2011 Metzeler Interact Challenge at Cartagena

I've spent all day testing Metzeler's K3 Racetec, M5 Sportec and Z8 Roadtec tyres. I've done that by doing my first session on the 2011 Kawasaki ZX-10R, second session on the 2011 Suzuki GSX-R600, third session on the 2011 Triumph Daytona 675R and the final session on the 2011 BMW S 1000 RR splitting the session between the K3 Racetec and M5 Sportec tyres on the S1KRR. Following that we headed out onto the roads where I spent half the time on the 2011 Kawasaki Z1000SX and the rest on the 2011 Triumph Speed Triple. Needless to say it was a fun day but also very intensive with so much testing crammed into only one day. I've got onboard video of all bikes apart from the S 1000 RR when I had to save some space on my SD card for the roadtest. The Suzuki GSX-R600 onboard video is great with good sound and all but the most exciting is probably the Kawasaki Z1000SX onboard videos.
