    No experience of weight limits because I am not the size of a small planetoid.

    KHS owner manual found here -http://khsbicycles.com/PDF/KHS-Owners-Manual.pdf

    Looks like a manual written in the 1980's based on the pictures.

    Bikes do have weight limits. The reason is because they do not have infinite carrying capacity. If you exceed the weight the risks may outweigh the reward. A snapped aluminium tube plunged into your genitals never makes a ride more fun.

    The 1970's called and asked for it's manual back!

    Weight limit is somewhat arbitrary, the forces on the frame are derived from mass x acceleration, so if you ride on relatively smooth trails with no big inputs you wil put less forces into the frame than someone under the arbitrary limit who is using the bike aggressively such as crashing through rock gardens.

    If you have a good look about, manufacturers of rims, tyres, frames etc. have weight limits, they all range around 240-270 lbs.

    Weight or the excess of it has been raised more often on US forums for obvious reasons.

    Just means if the bike collapses and you die, you can't sue them.
    Probably.

    A 10 stone rider can generate greater forces in the frame than a 20 stone rider depending on how they ride. Don't go riding big drops to flat and it will be fine.
    To say there is no safety factor on that weight limit cannot be true, they just don't want to tell you what it is.

    They won't. It's a margin. You are over their stated weight limit so

    Why? As RMSC said, it's a pretty meaningless number anyway.

    The Hardrock is a bicycle for people who don't cycle, mostly fat people who will buy it on cycle to work, put it in the back of the garage and never use it. Putting a 240lb weight limit on a Hardrock would loose half their sells.

    And has nothing to do with the material used, more the intended use.

    i expect that the weight limit has a fair amount to do with clauses in their liability insurance rather than any testing etc that may have been done on the frame.

    I'm kind of missing the point here.
    Company has a weight limit.
    You don't agree with how they put it.
    So what?
    You've been using it for a year. Unlikely to suddenly fall to bits now you know this.

    How is a carbon frame less resistant than a metal one? You're making this stuff up

    My dealer told me this. He said a carbon frame would not handle my weight (275lbs).

    So what? Why does he say that?

    Er no. Carbon could be an inch thick. Actual material has nothing to do with it.

    Carbon frames are much stronger than aluminium frames of the same weight. Most carbon frames are lighter to achieve the same weight but some of the strongest downhill and enduro frames available are carbon.
    Some of the weakest frames are aluminium.
    Strength is about design and construction, not materials.

    TBH I think KHS is right to offer the same weight limit for all their bikes. Actually I think they're wrong to offer a weight limit at all but if they have to I can see their logic in offering the same for every bike.

    It's impossible to offer a safe weight limit for a rider due to the varying riding styles and terrain. For example a friend of mine weighs a little over half what I do but they ride so unsmoothly compared to me they put their frame and other components under more strain meaning they will break sooner with them despite them being so much lighter than me.

    Offering the same weight limit makes sense to me as each bike is designed for a different purpose. A lightweight XC bike may be weaker than a heavy DH bike but the XC bike is also meant for less extreme riding meaning the bike should be put under less strain meaning it shouldn't have to have the same strength as the DH bike to survive the riding it is intended for.

    Why should carbon and aluminium frames be different in strength? For all you know they have been designed to offer exactly the same strength as each other.

    Point is KHS have given you a weight limit. Don't like it sell it and buy a Specialised or something who state a higher limit.
