Ahhh the power of Google... bst's are carbon fiber wheels - I should have known.

I ride all the time on all of my superbikes with my wife, I just make sure the suspension preloads are ready for it - it's not like your racing on the street - when you think of what these superbikes are capable of compared to what we put them through on the street - a passenger is nothing. There are even schools and charity events that have GSXR's set up for 2-up lightning laps... Chris Ulrich, Randy Mamola, Cornerspeed Braking Demonstrations, YCRS, the list goes on.
I personally in my ignorance would have no problem at all adding a passenger to C-F wheels, but I would have a problem hitting big potholes... that should go for any wheel though.

BST's on my 996 have not had any issues with passengers. I'm 165 and my son on his last ride was fast approaching 150, with gear we had an additional 40-50 lbs. My daughter doesn;t really count, she is just over a buck with gear on, but they have had numerous rides with me for more than just a few miles.

Biposto set-up is the factor, proper rear subframe etc should have you covered.

Time and time again it has been proven that the BST carbon wheels are STRONGER than most other wheels, be them steel, aluminum or magnesium! I can understand how/why people have reservations about a wheel made of carbon fiber, but if these wheels have no problem handling a turbo charged 300+ hp Busa launching on a 8" slick rear tire, i doubt you can find a girl big enough that these wheels would flinch at. Hell, id venture to say your going to break the rear subframe before a BST. That being said, GET THEM!!! I have them on my 999s and love every second of it, potholes in the street and all.

BSTs have been on my ST4S for more than 25,000 miles - never an issue. I've never had a passenger on the bike whilst they have been on. However, I'm about 220 with my gear, and the bike is usually fully loaded for touring. The bike has also been down a few roads with less than perfect pavement.

Best money I have put into the bikes.
