My older brother lives in San Francisco and rides a green Yamaha R-1 (170hp, 0-60 in 3.5sec if you can hang on) which he has named "Green Destiny"...he ditches cops all the time in Berkeley,CA. He always rides fast...so when he get's caught in the city he normally just keeps on speeding and makes a few turns to loose the cop.
Cops turns lights on...brother hits the gas makes a turn, does 0-60 again in 3.5 seconds, makes a turn and 0-60's, makes a turn then find's a nice spot for a shot of espresso.
Says he done it by himself and with a friend about four or five times in total...all in Berkeley, CA. If you know Berkeley at all, you know the streets are perfect for loosing squad cars if your on a bike...traffics not too heavy, a lot of short streets with a lot of stop signs...it is apparently easy to loose cops in about 2-3 turns in these conditions.
However, when my brother gets caught on a highway he pulls over because there is no where to run.

And yes...my brother is proud of it and in all other respects an upstanding citzen. In all of his years of riding he been pulled over at least ten times but has only received two tickets; usually the chp start asking him about his nice bike or his height (my brother is 6'7"

or something.
One his friends, whom I also know, almost got caught doing this...when the cop flashed him from about 100 feet back he did the turn and burn number like I said above...he then pulled over at a McDonald's to get some food. About 10 minutes later the cops saw his bike and stopped and started questioning/harassing him. However, this was before all squad cars had camera's in the cars recording all the action so the cops had no proof that he was the guy who ditched them...since he had been parked at MAC's for about 10 minutes some of the people there were defending my brother's friend. The cops were trying to get him to confess saying they'd just give him a ticket and impound his bike but not arrest him. My bro's friend held out to the end so the cops had to let him go... as far as I know, he still speeds like a maniac to this day.
