So I see good (mostly) and some so so reviews for the riders seating, but quite limited on passenger reviews. How does the better half like it? is there enough room with backrest? etc. etc....
The Summit "fills" the space in the passenger area more so than the stock seat. Tour Pak needs to be in the back position. We had the Heated Summit for about 800 miles recently. The heat and the seating position was great for both of us, but the seat shape is decidedly "flat" and had both of us squirming after about 90 minutes and ready to get off after 2 hours. I thought about sending it off the Astech for a re-work, I think if it had been "dished" it would of made an awesome seat.
I tried the Summit seat. Was not comfortable for me or my wife. After several seats we tried the Corbin Dual Tour. Now all is well. Please keep in mind what works for others may not work for you.
