Brembo OE 85-95 BMW R65 RT 650cc 285x5mm Brake Disc - Front Floating

What you get here is a Brembo OE Powersports front floating brake disc, part number 78B40892. This disc is built to be a direct replacement for your original equipment, meaning it's made to fit right onto your BMW motorcycle without any fuss. It's designed for a range of BMW models, including bikes like the R100GS, R80/7, and R80RT, ensuring you get a solid braking upgrade.

This disc features a stainless steel braking band that's connected to a CNC-machined, anodized aluminum alloy hub. The connection uses precision drive pawls, which allow for controlled movement and expansion while keeping tight tolerances. This construction helps with superior braking torque transfer and makes the disc more durable under heat and stress. The specially placed hole pattern on the disc is there to help with heat dissipation, keeping your brakes working effectively even during hard use.

Brembo has been in the racing world since the mid-70s, and the Serie Oro line, which this disc is part of, was their entry into that arena. They've used that experience to engineer optimal geometries and tolerances for a wide variety of riding conditions. This disc is built to meet or exceed original equipment standards, giving you confidence in its performance and longevity.
