Don't forget the new KYB suspension on the 16s as well. Yamaha is dumping remaining stock on the 15s because they have extras. I heard from my deal that there's at least a $1200 rebate on them. 16s are now becoming rarer as the 17s take over. The 'new' KYB suspension has been there since 2012 There have build prodution build changes, but the suspension is the same. Which is good.
