I rode my 2007 S2R1000 yesterday with stock ECU and stock exhaust on it. It was fun, and powerful, and I had a blast.
Today, I jumped on my 2008 S2R1000 with Ducati Performance ECU and full Zard system on it. Holy Cow!
The difference in power was surprising, even when I expected it to be noticeable. And the Roar! The noise coming off that thing was so fun!
Anyways, just wanted to share.
