This site caters for a variety of
bikes including Kawasaki, BMW and Harley-Davidson. Based in California,
this manufacturer makes seats to order and guarantees that no
two seats are the same.
My personal favourite is Corbin at www.corbin.com
Don't underestimate the importance of a comfortable seat. I bought a Corbin seat for my first GTR and moved it from bike to bike - expensive but one of the best investments I made.
An added bonus of the Corbin seat is that it provides a great backrest for the pillion offering a much more secure ride for them.
