I just rode my 2007 FLH Champion IRS conversion with its stock saddle to Bikeweek in Daytona (from Dallas) and for the first time I didn't have a duffle bag full of clothes behind me on the passenger seat. The lower muscles in my back got real sore. I went to the Mustang Saddle people at Destination Daytona to purchase a backrest. They removed the seat and concluded that the stock Harley backrest bracket would not fit on my trike. Does anyone know if I can put a backrest on my 2007 Champion conversion?
