Well, I never found a used Corbin for my 400 .... So, I bit the bullet and bought a brand spanking new one. $$$ Ouch. The only other new seat I have owned was a Mustang on my VN750 back in the day.
My initial impressions...
First off, I was little leary of buying a Corbin brand new b/c of cost AND negative feedback about their customer service. My seat came exactly 2 weeks after I ordered and was everything it was supposed to be. As you see in pics ... packaged extremely well. At these prices though I think they should have included a bottle of their leather conditioner. (And a seat cover, and a new pair of riding boots:-)
I expected the seat to be hard. It is not. It is firm, very firm but I would not describe it has hard. It supports my hinnie quiet well. It is 100 times better than the stock seat!!! After 600 or so miles ... 294 yesterday... and some tinkering with the backrest ... I'm really pretty pleased with the purchase. It looks awesome. Made the bike look like a whole different bike.
The seat raised me up about an inch, maybe inch and a half ... which is great. Still flat footing with a 30" inseam. Seems to be a little further back than stock seat with buttrest on. Could have been back a little more maybe ... but seems okay. Way less vibration felt in the hinder parts than the stock seat. And better shock absorption over bumps. (IMHO, shock absorption is one of the most under appreciated things about a new fancy smancy custom seat. Better shock absorption from the seat itself supports the lower back and hips better ... hence improving the ride.)
The only downside, besides the cost, is that I feel a little pushed forward on the seat. We'll see if this changes after break in period. If not I think I can shim the nose of the seat up a little bit?
I have a used Corbin on my 650. The Corbin on the 650 is better ergonomically ... IMO. The 650 seat is deeper and has better back support. But the Corbin on the 400 is a massive improvement over the stock seat. To me, worth the "investment" if you plan to ride a 400 well into the future ... which I do do. Of course, after spending $573 shipped, I'll have too ...






Used backrest off my used Corbin from the 650. It will move from bike to bike. Not a perfect color match but close enough.
