I don't know the answer to your question, but I do know that you should NOT get them from Lockhart Phillips.
I know, that should be common knowledge, but I bought a pair of blue anodized levers from somebody on the board who purchased them but never installed them. I put them on last weekend, and the VERY FIRST time I test-loaded the front brake lever, it absolutely shattered at the pivot. Little lever bits went shooting across my garage floor, and I didn't pull it very hard at all. Thankfully, the bike was on a stand in a garage and not behind a semi on the highway. Naturally, the clutch lever came right back off, and the old silver stubbies went back on.
I suppose Lockhart Phillips is like the Radioshack of the motorcycle world ... don't ever buy anything critical there.
the blue ones I have I think are LP... I do agree LP stuff tends to be lacking in quality most of the time but these levers haven't given me any trouble so far. I have had some C/F models too and I have found that none of the aftermarket levers seem to built as good as OEM except maybe the roll-a-clicks which are outrageous in price
whatever you get, really make sure to lube the pivot point. any lever you get could easily snap if you don't. i agree, the lockharts aren't great but i've had several and had no problems, nor has anyone i know until now. it couldn't hurt to find a better brand though, just in case.
