Front brake calipers from an '00-'01 RC-51 and the appropriate master cylinder. The calipers bolt directly to the 919's forks, no modifications needed.
The Honda OEM pads still have lots of life left.
$240 + actual shipping. These will fit nicely into a USPS flat rate box.
- not shown in images -- there is a second handlebar cap for the master cylinder that does not have the mirror mount.
