Who has has tested or uses front radial braking pump/levers ?

why? for looks? to be "pukka" ??
normally, you'd fit the 19x20 or 19x18 radial pump to a bike with double front rotors. the 16 may work. ... but the 16 is billet and about 2x the price of the forged 19. the only reason i'd bother to do this is to go with a single rotor and the billet 16 radial pump.
note that there is no provisions for brake light switch or reservoir mounting with the brembo radial pumps.

Hey Chris - Those BrakeTech Rotors and Ferodo CP911 pads you hooked me up with are THE BOMB! I had my rear wheel in the air using one finger coming off the back straight of Pocono yesterday. I really had to lock onto the tank to keep my weight shifted back, or the rear end would go all BBoz on me and swim all over.... Sweet kit. They sell those bits here on the Forum, as well.

The Brembo, AP and Magura radial pumps are awesome. They make the feel much more linear and lower effort....or higher if you use a different setting on the Magura or AP. I would also use the larger diameter piston assembly for the RS250.

I have been using the braketech cast iron full-floaters featured on the "shop online " site for a year now...incredible! Much more feel that the stock rotors! I have a APracing master (radial) on my ducati, and it is terrific, but I think it would be overkill on the APrilia 250. I personally love the stock mastercylinder on the Aprilia 250 Challenge series bikes!

yeah, the master cylinder on our bikes is the same as on other full size aprilias and ducati 900SSs and 916s, only not gold. it's got a goodly bit of power behind it.
i think a single 320 rotor and the 16mm radial pump would be THE hot ticket, where allowed by the rules. if i can get some spare time, i'll machine up a couple adaptor plates to space out the caliper to the 320 size. then, you figure a 4 pad "bridged" brembo caliper, the Brake Tech ductile iron rotor (with cryo treatment), and the Ferodo XR racing pads? i'd be surprised if the stock setup was stronger than all that. and figure that's at least 4 pounds shed from the front wheel...
