I've recorded a 1'09.691 lap time around the Midfield circuit riding a Yamaha YZF R-1 (RM). Bit of a story behind my lap time, I decided to try to bring my lap time up for the R-6 (RM) which at the time was the slowest 600cc bike for me. I setup the R-6 and blitzed my fastest lap time by half a second. I then rode the R-1 (ironically it was my 1st time on it) and recorded my 1st sub 1'10 time.
Unfortunately due to my disability, I'm unable to use manual gears I had to use an automatic transmission instead so the time set is probably down to that factor than any other. I set the time in the Time Trial mode.
