Look at the numbers: 857 bicycle deaths[1] vs 4985 bikers[2]. You can look at the unit sales to see how those translate to percentages - but I hope it's easy to agree that there are more cyclists, in fact.
Your theory that motorcycle max speed saves lives is simply unsupported by any data; if you can't see it, it's just cognitive dissonance - you've made up your mind that you like loud speedy bikes and are just looking for justifications.
(don't get me wrong - I fully understand that a slow motorcycle is no fun. But it _is_ a dangerous vehicle - own that, don't use loud noises and other means that inconvenience people around in order to feel slightly safer, that's just inconsiderate. )
