We only have one saddle - PM your address and I can send you a sample. However, the Sport R500's are only being released in matte black vinyl w/ 5 variations for stripe/stitching color: White, Red, Gray, Black, and Blue.
Sorry no - the stripes are not optional, they are part of the pattern. However you could opt to get the stripes the same black vinyl as the seats and they would blend in.
We can do custom colors and combinations - but there will be an up charge for the custom colors on these seats.
