Hey Tony,
I must claim ignorance on the exact brand of the bikini. I have the receipt from the first owner but I cannot make out a brand; it does fit well though!
The stock airbox was relieved of some of it's "roof" which allows it to breath better and still clamp down on the BMC 104 filter in it.
Also forgot to list on the initial post that the bike has a vizi-tec brake light flasher.
