Description

Good brakes are safety-critical. When Hyosung discontinued the OEM caliper pistons for the ST7 Cruiser, we engineered a superior solution. This kit replaces rust-prone standard steel pistons with UK-made stainless steel versions. This prevents piston seizing issues common with aging bikes, ensuring your brakes operate flawlessly for the lifetime of your motorcycle. This is a vital performance and longevity upgrade.

We justify the premium pricing by offering materials that outperform original components, giving you superior durability and peace of mind.
