Let me preface this by saying that as a rule I don't supply customer feedback on products I buy. But when you finally find a solution to a long standing and common problem it never hurts to share. I have a 2006 Yamaha FZ1. Been riding for forty years and this is by far my favorite ride so far. Love everything about the bike except the seat. The engineer who designed it obviously had no intention of riding it. So I quested for its upgrade. I broke down and invested in a Corbin seat as I had heard good things. It arrived and I was struck by three things; the craftsmanship was impressive, the fit was perfect and the feel was no better than the stock seat it replaced. However it did set me back $300 so it had that going for it. So my ass suffered for the better part of a decade and then I read about Airhawk products. I was eager for a solution but reluctant to get burned again so I sat on it for a while so to speak but finally pulled the trigger and got the R model this winter and anxiously waited for the damn snow to melt so I could apply it and try it. Well I finally was able to get a few good rides in between spring rains and am happy to report apparently finding the solution to my pain in the ass problem. Mind you it is early in the season and I will reserve final judgment until the end of this riding season but so far tests indicate that this year’s long rides will be free from the nagging pain that previous years was certain after the 200 mile mark.
