faussy Posted November 7, 2016 Report Share Posted November 7, 2016 (edited) Dad of 2 you don't half talk some poo!The colour of the break is fine light grey,yes as its steel!The size of the mounting on non std footrests can cause stress?Yes if the bolts dont fit and are loose?Aftermarket footrests are less flexible?WTF they are about ten cms long i doubt if they flex at all!The only thing stressing the frame on my bike is my 15 stone carcass and bouncing it off some large rocks! Totally disagree. The standard pegs do bend or crush if you hit a rock hard. Billet aluminium or titanium pegs do not bend. Seen many a frame bend or hanger break, when a standard footrest would have just bent back. Edited November 7, 2016 by faussy Quote Link to comment Share on other sites More sharing options...
andrewmorpeth Posted November 12, 2016 Report Share Posted November 12, 2016 Mine were standard and I've only had trouble when colliding with rocks.If you mean that aftermarket ones ,badly fitted with no common sense used,will bend the mountings yes.But any flex in the footrest would be so small as to be insignificant!But hey I bow to your superior knowledge in all things as usual you know better than anyone else with a degree!

suzuki250 Posted November 12, 2016 Report Share Posted November 12, 2016 Before slanging someone off perhaps you should look up the difference between brittle and ductile fractures. Many aftermarket footrests are narrower along the bolt axis than standard footrests. People then nip the bolt up to remove slack stressing the mounts in a way the designer did not intend. Loop type footrests flex quite a lut back to front cushioning the force transmitted to the frame. Stronger aftermarket footrests flex much less and more force is transmitted to the mount / frame. The brake in the photos is almost certainly due to brittleness and an impact trying to push the footrest forwards, not rider weight. I work in engineering , and qualified to say 'sh!t happens'. That’s why machine mart sells welders 3 Quote Link to comment Share on other sites More sharing options...

Standard footrests DEFINITELY flex!!!! Ive a box full of old ones bent out of shape. You are welcome to come look at them. Ive yet to see a set of billet aluminium or titanium footrests bend Edited November 14, 2016 by faussy 1 Quote Link to comment Share on other sites More sharing options...
crazybond700 Posted December 11, 2016 Report Share Posted December 11, 2016 (edited) Saw this before a almost brand new bike. Quite sure it also was a 014, with non-standard foodpegs (maybe standard for that particular model, but not the standard type) Edited December 11, 2016 by crazybond700 Quote Link to comment Share on other sites More sharing options...
steve_earle Posted December 17, 2016 Report Share Posted December 17, 2016 Aftermarket foot pegs, especially the ones with the adjustable spacers put all the stress at the end of the mount. Std foot pegs tend to fit the shape of the mount more so when you whack one the force is more evenly distributed over the whole mount rather than 2 small contact points of the spacers on aftermarkets. Also adjustable foot pegs or more rearward spaced ones can put slightly greater stress on the mount due to extra leverage or the angle of force applied to the bracket.

guys Posted December 17, 2016 Report Share Posted December 17, 2016 It doesn't matter much if the foot pegs have a little bit more play in the bracket. Because in either case the most force is transferred through the bolt / pivot which connects both, because there's always play between the bracket and the foot peg.
