The All Balls Brake Caliper Piston Kit, manufacturer part number 18-9016 and vendor part number 21-89016, is designed to restore reliable caliper performance on select Honda CRF450R and CRF450RX motorcycles. This rebuild kit includes the piston or pistons required to rebuild one brake caliper, providing a practical replacement for worn, corroded, or damaged original components.
Precision machined from high-grade 304 stainless steel, the All Balls piston is engineered for durability and resistance to common brake-system deterioration. Stainless steel reduces thermal conductivity by up to 93% compared with aluminum, helping limit heat transfer within the caliper. The design also avoids the brittleness associated with aging plastic composite pistons, the corrosion concerns found with OEM chrome-plated steel and aluminum pistons, and the failure-prone ceramic inserts used on some KTM models.
Fitment includes the 2017 Honda CRF450RX and Honda CRF450R model years 2002 through 2010. Verify the motorcycle model, year, and caliper application before installation. This kit is intended for rebuilding one caliper and is suitable for maintenance or repair applications where dependable braking performance and long-term component durability are required.
