My wife hated riding on the back. She wanted her own, so she got a Suzuki C50. She doesn't ride as much as she could, but she does ride hard when we travel.
well, being that she is only 4'6" tall we had to find a bike to fit her and it is a Yamaha Virago 1100.
I have been asked many time lately if I have a problem with her riding -- and I have to say that I am concerned when she rides, but she knows how to ride and is an excellant rider --
Wife's first was a 99 Sporty, then a 07 1200L, and now 08 Heritage. She just took her first long trip to the 105th, she done awesome. I'm real proud of her and as others have said I alway worry, but she keeps right up with me.
