Product Description

Racing top bridge designed for the ZX-25R to achieve the best strength balance.

When used on the circuit, it can be removed from the base of the key cylinder mounting area, allowing for significant weight reduction.

While maintaining the rigidity balance specialized for sports driving, it is processed to the utmost limit in wall thinning.

7000 series aluminum alloy is used as the material, and black anodized color treatment is applied.

ZETA titanium bolts are used for the clamp pinch bolts.

  • "Shape to prevent stress concentration"
    The R shape, which eliminates corners as much as possible, disperses stress.

  • "Ti-6AL-4V bolts are used."
    ZETA titanium bolts are used for the clamp pinch bolts. The titanium bolts not only reduce weight, but also provide stable tightening torque and improved visuals.

  • "Rigidity balance specialized for sports driving"
    Width rigidity is reduced by about 35% compared to the stock without compromising the vertical rigidity. The purpose is to allow the vehicle body to flex laterally so that the front forks do not move when the vehicle is banked deeply.

  • "Lightweight"
    The large, thin-walled shape contributes not only to rigidity balance but also to weight reduction: in the case of the RSV4, the stock top bridge weighs 534g, while our prototype weighs 494g, a reduction of 40g.

  • "Factory Look"
    The top bridge with a meatless design used in MOTO-GP and WSBK creates a sense of luxury in the cockpit.
