A safety recall issued by the NHTSA in the US covers Brembo front brake master cylinders and covers certain Aprilia and Ducati motorcycles. The safety concern is with regards to the front brake master cylinder piston, which is made of plastic and may crack after hard use.

Models currently affected by the recall are the 2017 Aprilia RSV4 model range and the 2017 Aprilia Tuono 1100. Ducati models also fall under this recall, and the affected 2015 to 2018 model years are the 1299 Panigale, Panigale R, Monster 1200, Multistrada 1200 and 1260, XDiavel S and Scrambler 800 Cafe Racer.

The specific Brembo brake master cylinder in question is the PR16 model, often used in conjunction with Brembo M50 callipers. Problems arise when the master cylinder, made from a plastic called polyphenylene sulphide may crack after hard use, such as racing, or when the motorcycle’s ABS is activated too frequently.

Remedy for the this recall in the US is replacement of the plastic master cylinder piston with an aluminium unit. This replacement will be done at the respective brands’ authorised dealer and will be performed free-of-charge in the US beginning February 15.

Application for the Brembo PR16 master cylinder is wide, and covers a multitude of top-end motorcycles, including other manufacturers such as KTM, Kawasaki, Triumph and others. Aprilia and Ducati owners may contact the relevant Malaysian distributor to find out if their particular machine is affected, while aftermarket users of the PR16 master cylinder are advised to contact Brembo directly.
