We talked with Utopia Backrest , the best rest on the market,about a backrest for her new RTS they are waiting for someone to send their seat [at a substantial savings] so they can prototype one for the new RTS,since we live in Southeast Texas and ride year round,I requested the first production model in hopes someone in a more inclimate winter would send theirs, my wife is not willing to part with her seat yet. For anyone unfamillar ,I have a Utopia on my Venture, and my wife had on both of her Goldwing Trikes and they are great completely adjustable, first quality.He guaranteed in on monday out by next monday.
