Received the backrest/rack and I installed it in less than ten minutes. I used the allen nut that comes with it in lieu of the knob. If someone really wanted it, they’d take the whole rack assembly as long as they had the right wrench. There is no adjustment up and down, but about two inches fore and aft, not incrementally either there are two holes to choose from. I took my 9 year old for a short ride and he likes it. I like the added security knowing I’m less likely to leave him on the road. My bride hasn’t been on the bike yet, she hasn’t been fitted for a helmet yet, so no criticism/comments from an adult passenger yet. I purchased the “Universal Helmet Bag”. I like the rigid frame and it flows nicely with the lines of the bike. If you wear a full face helmet (Arai XL in my case) good luck getting it through the hatch! It’s quite small. . . I didn’t buy it for a helmet bag, just extra storage. I’ll post some pictures when time permits. So far I’d give the fit and finish a ten, the design of the bag an eight, the adjustments a seven.
