took my first ride on my Helix with the new backrest, today. (and first January ride..ever?) I like it, but it was a really odd feeling. I've never ridden anything with a backrest..and the feeling of not being able to move around on the seat was..odd...but my back sure liked it! I did my typical ride, about an hour and just under 30 miles. Usually I'd feel a little something in my lower back after an hour ride but I felt nothing today.
I could really notice the backrest when opening up the throttle or accelerating up steeper hills. Usually in these instances your core muscles come into play to keep you in the right position. With a backrest you just lean back a bit and enjoy the ride!
I think I'm going to like the backrest. It will sure make putting miles on much easier.
