    Broken Throttle Body Pulleys 2009 R1200RT

    Has anyone every seen this happen? Mine broke on Wednesday. I was shifting to second and the RPMs dropped to idle. I had to get a tow and after I got everything off, I eventually discovered the pulleys/cams on the throttle bodies were broken off. They are plastic, which is incredible. Is the bike made by Mattel? Steel has always worked...

    I think this very issue has been discussed a couple of times on the threads. I'm curious if the '05's were steel, as I don't here much about their failure.

    BMW NA suggested I have it fixed at a dealer. Whatever. I know what's wrong with it and new parts and labor would probably cost $1400ish. May be a little more. Using plastic is ridiculous.

    So what was the verdict? You gonna order the part and replace it yourself. Does BMW offer a non-plastic throttle body pulley?

    I found a set of throttle bodies on ebay with the cables/cable distributor box/fuel injection. The pulleys cannot be replaced by themselves. THe whole throttle body has to be replaced.

    The pulley on each throttle body broke simultaneously?

    That is just bizarre.

    Good for you Ponch.

    Hopefully BMW NA will step up to fix this significant safety issue. There is hope, especially since they recently started replacing left and right switch gear on the 2010 and up models, even those not experiencing a failure. I don't believe, the switches were nearly the level of concern as this piece.

    Hope you get back on the road soon.

    Aloha

    There is no such thing as bad plastic. There is a lot of incorrect application of plastic. The interface of plastic over metal is a hard one to do correctly.

    I can not believe the weight savings was significant.

    Not sure what you mean by plastic over metal, but the pulley is separate from the metal parts and doesn't have metal within it. That said, I was jesting when I said save weight. May be sarcastic is a better word.

    Unless I am lost somewhere the pulley is plastic; the shaft is metal.

    I think this is a golden opportunity for a bright engineer / entrepeneur with a 3-D printer.

    It would be great if an engineer amongst us would assist to develop a retrofit using a more appropriate material. I am sure anyone in Ponch's situation would gladly compensate the individual should they need help.
