I am both a motorcyclist (Ducati 999) and cyclist. My tolerance for relatively high speeds is...high. 90% of the time the moto's give plenty of room and all is fine. The 10% of the time they don't it is because they are riding far too fast for the conditions and generally their abilities. Take it to the f'ing track - that is why it is there. Anyplace in LA or the Bay Area you are a few hours from multiple racetracks where for $100 you can ride all day as fast as you want/can.
