I have the Solo with the Ostrich and the backrest. Absolutely love it. For me, it was comfortable on day one. Great customer service and the seat still looks perfect 3 years later. I get a lot of compliments. I'll post a picture later.
Agree with the above. Great customer service! Very happy with mine as well.
Not Ostrich, I went with Aligator insert and matching bag lids. They will send you samples also.
Good luck!
I've had one on every bike I've owned. Did a 1,300 mile roundtrip ride last year and my azz, or lack thereof, was fine. I have a C&C Solo w/ pillion, but probably will sell it so I can get a C&C two up seat.
