Harley guys don't have a valid reference point for what fast is. Why bother with them? Kind of like being able to out run a guy with one leg, when you have two. Where's the glory and thrill in that? What's to be gained? Bragging rights? I'm faster than a Harley.
Keep the Ego in check it will get you in trouble more often than not. It's a dangerous thing on two wheels. Riding fast is one thing, racing stop light to stop light in order to prove something is another . Remember, what ever happens to the other guy or anyone else in that situation is going to get blamed on you regardless if you were at fault or not. You can't control what he does, but you'll pay the price for it just the same.
Just sayin'. Something to think about next time someone gives ya a rev at a stop light.
Tell 'em nice bike bro and let 'em disappear.
Besides you can't really win unless there's some predesignated finish line anyway.
