Hey guys, so I'm buying ohlins 25mm carts w/ stock forks and ttx rear that apparently came off Josh Herrin's old bike and went onto a 2008 R6, going onto my 2012 R6, for $1750 and only been used roughly 3 races since it's last service. Finalized the deal but haven't purchased yet, does this sound like a good deal? Or for the extra $500ish bucks worth it for a brand new set?
