I went to a motorcycle rally yesterday and they had one of the mobile dyno drag strip. I seen several of these before but never ran on one. While I was in line there was a guy that had a Cbr 1000 that set the new low for the event at 9.4 at 168. I was next up and I set the new low with a 9.05 at 149. My next pass I rest the low et with a 8.87 at 153. I know these things are off cause my bike runs 11.50s at the track. The guy told me it just takes your horsepower and torque and figures it at a bike and rider weighing 425 lbs. So for all your buddies that have had there bike on one and tell you that it's a 9 second bike it really probably is a 12 or 13 second bike. Knowing it was off but it is just reading power and torque numbers I'm still pretty happy to come away with the event low et.
