am i the only person that is going to tell you no?
aftermarket rims are pure bling,
and yes they are lighter then stock OEM rims, but be honest to yourself, can you even handle the stock power of a r1? yea that slip on... noise and bling, same thing for rims, its bling
i got marchesini rims on my 09, if it was my $$$, id buy a season pass to a local trackday provider, and hand the leftovers $$$ to the pirelli tire guy - this way the $$$ is actually being spent wisely, and i get to keep on expanding my skillset and continue to learn new things
having aftermarket rims - makes you clean your rims like a crackhead after each ride, and makes you extremely frustrated/mad when you see rock chips on them.... i am thinking about selling my marchesini to pay for trackdays next year
