    Anyone try a 6 pot brake conversion?

    I'm looking into the feasibility of updating the brakes on my '83 1100E using 6 pot calipers. I haven't bought anything, yet.
    I'd like to know if anyone else has tried this. If so, please post the lessons you learned or PM me so I can get some advice.
    Thanks,
    Willie

    I've heard less than stellar things about 6 pot calipers. The general consensus seems to be that 4 pots are the best overall.

      Never used them so take this for what it is worth (which is nothing), talking to guys who worked at buell years ago I was looking to go to 6 pot on my 1150 and was told by them that unless I had a larger brake rotor going to a 6 pot would not work as well. They were convinced the size of the rotor was way more important than the caliper. Of corse buell pushed that design to the limit.

        Interesting. Any one else want to add their opinion or findings?
        Thanks a lot.

          I have 6 piston calipers on my bike way better than original 1 piston but I am told the 4s are better. Something about the pad is too long on the 6

            You get greater swept area with 6 piston calipers but they are said to flex a bit due to the length of them. 4 piston calipers for street use will be more than adequate and light years ahead of the single piston stcokers you have. You are going with floating rotors I hope.

              I did the twin pot conversion on my last 1100G and was happy with the results. I was just looking for something better, if possible, this time around. I am/will be using floating CBR rotors. Thanks for your concern.

                I'm not an expert but I believe the problem with mounting opposing piston calipers on a stock GS fork is there isn't enough room and the caliper will hit the wheel spokes.

                  That is part of the problem.

                    6 Pot is really not that great... That's why Suzuki upgraded the gen 1 Hayabusa brakes from 6 pot to 4 pot when the Gen 2 came out... Get twin pot, it's more than adequate. Not to mention the general consensus is 6 pot brakes are a pain to bleed.

                      Exactly correct. Caliper/piston layout details do matter some, but rotor diameter (or more correctly, rotor/tire diameter ratio) is way more critical.

                      The biggest braking improvement I've ever made, on any bike, was when I changed the front rim on a mini motard bike from a 19" to a 16". Didn't touch the brakes themselves, but the increased leverage that the brakes had on the contact patch made a world of difference. Enough that I locked up the front wheel and crashed going into turn 1, on my out lap. (In my defense, it was 38? and raining. )
