I haven't tried it but a sheepskin cover is supposed to be really good. Cut an old coat or rug up and sew some straps on. Mike.
I'm not to please with the comfort seat I got with my 2015 blade, luckily I managed to get it as my present from Farnham Honda when I purchased the new bike. But I have to admit it's not a lot better than the standard seat. A bit disappointed in it to be honest. If I'd paid the retail £189, I'd be even more disappointed.
