GP-PERFORMANCE Full Titanium 4-1 Z900RS (23-) … 253,000 yen Product number: 25-712-02
The classic GP-PERFORMANCE styling has been modified to match the redesigned 2023 model. The exhaust manifold has been changed from 4-2-1 to 4-1. The exhaust pipes have also been redesigned to an optimal length. This improves power output in the high-speed range without sacrificing power in the low-speed range.
The sound has been extended to a low range, making it comfortable for the rider while riding and enhancing their mood. The forward-leaning pipe layout and sound reminiscent of old motorcycles emphasize the neo-classical feel and bring out the charm of the Z900RS. This exhaust is government-certified.

OVER x SUNSTAR Semi-Floating Brake Disc Type A Z900RS (2018-) … 123,200 yen (tax included) Product number: 83-71-51A
A more precise floating system improves strain resistance and prevents deterioration of braking feel. By ensuring a plate thickness of 5.5mm, compatibility with Brembo calipers is improved, resulting in a specification that is more specialized for braking operation.
Demonstrates excellent durability even under harsh conditions. By narrowing the effective pad width compared to the OEM in line with the Brembo caliper support, the outer rotor is made as light as possible, minimizing the weight increase that is a disadvantage of large diameter rotors.
