Designed for select KTM motorcycles, this rebuild kit includes the piston or pistons required to rebuild one caliper. It is a practical replacement for worn, corroded, or damaged original components.\u003c\/p\u003e\u003cp\u003eThe piston is precision machined from high-grade 304 stainless steel for excellent durability and corrosion resistance. Stainless steel reduces thermal conductivity by up to 93% compared with aluminum, helping limit heat transfer through the caliper during demanding riding. This design also avoids common issues associated with plastic composite pistons, which can become brittle with age, as well as OEM chrome-plated steel and aluminum pistons that may corrode over time. The kit also eliminates failure-prone ceramic inserts found on some KTM models.\u003c\/p\u003e\u003cp\u003eFitment includes the 2001-2005 KTM 125 EXC, 2001-2002 KTM 250 SX, 2001 KTM 250 SXS, and 2001-2002 KTM 400 EXC 4-Stroke. Verify the model year, motorcycle model, and caliper application before installation. The All Balls 18-9004 kit is intended for rebuilding one caliper and is suitable for maintenance, restoration, or replacement of deteriorated brake piston components.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePrecision machined from high-grade 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eReduces thermal conductivity by up to 93% compared with aluminum\u003c\/li\u003e\n\u003cli\u003eResists corrosion associated with OEM chrome-plated steel and aluminum pistons\u003c\/li\u003e\n\u003cli\u003eProvides a durable alternative to plastic composite pistons that may become brittle with age\u003c\/li\u003e\n\u003cli\u003eEliminates failure-prone ceramic inserts found on some KTM models\u003c\/li\u003e\n\u003cli\u003eIncludes the piston or pistons needed to rebuild one caliper\u003c\/li\u003e\n\u003cli\u003eFits select 2001-2005 KTM 125 EXC, 2001-2002 KTM 250 SX, 2001 KTM 250 SXS, and 2001-2002 KTM 400 EXC 4-Stroke models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2001 KTM 125 Exc\u003cbr\u003e\n2001 KTM 125 SX\u003cbr\u003e\n2001 KTM 200 Exc\u003cbr\u003e\n2001 KTM 200 Mxc\u003cbr\u003e\n2001 KTM 200 Sx\u003cbr\u003e\n2001 KTM 250 EXC\u003cbr\u003e\n2001 KTM 250 EXC-G Racing\u003cbr\u003e\n2001 KTM 250 MXC\u003cbr\u003e\n2001 KTM 250 SX\u003cbr\u003e\n2001 KTM 250 SXS\u003cbr\u003e\n2001 KTM 300 EXC\u003cbr\u003e\n2001 KTM 300 MXC\u003cbr\u003e\n2001 KTM 380 Exc\u003cbr\u003e\n2001 KTM 380 Mxc\u003cbr\u003e\n2001 KTM 380 Sx\u003cbr\u003e\n2001 KTM 400 EXC 4-Stroke\u003cbr\u003e\n2001 KTM 400 MXC 4-Stroke\u003cbr\u003e\n2001 KTM 520 EXC 4-Stroke\u003cbr\u003e\n2001 KTM 520 MXC 4-Stroke\u003cbr\u003e\n2002 KTM 125 Exc\u003cbr\u003e\n2002 KTM 125 SX\u003cbr\u003e\n2002 KTM 200 Exc\u003cbr\u003e\n2002 KTM 200 Mxc\u003cbr\u003e\n2002 KTM 200 Sx\u003cbr\u003e\n2002 KTM 250 EXC\u003cbr\u003e\n2002 KTM 250 EXC-G Racing\u003cbr\u003e\n2002 KTM 250 SX\u003cbr\u003e\n2002 KTM 300 EXC\u003cbr\u003e\n2002 KTM 300 MXC\u003cbr\u003e\n2002 KTM 380 Exc\u003cbr\u003e\n2002 KTM 380 Sx\u003cbr\u003e\n2002 KTM 400 EXC 4-Stroke\u003cbr\u003e\n2002 KTM 400 MXC 4-Stroke\u003cbr\u003e\n2002 KTM 520 EXC 4-Stroke\u003cbr\u003e\n2002 KTM 520 MXC 4-Stroke\u003cbr\u003e\n2003 KTM 125 Exc\u003cbr\u003e\n2003 KTM 200 Exc\u003cbr\u003e\n2003 KTM 200 Mxc\u003cbr\u003e\n2003 KTM 250 EXC\u003cbr\u003e\n2003 KTM 250 EXC-G Racing\u003cbr\u003e\n2003 KTM 300 EXC\u003cbr\u003e\n2003 KTM 300 MXC\u003cbr\u003e\n2003 KTM 450 MXC 4-Stroke\u003cbr\u003e\n2003 KTM 525 EXC 4-Stroke\u003cbr\u003e\n2003 KTM 525 MXC 4-Stroke\u003cbr\u003e\n2004 KTM 125 Exc\u003cbr\u003e\n2004 KTM 250 EXC-G Racing\u003cbr\u003e\n2005 KTM 125 Exc\u003cbr\u003e\n2005 KTM 250 EXC-G Racing\u003cbr\u003e\n2006 KTM 250 EXC-G Racing","brand":"ALL BALLS","offers":[{"title":"Default Title","offer_id":67551719653611,"sku":"21-89004","price":25.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/51c6-6182d339c0b71.png?v=1790722789","url":"https:\/\/ctracingservices.com\/products\/all-balls-brake-caliper-piston-kit-18-9004-for-ktm-125-exc-250-sx-250-sxs-and-400-exc","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
