Ra­dial brake calipers were first de­vel­oped by Brembo for use on sin­gle seat race cars in 1982 and were first tested on a 500GP bike way back in 1992. How­ever, the idea didn’t catch on in the two-wheeled world, and the first GP team to use ra­dial brakes for a full sea­son were Aprilia with Valentino Rossi, Tet­suya Harada and Loris Capirossi on their RS250 GP bikes in 1998. So ef­fec­tive was the sys­tem, that for 1999 nearly the whole of the 500GP grid had dumped con­ven­tional calipers and started us­ing ra­dial ones, a trend that has con­tin­ued to this day. They are now on most road bikes – from bud­get scoot­ers right through to the most ex­pen­sive su­per­bikes. The first stan­dard pro­duc­tion road bike to use a ra­dial calipers was Aprilia’s 2002 RSV 1000 R. They im­prove sharp­ness and feel as the caliper mount­ing bolts run per­pen­dic­u­lar (and not par­al­lel) to the wheel axle.

Ra­dial calipers are now ubiq­ui­tous
