I rode out to the Corbin factory a few weeks ago and had a custom seat made. Since then, I've logged about 1,300 miles on the new seat, so it's "officially" broken in according to Corbin (they say it takes 1k miles to break in one of their seats).

So here are my thoughts...


Seat Manufacturing

The Corbin factory was very nice, and the employees were all pleasant and professional. There's a restaurant and a comfortable area where you can sit while you wait for your seat to be made from your exact measurements. A seat "Wizard" looks at you on your bike, makes suggestions, takes direction, makes the requested changes, and brings the pan and foam back and forth several times until you’re happy with the fit and feel. They also insist that you take your bike out and ride it for a while in between the tweaks and changes, just to make sure everything is exactly right. Only then do they move forward with making the upholstery pattern and pass the seat off to be upholstered. They do not charge you anything extra for the ride-in, custom seat service.

Julio was my assigned Seat Wizard ;) Super cool guy (who rides and R1 btw)








Fit & Finish

The first thing I noticed is that it fits very snugly on the bike. There's no slop or wide gaps like there was with the stock seat. When it was fresh from the factory, it was actually a bit challenging to get the seat on and off. I had to lean in and push down with all of my weight on the rear of the seat to get the key to be able to turn and unlatch the seat. I had to push equally as hard to get it back on. Now that it has been on the bike a while, the round rubber pads that support the seat on the frame have broken in and it pops on and off much easier.

The materials are top notch, but this is something Corbin is known for. Unlike most, if not all, aftermarket seats which are covered entirely in vinyl, the seat portion of all Corbin seats is covered in leather... which breathes. I've found that this fact keeps my butt from sweating as much, and it doesn't seem to get as hot as vinyl when the bike has been sitting in the sun.

Also, as a nice touch, the portion at the front of the seat that contacts the gas tank is covered in a very soft leather.



The finished product.











Now for the nit-picky stuff...

There's a thin piece of plastic between the upholstery and seat foam. It's probably there as a protective later, but when you push down on the foam you can hear it crinkling (like a plastic bag).

Here's a pic of it peeking out



Anyway, that material is causing a weird FLA (Fat Ladies Ass) affect on the way the vinyl sits on the rear "hump" portion of the seat. You can only see it when the light hits it a certain way. I tried to take a picture, but again, it's very hard to see. Looks a little lumpy. I haven't decided if it bothers me enough to take it back and have it addressed. But I probably will.




Comfort

Honestly, this part can be tricky because it's really subjective. I've had Corbin saddles before, so I knew what to expect. The Comfort Cell foam they use is firm and supportive. The Corbin seat on my FZ6 is well worn at 70k miles, so I had forgotten how hard a Corbin seat feels at first before they mold to your butt. There are no hot spots with the Corbin, and though the initial comfort level is somewhat less than a stock saddle, after breaking it in it’s very comfortable. And since the foam doesn't break down, you’re going to have this seat until the vinyl or leather rips with little to no change in comfort level. If the vinyl or leather ever rips, you can send it in and have it recovered... nothing else needs replacement... ever... and everything but the upholstery is warranted for the original owner for life.

Another feature (or flaw, depending on your philosophy on adding weight to the bike) of Corbin seats is its broad, supportive seat pan. The base of the seat is made with stiff, heavy Fibertech plastic. It adds weight to the bike (as well as a touch of seat height), but it allows the seat to be wider, and cradles your buns nicely. I also noticed that the new seat pan doesn't have the weird curve at the front that allows you to see past the frame and into the innards of the bike and the base of the gas tank. The pan is also wider where your thighs sit, which forces your legs out further when putting your foot down and may be a problem for those that have a conservative inseam.

I rode down to LA from SF, which was a little over 450 miles and about 8 hours with stopping for gas and meals. I never felt any hot spots, but I did start shifting my weight and feeling a little uncomfortable around 400 miles in. While I was down there I rode Angeles Crest Hwy and noticed that the way the thigh area of the seat had changed (discussed above) forced my thighs out and away from the side of the tank and it felt like I was having to put more effort into getting a good grip on my tech-spec tank pads. The ride back to SF from LA, I started getting uncomfortable earlier, about 300 miles in... even though the seat was broken in more. But, that was a fairly unpleasant slog in general. I was riding into a really strong headwind that was beating me up and blowing me all over the place, so I was pretty miserable... which probably didn't help my feeling like I wanted to get off the bike ASAP.

All in all I'm completely satisfied with the seat and would spend the $493 again in a heartbeat. There's no way I would have even considered making that trip to LA on the stock seat.

Here are some Corbin vs. Stock comparison pics










I'm probably going to update this as other things come to mind, but at the moment I'm tired of sitting at a computer... so I'm going to tentatively say: The End :eek:

great review. I had a corbin on my old 998 SuperChicken and loved it. I do want to try and hold out to see what sargent comes up with (if they ever do), but I like the way yours came out. Love the "fat womans ass" reference, I knew exactly what you meant! If corbin made a solo saddle with just a cowl on the pillion I would be in.

No idea.

My fancy digital-BMI calculating-WiFi enabled bathroom scale wont register anything for either seat.

Dude.........

Step 1. Weigh yourself. Record value.
Step 2. Weigh yourself holding one seat. Record value.
Step 3. Weigh yourself holding other seat. Record value.

Voila!!!!! You now have the difference in weight!!!!!

This would completely ruin my current "Ignorance Is Bliss" weight-loss strategy.

Thanks.

What leather did you order. Is it the carbon fiber weave?
Yes, the leather portion is carbon fiber weave, as is the vinyl... but the vinyl comes in two different versions, regular and high gloss. The sheen of the high gloss vinyl looks very different from the leather, and I wanted it to look as uniform as possible, so I went with the regular non-high gloss version of the vinyl.

Thanks for the info. I like the look of you seat. I'm not a fan of the regular Corbin seat for the FZ-09. Is your seat the Gunfighter but with different covering?

No.

I went completely custom.

Their "Gunfighter" version didn't appeal to me... which is why I rode down there in person.

Here are the measurements for my seat.

Thank you! Great review! Do you feel like the seat is detrimental to aggressive riding compared to the stock seat?

OK.

Stock Seat = 4.7lbs
Corbin Seat = 8.6lbs

And now I've been made aware of the fact that I'm at an all time high weight wise View attachment 6346

Someone owes me a light beer View attachment 6345
Hahaha sorry mate. Bugger the light beer!!!

I dropped 30kg (65lb) recently just in anticipation for taking receipt of my new 09 lol. No better mod to the performance of any bike than dropping 30kgs from it!!!!

I bet my previous Ninja 300 would go much better now!!

Cheers for the measurements on your custom seat too, many wouldnt do that for the sake of keeping it a one off..............top bloke.

Thank you! Great review! Do you feel like the seat is detrimental to aggressive riding compared to the stock seat?
Detrimental, no.

Different, yes.

The biggest challenge with the seat during aggressive riding was re-learning and getting a new feel for my knee and thigh interaction with the gas tank. Like I mentioned, I struggled with getting a feel for the Tech Spec tank pads, and this was most pronounced under heavy breaking when the bike was upright. I was squeezing the tank with my thighs like I normally would, but I was still sliding forward... between the the seat keeping my thighs further from the tank (and the knee armor in my pants also hitting the Yamaha tank pads before my thighs would contact the Tech-Specs), I could never seem to squeeze the tank tight enough to maintain my seat position under heavy braking.

I feel this problem is two fold.

One, the seat changed.

Two, my pants changed.

I normally ride in leather, but recently acquired Rev-it riding jeans, which I wore on this trip. I think some of the sliding forward was the Kevlar/Cordura on the seat vs. leather on the seat. AND Kevlar/Cordura on the Tech Spec vs. leather.

I'm going to buy a "generic" sheet of Tech Spec material and cut out pieces to stick atop the center of the Yamaha tank pads and see if that helps.
