    Still not recommended for wiping your nose on though. Perhaps there's a little bit more to come out about that story.

    everything relative, sometimes its people luck,

    10 people crash same place same speed same way same type of bike, 9 people will be able to get up and keep going the 10th could damage there frame.

    The idea is to NOT crash, to NOT drop it.....EVER!!!!!
    Frames are replaceable, people are not. End of story.

    Wow.

    Years ago there was an American company that started selling aluminium bicycle frames before anyone else. The side walls of the top tube were awesomely strong lengthwise, but pathetically weak sideways.

    That's because the stress on a bicycle frame is lengthwise, so it made sense to design the side walls that way. Sadly the people who owned the bikes found that even a light bang on at 90 degrees to the tube direction meant a nasty dent.

    It looks like the Gixxer has a similar problem. The frame is designed to be awesome in the front/back and up/down plane, but it isn't meant to be smacked sideways.

    Maybe we are all responsible for this, causing the designers to try to improve the power to weight ratio with every new model. There are only 2 ways to do that, up the power or down the weight.

    Bikes are becoming nigh on flimsy, but able to do warp speed. Just don't do things to them that they weren't designed for (like smacking the frame with the bar end ) and things will be cool.

    Just my thoughts.

    Maybe I think too much.

    Yeah, for the pricetag i think they should be making them so they can be dropped.

    older bikes you can give a preetty hard crash and it doesnt fuss them

    New ones especially GSXR fall apart, im not saying make them indetructable
    ut a 50kph slide shouldnt screw a frame, didnt on old bikes.

    But yeah as you say, it is the power to weight issue.

    I spose it works out to... you crash...it breaks, then you buy another one...

    kaching for suzuki.

    but theres a limit, and condsidering boomers subframe has broken twice just sitting on it (he didn't crash it!) is just ridiculous. (and hes not exactly fat, 80kg or so.)

    they're made to be light and stiff

    they're not made to sustain impacts (binning, landing wheelies, stoppies etc)

    it's called monocoque construction. keeps weight down with good strength in the intended directions.

    aeroplanes are built the same -super lightweight materials put together in such a way that the sum of the parts are super strong. easy to punch a hole in the side of a plane though.

    Bro, should clarify it's your rear most subframe subframe if you like. Only holds the plastic bit on the back. HTFU

    ummn, Monocoque construction essentually means stressed skin. EG, airplanes, jap cars etc etc.

    n.

    A metal structure, such as an aircraft, in which the skin absorbs all or most of the stresses to which the body is subjected.

    [French : mono-, mono- + coque, shell (from Old French, from Latin coccum, berry, from Greek kokkos).]
    I fail at seeing how the subframe of any bike could be stressed skin?

    -------------------

    why are people not designing/building/selling/modifying their subframes to remove the failure points? I have no idea where these frames are cracking/breaking but it surely cant be too hard (and will be relatively cheap) to get a few additional gussets welded in.

    You my or may not be taking the piss
    but its true

    I mean hell 170hp at the wheel (being generous) is going to stand up pretty bloodey easy.

    And the brakes they have will stoppie them.

    Its not like suzuki dont know people stunt gsxr's if they didnt want to do wheelies etc they dont have much need for a 1000cc most of the time.

    unless on the track...

    They should be made stronger.

    from suzuki:

    Aluminum alloy twin-spar frame is built using five castings for lightweight, unmatched handling and performance, increased production precision, and reduced weight.

    from kawasaki:

    - Well-balanced aluminum monocoque frame provides superb stability and reflexive handling

    could argue semantics i guess.
