Lovely bike, Plenty of engine braking, I just bought my first inline 4 last week. (yamaha R1) and still cant get used to how little engine braking there is!
The instructors don't charge a thing to follow you for a session, and they helped my confidence massively,
There will be a couple of briefings before your first session, that is proberly the best time to ask them.
You will have great fun, and they really are great guys.. Just remember though, you have to ride the bike back home at the end of the day.
Oh,
On your first session the instructors will lead you all for 2 laps, so try to be at the front to get to see the lines.
