{"product_id":"zodiac-710011","title":"Harrison Billet Billet 4 caliper + Y-bracket 11.5\"","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eHarrison Engineering was, back in 1986, one of the first companies to design and develop a multi-piston aftermarket caliper for Harley-Davidson motorcycles. Each fully progressive 4 or 6 Piston caliper is precisely CNC machined from lightweight blocks of aircraft quality aluminum alloy. To keep the internal tolerances to a minimum, the caliper pistons are machined from special low expansion aluminum alloy and have a hard anodized finish that has the same anti-wear properties as hardened steel. For maximum performance the calipers have one pad for each piston. Harrison claims this gives a more ‘leading edge bite' on the disc than any two pad, or differential bore calipers. It is also especially beneficial in wet conditions, because the first set of pads sweep water off the disc, while the following 2 or 4 pads are still ‘biting' on the disc. That removes the effect of the calipers ‘skating' on the disc, and then braking sharply and suddenly when the disc becomes dry. They are truly progressive calipers, with a direct and sensitive relation between the amount of lever pressure, and the amount of braking power. These show polished or black anodized calipers not only have ultimate stopping power, they also have the ultimate looks, and are available for almost all models. The front calipers bolt straight to the front fork bottom leg, and the rear sets include the mounting bracket. Stainless steel shims, to space the caliper to the disc, and mounting bolts are included with each kit. The front as well as the rear sets are available in both 4 or 6 piston versions, as well as polished or black anodized. Matching design brake rotors can be found elsewhere in this catalogue. All Harrison Billet calipers are approved, and come with a limited lifetime warranty on piston wear\u003cstrong\u003e.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWe have created a Sportster frame with the same sleek design as our Wide Tail Softail frame. The Sportail frame features a \"Stretched Low-Rider\" look, is made from thick wall quality tubing and TIG-welded for improved strength and road holding without disturbing the lines. To obtain the sleek stretched Low-Rider look the steering head is raked to 38 degrees. This requires a 4\" to 8\" overstock fork depending on the wheel and tire size used. The engine is located with no offset in the frame and a rear frame section wide enough to accept extra wide tires. The Sportail SuperAss, is wide enough to take up to 250 wide rear tires. In combination with final belt drive. The SuperAss requires an off-set front pulley or a spacer behind the front pulley. Pulley cover requires spacing. The length of the frame requires the use of a drive belt with approx. 135 teeth. Mounts for a Big Twin side stand and Big Twin forward controls as well as 1974 to present Sportster forward controls are welded in place. Stock style Narrow or Wide Glide forks can be used with the frame, it will also accept many other Custom front forks. The frame will take any 1974-1985 Ironhead Sportster engines as well as 4 Speed and 1986-2003 style 5 Speed Evolution Sportster engines. Because of the right hand final drive the stock style Softail oil tank does not fit, therefore our special Sportail style oil tank or a custom made oil tank such as our Custom Round oil tank must be used. The frame is designed to take Softail type parts and accessories such as Flat Side tanks, forward controls, seats and 1989-1999 Softail shock absorbers. Due to the completely different shape of the swingarm a Rigid Frame type rear caliper kit must be used.\u003cbr\u003e\u003cstrong\u003e1989-1999 Softail shock absorbers can be found elsewhere in this section. \u003cbr\u003eNote: \u003c\/strong\u003eZodiac Sportail frames are approved as a replacement frame for Harley-Davidson Sportster motorcycles. They may be used in combination with our approved GCB front forks and\/or any other approved components.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Harrison Billet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Harrison Calipers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cp\u003eBillet 4 caliper + Y-bracket 11.5\"\u003c\/p\u003e\u003cp\u003eOptional parts, Harrison Billet 4 piston Rear Custom caliper kit\u003c\/p\u003e\u003cp\u003eExcept where mentioned differently ALL brake calipers are ABS compatible.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHARRISON BILLET LIFETIME WARRANTY\u003c\/strong\u003e  Harrison Billet brake calipers are top-quality products and besides a twelve month limited warranty on the caliper, they carry a lifetime warranty on piston wear. No matter how old your Harrison Billet caliper is, whenever it shows a piston to caliper brake fluid leak, that is not caused by worn seals, you can return the caliper (freight pre-paid) to Zodiac. It will be repaired at no charge and returned to you freight collect. Warranty will be void when abuse, or poor maintenance of the caliper causes the defect.\u003c\/p\u003e\u003ch2\u003ePart Numbers\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eItem Number:\u003c\/strong\u003e ZPN710011\u003cbr\u003e\u003cstrong\u003eZodiac Part Number:\u003c\/strong\u003e 710011\u003c\/p\u003e","brand":"Harrison Billet","offers":[{"title":"Default Title","offer_id":62715682324867,"sku":"ZPN710011","price":481.62,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/zpn710011.png?v=1790640522","url":"https:\/\/hogparts.co.uk\/products\/zodiac-710011","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
