Lets see...if you have ever owned an Ultimate, there is nothing else to say..... First class, all the way!!! Very,Very comfortable, Driver back rest is Perfect....fit and finish...Perfect!!!! Can be delivered in about 3 weeks... The regular seat will fit most normal folks.... the King will sit you back 1 1/2 inch for the longer armed or legged few..... same height and width, Pillion does have way more comfort and padding than stock...many ways to get the seat,,,,with or W/O back rests and two colors, Red and Black, for the Carbon Fiber stripe around the seat...the one above is black.... No issues with taking off the side panels with the seat on ... The price is the price and if your behind is not suited to the stock seat this one will do nicely !!!
