Maybe it depends on how much padding each person has, butt (sic), I found my skinny bum couldn't handle the stock Speedmaster seat for any longer than 3 or 4 hours. After that no amount of stopping would sort out the discomfort. That's when i began searching for an alternative.
As for the pad on the end of it, I had more sense to think my missus would ride sitting on it for longer than down to the coffee shop.
What I realised was, the discomfort not only spoiled what should have been good memories, it took my mind off the job at hand ie; it potentially was dangerous.
Now we realise we're all different and some don't have any issues with the stock seat but I knew if I wanted to travel half descent K's, I'd have to invest in something better.
Anyway after much talking to blokes on here I decided for various reasons a Corbin with backrest and the pillion seat as an addition when needed was the bpick up 8Â est way by far to go.
To date I'm still greatful I went this way and have never regretted forking out the extra moolah once.
