Well, that's about it. I went to the local race track which is very small....best times are held by 125cc GP bikes. But you can still get over 80 miles an hour on it...Anyway it was a practice day. And the 1000s and the 600s were riding together. The 1000s went coasting by sounding like cars...and the 600s sounded like...well...awesome. Yeah...I know a 1000 would sound great once you got the RPMs up...but even in first gear you need to be doing 60 miles an hour...and you've still got another 30miles/hr to go before redline.
