Of course you need high-quality brake pads and good rotors, but most OEM sportbikes made in the '90s already have those. That leaves braking, and in this area, lever feel and power is everything. Likewise, high-power motors are expensive to build and even costlier to maintain. But suspension setup is rather complicated, even for an experienced racer who has access to a shock dynomometer. The new additions to AP Racing’s master cylinder range will available from regional distributors from March 2017, while product information and technical guidance is available direct from AP Racing, though the technical department on 02476 639 595 or via ENDS.What can we say about a simple brake master cylinder? After all, your bike stops just fine, so why spend $500 on a little thingie with a lever and a bunch of nasty fluid in it? It's simple really: If you want to go fast on a race bike, you've got to do three things better than anyone else - stop, turn and accelerate. The current range of lightweight aluminium alloy master cylinders comprises 12 designs suitable for all forms of competition use.Įach master cylinder is individually shimmed during manufacture to give a shorter cut off, and less lost travel then equivalent production cylinders. A choice of five bore sizes are available.Īll of AP Racing’s master cylinders have been developed with the benefit of unparalleled experience in racing brake technology, to respond to the severe demands encountered under competition conditions. The cylinder also features a special ‘plug-in’ inlet connection that can be swaged directly to a dash 4 size hose. It again features an aluminium alloy body, and a low profile inlet and outlet. However, the CP6468 is designed to be mounted through a spherical bearing. A choice of eight bore sizes are available.ĪP Racing has also introduced a new ‘pull type’ cylinder is that is similar to AP Racing’s CP6565 type, which has a built-in trunnion mounted in needle roller bearings for direct mounting to the balance bar. It is again suitable for rear for most brake and clutch applications, and is for ABS and high pressure applications. This new compact flange-mounted ‘push type’ master cylinder is of similar design to the CP9093, but features metric hydraulic threads. A choice of eight bore sizes are available. This new compact flange-mounted ‘push type’ master cylinder with centre valve configuration replaces AP Racing’s CP6093 family which is no longer available.įeaturing a forged aluminium alloy body, the cylinder is designed for imperial hydraulic threads and is suitable for use in ABS and high pressure applications, and for most brake and clutch applications. A choice of nine bore sizes are available. This optional feature can be removed by substituting a sleeve for the AKB Plug. The CP6467 also features a patent-pending system that is designed to greatly reduce ‘knock back’. Suitable for most brake and clutch applications, the cylinder also features a special ‘plug-in’ inlet connection that can be swaged directly to a dash 4 size hose. It features an aluminium alloy body and a centre valve configuration which helps to improve cylinder performance and seal durability. This new ‘pull type’ trunnion mounted cylinder is more efficient than conventional type master cylinders and is designed for use in ABS and high pressure applications. This leads to ‘heel nibble’ where the seal is partially extruded up the cut-off port. Seal heel nibble can occur during braking when, in conjunction with ABS, pressure is built up earlier in the seal travel, before it has travelled over the cut-off port. In normal braking operations, seals travel past the cut-off port before high pressure has built up in the system. The centre valve replaces conventional ‘cut off’ ports that can cause ‘seal heel nibble’ when used with some ABS systems. The new cylinder types of CP6467, CP7198 and CP9093 feature a centre valve configuration that helps improve overall cylinder performance as well as seal durability with ABS. AP Racing, the leading manufacturer of performance braking and clutch systems for road and race use, is introducing of new range of centre valve high-efficiency master cylinders.
