I dunno -- there are a lot of riders with big feet (make of that what you will...) desperately searching for boots. If he can figure out what size they really are, they'll sell instantly.
If BB's automated systems work as designed (which they do most of the time), they're great. But if there's a problem or if you have a question, they're terrible to spotty at best.
Last time I called BB, I got a terrible echoing VOIP connection and a polite gentleman with a Hindi accent named "Victor". (Yeah right...

) -- all hallmarks that a company has officially jumped the shark and outsourced support to India. "Victor" was cheerful and polite, but completely unable to deviate from his script or do anything at all useful for me.
However, the next time I had a problem with an incorrect part (Suzuki packaged the part wrong, so it wasn't entirely their fault), I used their online chat function. To my astonishment, within five minutes, the problem was solved, and three days later I had the correct part in hand.
I haven't ordered Suzuki parts from BB for quite a while, although I've taken advantage of a couple of gear clearance sales in the last year or so.
For Suzuki parts, I order online through a couple of local dealers, either Flat Out motorcycles or Westfield Yamaha Suzuki. Westfield doesn't charge shipping on orders I pick up in person, and their prices are nearly identical to Flat Out, so I've been using them lately:

It's really nice to stand there at the counter and go through my order to make sure it's correct right there in the store where there's a human being to take care of any problems.
For gear, it's
http://newenough most of the time, and also
http://www.motorcyclecloseouts.com/ . Both have great deals and excellent service.
BB is convenient when you need parts for other brands -- they have online fiches for everything from Harley to KTM. Just don't get in a hurry or in a position where you NEED that part before you go. As they clearly warn, don't disassemble your vehicle or render it inoperative until you verify that you received the correct part...
