Yamaha part number 56a-26372-01 it is a front brake master cylinder lever rubber guard fits late 80's IT, YZ and such. One of those parts I have a tendency to pop in my cart when on motorsport.com to reach free shipping had it in my extras box.
Fit quite nicely, well retained, very good coverage, opening to the rear larger than is necessary, but frontal coverage for keeping roost and dust and what not off my nicely lubed lever pivots is excellent, interference with normal operation is 0, fit/finish very nice, little pocket for the bolt head lines up perfectly with the bottom nut, nothing to hold up top by design of the countersunk allen head, but the rubber block snaps up tightly over the bolt head where you adjust your lever/bar distance and it is not going anywhere.
Something to consider if you are shopping somewhere that sells OE parts and need a little extra.
