Manufactured from proprietary high-grade 300-series stainless steel, these advanced pistons dramatically reduce heat transfer into the hydraulic braking system, helping maintain consistent braking performance under the most demanding riding and racing conditions.\u003c\/p\u003e\n\u003cp\u003eCompared to conventional aluminum pistons, BrakeTech's ventilated design reduces thermal conductivity by up to 94%, significantly reducing the potential for brake fluid boil, lever fade, and inconsistent braking performance. Twelve strategically positioned ventilation ports on the pad side of each piston create an insulating air gap between the brake pad and caliper body, further limiting heat transfer and promoting more effective heat dissipation.\u003c\/p\u003e\n\u003cp\u003eEach piston features a super-finished surface that improves piston retraction and reduces brake drag. The result is improved brake release, enhanced rider control during corner exit, increased top speed potential, and extended brake pad life through reduced friction and unwanted pad-to-rotor contact.\u003c\/p\u003e\n\u003cp\u003eBrakeTech's exclusive Fluid Maximizer™ design incorporates a reverse chamber on the hydraulic side of the piston, increasing fluid volume behind the piston to further retard thermal buildup and improve overall braking consistency during aggressive riding and competition use.\u003c\/p\u003e\n\u003ch3\u003eFitment Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Diameter:\u003c\/strong\u003e 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Included:\u003c\/strong\u003e Set of 1 piston\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Type:\u003c\/strong\u003e Single-piston caliper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHonda CRF150R (07-21)\u003c\/li\u003e\n\u003cli\u003eHonda CRF250R (04-21)\u003c\/li\u003e\n\u003cli\u003eHonda CRF450R (02-21)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFor Use With FERODO Racing FDB2139 pads\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReplaces factory aluminum caliper pistons\u003c\/li\u003e\n\u003cli\u003eProprietary 300-series stainless steel construction\u003c\/li\u003e\n\u003cli\u003eReduces thermal conductivity by up to 94% compared to aluminum pistons\u003c\/li\u003e\n\u003cli\u003eTwelve ventilation ports help dissipate heat and protect brake fluid from thermal buildup\u003c\/li\u003e\n\u003cli\u003eHelps prevent brake fade and fluid boil under extreme conditions\u003c\/li\u003e\n\u003cli\u003eSuper-finished surface improves piston retraction\u003c\/li\u003e\n\u003cli\u003eReduces brake drag for improved efficiency and increased top speed potential\u003c\/li\u003e\n\u003cli\u003eEnhances brake release and corner-exit control\u003c\/li\u003e\n\u003cli\u003eImproves braking consistency during aggressive riding and racing\u003c\/li\u003e\n\u003cli\u003eExtends brake pad life by minimizing unwanted pad-to-rotor contact\u003c\/li\u003e\n\u003cli\u003eExclusive Fluid Maximizer™ design increases fluid volume to reduce heat transfer further\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Pricing is per caliper.
