Yep. I've tracked every bike I've owned since starting riding in 2010. 2 DCTC (DCTC is a small road course 1 mile long w/17 turns) ARCs on the '09 Ninja 250R, 1 DCTC ARC and a trackschool @ BIR on the '08 GSX-R600, and 1 DCTC ARC on the '08 848.
DCTC on the G6 after about 600 miles experience on it:
ZARS Trackschool 1 @ BIR (~1000 miles of seat time on the bike prior)
DCTC on the near-stock 848 after I had it for a week.....not confidence-inspiring at all....as I was already accustomed to how an I4 600 felt on track. :-/
For the 2012 season I kick off by going to Infineon Raceway in CA in a month for Levels 1 & 2 of California Superbike School (using their BMW S1000RR) on April 2 & 3, then a trackday at Road America in WI at the end of May, Jason Pridmore STAR School at NOLA Motorsports Park in New Orleans on June 4, possibly a BIR (Brainerd Int'l Raceway) trackday on June 9, back-to-back trackdays @ BIR on July 21-22, and the final trackday @ BIR on Sep 3.
Hope to make some real progress this season on the new-to-me bike....both in confidence and skill level.
