port piston structure ensures control during large inputs. The rear also features a tool-less adjuster, making it easy to adjust the front/rear balance while pursuing a feeling that is directly linked to the rider’s physical sensations. These designs make the YZ450F’s rear behavior more sensitive and powerful.
Brand statement and KYB’s manufacturing philosophy
KYB values precise quality and reliable technology above all else, and has a brand statement that frankly expresses the characteristics of its products. It believes that reliable quality is a “superiority” for the general public, customers, business partners, and even each and every employee, and that it is important for them to have a “sense of making a difference in the world.” The supply of the latest MX suspension for the YZ450F is not simply a technical offering; it is an extension of that philosophy. It is also a challenge to see how KYB technology can support athletes’ riding and push their limits on the demanding stage of motocross.
The installation of the latest MX suspension on the YZ450F is more than just a spec update. It is equipment that allows the rider to sense the fine details of the road surface and continue to attack by trusting that feeling, and it is undoubtedly a sign of the pinnacle of KYB technology.
