This is Rossi here speaking. I've done two trackdays this summer. Now I drive my bike like the guys does in Fast and the Furious movies...Nice nature but not curvy roads are boring...
Seems like you were trying to respect the speed limits... there is no other reason in my mind that you were riding so slow... in these roads its easy to keep speeding at 180-200km, easily for someone who trust his riding skills.
If i was you i would starting learn how to ride properly in a "riding school" (like California etc).
It's not a negative comment, just an advice to another rider to be more happy!
