Yeah - they're REDICULOUSLY expensive?!?!
I bought a thunder grey one with my 2010 RR.
For those of you who WANT a solo cowl and are SMART enough to NOT be willing to pay almost $500 by the time all the brackets/locks/etc. are installed, i ran across an alternative on eBay last month:
S1000RR Carbon Seat Cover
$208 is an
AWESOME deal - considering it's a real CF piece.
As I have NOT bought one, I am not sure about the quality, but I sure wish THIS option existed when I got my cowl!
