BIKES...?!?! CRIKEY...I'm an ex-roadracer meself...!! I raced production based 600's for nearly 10 years. WE raced at our home track at Gimli Manitoba(look it up under MRA, Manitoba), and also at Brainerd Minnesota in the U.S.
I raced with a Kawasaki sponsorship for nearly 5 seasons, then switched to Suzuki on a 2 stroke, 4 cyl. Gamma. That thing was a Sidewinder on 2 wheels...!! It had bugger all downstairs, but when you hit 6k rpm...BAM...hold on for dear life...!! The power band was like a light switch...ALL or NOTHIN...and I'll never forget goin into turn 1 at BIR and takin a peek at the speedo, somethin you should NOT have time for, and seeing the needle comin up on 150...!!!!!! Having crashed BIG TIME the year before(hitting the underside of the pedestrian bridge in turn 9 and destoying my GPZ 550), I was a little wobbly kneed when I finished tearing thru turn one as I made my way thru the other turns comin up on 9.
I was wondering if I would have any flashbacks to the previous year's crash around the same time of year, but as I approached turn 9...NOTHIN...not even a micro-flash of the incident. Oh, well I thought, lets go RACIN...!!!
After I retired from racing full time, I refereed races for 4-5 more years, doin tech inspection for the WSBK's at Mosport for a couple years. THAT was a treat seeing the factory machines and meetin riders like Fred Merkel, Raymond Roche, Doug Polen, Carl Fogarty...to name a few. Ahhhh those were GREAT times to be sure...the smaell of Castor oil in the morning...
Later mate, I have many more stories if you care to read...I'm such a blab when I get goin...!
