It has no wear to speak of.  It was new when I bought the bike last June.  I went to a 17-tooth in September so I have it to spare.  $20 new.  How about $10 or an un-frayed clutch cable?

That include shipping? I might take it off your hands if it would fit a 2005 model. Most of my trips are an hour long at 65 mph and I'm looking at reducing RPMs to lower vibration. What kind of experiences have you had with the 16t and 17t at reducing vibration and boosting MPGs?

16t is stock unless you or someone else changed yours it should already be 16t
