Stephen, how many miles do you have on the '12 Vee? In testing we have seen the early signs of chudder at just over 3,000 miles. Not to the point where it is objectionable, just that after knowing what it is you can tell it is there. Do the chudder test: while riding thru the range where you feel the vibrations lightly feather the clutch lever. Just put a bit of pressure on it, not enough that the clutch slips. You are "loading' the pressure plate which stabilizes the basket. IF that makes it smoother you have chudder to some degree at least. The clutch basket on the 2012 Vee is the same as the early models, same part number so there are no improvements. While it is possible you might get the dealer/suzuki to replace your basket under warranty, it is not a "permanent" fix. My WERKS basket is actually smoother than a new basket and is meant to be a long term fix for chudder issues. If you want more information about that contact me at info@werksparts.com Terry
