Installed backrest I had on order from Utopia Products. Truly is fully adjustable. Requires taking the passenger seat apart, but well worth the hour of labor involved. What a difference!! Beside's the risers, the backrest is the next best add on in my opinion and would recommend one to anybody without one.:choppersm
For sake of information, I bought my backrest from www.cruisencomfort.com. This guy makes them for the 1300 and the 1800. They are $150 and the quality is excellent. Bought mine this past Spring and I love it. Read the reviews on his website.
