Honda CBX1000 Front M/C Brake Reservoir Seal. Replacement front master cylinder brake reservoir seal made from EDPM suitable for all DOT brake fluids.
We use these seals on a regular basis on our brake rebuilds on recommissioned bikes and are as good quality as the original at half the price.
This fits many other Honda motorcycles including the early CB DOHC and CB250/400 Superdream.
