The rider in front has the right of way. You shouldn't be worrying about what is going on behind you. Not to mention you should easily be able to hear if a bike is close.Why the hell, motorcycles are not allowed to use their mirrors while on the racetrack?
Cars do keep all their mirrors.
If cars can see whats going on behind them, why not bikes? ha?
Why? why? why?
Loud Pipes Save Lives.On a motorcycle, you're moving all over the place, so mirrors would only be useful on the straight and if there is someone behind you, you'd hear'em.
