Corbin seat with Givi wingrack

Hi, does anyone have a Corbin seat with the Givi wing rack on their 4th gen? To my dismay I am unable to latch the seat with the wingrack mounted, it latches fine without the rack system. The seat contacts the rack where it bolts to the upper rear part of the subframe (where the grab rails normally bolt). Looks like I have to modify the Corbin seat pan in order for it to fit. If anyone has any suggestions I would greatly appreciate it. I do not want to have to modify a brand new seat. TIA.

 

Please accept my humblest appologies....it's a 4th gen (1997).

 

That's weird... can you use the seat with the passenger grab handles then? I dont' have a corbin, but my Sergeant was specifically built/cut to accept the grab handles and has plenty of room for the givi wingrack2 on my 98.

 

I don't have the grab handles for my bike so I can not check...I was wondering the same thing. The Corbin does have the cutouts on both sides, if it had 1/4 inch more i am sure it would fit just fine. Even the stock seat touches the brackets, but it still latches in place.

 

the wingrack isn't bent is it? I know mine was a bit "off" when I bought my bike from the owner tipping the bike in his garage....


how tall is the rack mount? from like the bottom of the flange that bolts to the subframe to the top of the tube that goes out the side? I can go measure mine for comparison...

 

From the bottom of the flange to the top of the bracket is approx 3/4 inch give or take a 1/16th. The right side is a little higher by about a 1/16 than the left. Not sure if maybe the bike fell on the right side and bent the bracket up a bit? Still have a long way to go for the seat to latch down tho approx 1/4 inch. Also have about 3/4 inch between the fairing and the top of the bracket (forward section). I am curious to see where your bracket measures at. I did remove the metal collar from the grab handle bolt so the bracket sits a little lower, but it still was not enough for the seat to latch. Thanks so much!:thumbsup:

 

I'll take a look after dinner and maybe even grab a picture so we can see if it's similar setup or not as fars 4th gen vs. 5th gen and the original wingrack vs wingrack2

 

Measurement seems the same. If I measure from below the flat mounting bracket it's just over an inch and if I measure from the top of it it's around 3/4". Here are some pics how it looks on my bike:










Are you 100% positive that the luggage rack is preventing it? Are you sure the locking mechanism isn't jammed?






In other news...my sprocket finally went lol...whoooooooooops!



I knew it was due soon but last two weeks ago was the final bang. Damn...need a new chain too prolly. Bah. At least I already have a new sprocket...no more aluminum bullshit for me!!! Bastard took about 19 teeth out when it slipped (I never noticed it though) Having a sprocket with nubs is kind of funny sounding if you've ever worn it down that far lol...sounds like a little machine gun if you slip it ...horrible for the chain and sprockets obviously...

 

Whooaa...crazy on the sprocket bro!

I am absolutely sure it is the seat contacting the brackets. I took off the rear fairings and tried fitting again so I could have a good look at the latching mechanism. There are two rubber feet that should rest on the latching bracket. They are at least a 1/4 inch from doing so. With the bracket removed the seat snaps in just fine. Thanks again for your help man I hope you get those sprockets and chain fixed soon!

 

I will. Like I said, I already have the sprocket on hand to change this winter, but I didn't expect the old one to give out on my last ride lol...so now I'll order a new chain while I'm at it. No biggie. I'll have it back on by the end of next week.

Not like I'm going anywhere soon for long....still too much ice on the road and it's going to be rainy and 40 the next couple days...so yeah.

 

Here are pics of the Corbin versus the OEM seat, you can definitely tell that the cutout is smaller on the Corbin. I guess I will have to drill out some of the rivets holding the cover in place, remove, and dremel out larger cutouts. Gotta go buy a rivet gun 1st. Thanks for everybody's suggestions!:thumbsup:

 

I had the same problem on my corbin seat and my wing rack on a 4 GEN. I had to drill out the rivets in the rear portion of the seat cover then fold it back and grind down the fiberglass seat pan until it fit good over the mounting rails.

 

Thanks so much...I was afraid of that.

 

I had the same problem with the first Corbin I had on my 5th gen, it's just Corbin's typical attention to quality control. Mine was a beat up used seat, I added some shims under the u-lock to raise the seat just a little to clear the Givi mount, that along with some strategic slamming and banging of the seat on the mount and it fit just fine. If you feel like being yelled at you might try calling their customer service.

At least the seats feel good. :biggrin:

 

Search words: Givi, 4th gen

Tangentially related to your post. (Thanks for the great pics)
Just bought an "old" Givi rack and bags for my 4th gen, 96.
It has two connector tabs that drop down below the rear fairing, and doesn't involve the grabrail mounts. The new Wingrack seems like the best solution to engineering the mounts. (although the look of them is not for me, probably would have gotten one eventually just because of the quality and the efficiency)
Did Givi re-design the mounting system from my old one to the new Wingrack because of problems?
Mine is going on no matter what, but I could modify it or reinforce it if I knew of problems.
Thank you for anything you might know about Givi racks.
Enjoy your weekend, boys!:smile:

 

Maybe your mount system does not have the option for side bags?

 

Hi Red, I am not sure why they redesigned the rack, but it does incorporate a rear top mount for another bag and looks beefier than the older one. The drawback is that the new mount is really heavy and I can feel it on the back even without the bags. The rear subframe on the 4th gen are really "flexy" and you definitely feel it back there when all that weight is that high and far back. When making any type of semi-aggressive manuevers it almost feels like the old gal is "wagging her tail".

For all the other guys who may potentially have problems with this set-up...here you go.
It was pretty easy to modify the seat pan once you got past the fear of drilling into a new seat. Here is the seat after I drilled the rivets out and peeled the leather/vinyl back. Notice where the seat pan makes contact with the top of the Givi mounting bracket.



Here it is after I took the old trusty dremel to the seat pan. Make sure you leave some room for the vinyl when you stretch it back over.



Finished product (after doing the other side as well).



I did also notice that the new seat is "buzzier" than oem while accelerating between 5-7.5k RPM. When fitting the seat without the rear fairings on you can see that a few of the rubber bumpers on the underside of the seat (right in the middle) does not make contact with the subframe rails. I am hoping to solve this problem by drilling the rivets out on rubber bumpers and shimming them with washers. This also gives you the opportunity to make sure the rear latch is catching all the way. The rear bumpers are screwed in and you can adjust by adding or taking away any washers. From the factory they come with 2, so I just took one off on each side and it was perfect. The seat snaps right in place and releases as it should. At first I would have to push the rear of the seat down while pulling the release to get it to unlatch. Make sure you do this before modding the seat pan.
Despite these problems the seat does look really nice and is more supportive. I had the Wifey sit on the back and she gave the nod of approval.:thumbsup: I would like to thank everyone that contributed to this thread, it definitely helped me out. Take it easy!

 

Friday Night Live! (Thanks for being out there)

For me, SLOVFR?
Only for side racks. That is maybe a reason they went away from it. The two connector tabs drop down, not up, so I don't see anyway you could extend it to a top case. They probably sold a separate piece that piggy-backed on the grab rail for a topcase. (home made "solo rack"seen on VFRD, just tonight)
Before I purchased, I internet researched for months and found precious little on this item. Maybe they sold poorly, broke too easily, and are wandering with the white buffalo.

 

Kick Ass pix, Flippy!

I try to photo my little jobs and it comes out white, blurry, or both.
Can tell from the photos that yours hugs closer to the frame, too. I'll bet mine has some shudder at speed.
European market probably made their design better and better.
