Well I got my corbin seat today and what a disaster it was at first... None of the mounting brackets matched up with my RR... I called them and they really didnt believe me.. I ended up having to take pics and email Corbin the pics for them to even think about taking it back... And they said they mold them from the bike.. Bullsh!!... The mounting holes weren't even level.. and about 1/4inch off... The rear seat had no chance of fitting.. Why would u mold a rear seat of a 600RR, when my bike is a 1000RR.. No refunds they said.. Have to send back and wait 4 weeks while they check the fit themselves.. Not very impressed with Corbin..
