Posting here since that's where the Dyna Ring discussions seem to occur. When someone else posted about the recent availability of 450 units, I went to the revloc site and asked: I just saw the announcement on Cafe Husky that the 2008-2010 450/510 Revloc unit is now available. I have been waiting patiently for a Dyna Ring for my 2009 TXC250. Do you have an ETA (or a decision not to produce) for the 2008-2009 Husqvarna TE/TXC 250 models? I got a quick answer: Sorry to let you down , we are not able to produce that particular year and model. We have run into space issues on that clutch and the supply demand issue is another. We are working on the 2011 tc/te 310 clutch currently and that is looking very promising for what its worth. Thank you for the e-mail and maybe a trade in for the 11' is in your future? Revloc Sales Not the answer I wanted, but I can stop waiting.
