939sp

Hope everyone had a safe and fun weekend. I was very lucky and got to ride the Tail of the Dragon over the weekend on a work trip so that was fun! So just a quick background on myself I am currently a test engineer for an automotive company called Local Motors we are currently in production...

A new 950SP is about $20k all in cost, I can pick up a 939SP with 2k miles for $10500. I know Ducati made a lot of changes for the new bike but its essentially the same engine but with a different torque curve and an extra 4hp. Is the new bike worth the extra S10k? Anyone ridden both?
