tomch Posted September 7, 2013 Share Posted September 7, 2013 I leapt off a 1 foot bank and both the dog bone pivots (back suspension linkage) have exploded, collapsing the swingarm onto the exhaust pipe. When I have recovered my bike I shall photograph it... Quote Link to comment Share on other sites More sharing options...
zippy Posted September 7, 2013 Share Posted September 7, 2013 Any damage to the exhaust? seems odd that the dog bones would fail like that. have there been any BIG hits or drop offs before this? or is it a faulty set of dog bones? Quote Link to comment Share on other sites More sharing options...

dadof2 Posted September 7, 2013 Share Posted September 7, 2013 Yep, common problem Quote Link to comment Share on other sites More sharing options...
canada280i Posted September 7, 2013 Share Posted September 7, 2013 Never seen or heard of it before on any of the 20 or so ossas I know of in my area, ism interested to see what is meant by exploded, did the bones themselves fail or was it a failure of the dogbone pin? I know they modified the pin on the 2013 models Quote Link to comment Share on other sites More sharing options...
tomch Posted September 8, 2013 Author Share Posted September 8, 2013 The fractured pieces of the front of the dogbone. Quote Link to comment Share on other sites More sharing options...
tomch Posted September 8, 2013 Author Share Posted September 8, 2013 The pivot pin seems undamaged and straight... Hard to photograph Quote Link to comment Share on other sites More sharing options...

tomch Posted September 8, 2013 Author Share Posted September 8, 2013 (edited) The back pivot broke on one side too..... The drop off was tiny and I'm not an aggressive rider (ask anyone who saw me in action at the SSDT this year) though I do weigh 95kg. It looks to me like a failure of the casting... The exhaust pipe is dinkled in at the bottom, forcing it off the engine port. I shall probably need a new exhaust pipe it will be impossible to straighten gas tight.

canada280i Posted September 8, 2013 Share Posted September 8, 2013 Yes bad failure, are you still in the warranty period? On another note, it does look very dry around the pivot points in there which could have had an impact I suppose Quote Link to comment Share on other sites More sharing options...

jsp Posted September 9, 2013 Share Posted September 9, 2013 My 2012 did the same, Birkets sent me a full 2013 rear suspension set up under warranty which is a lot stronger and uses bolts rather than C clips Quote Link to comment Share on other sites More sharing options...
canada280i Posted September 12, 2013 Share Posted September 12, 2013 did you get the dogbone fixed under warranty? Quote Link to comment Share on other sites More sharing options...
tomch Posted September 13, 2013 Author Share Posted September 13, 2013 No luck, have to buy all the parts which will take ages.... Quote Link to comment Share on other sites More sharing options...
