Hi - new member here. I own a few Honda twins (CA77,CB77,CB450K0) and have had a few others. I am finishing the "freshening up" of a nice 67 Bomber with 5K original miles, it runs great and is a blast.

Does anybody make reproduction rubber parts for the seat hinges? Mine are intact, but I worry that they won't stay that way. Also, the seat foam is crumbling under the original cover. I am considering having an upholsterer carefully remove the cover and replace the foam, and reinstall the cover. Has anybody else done that?

Here are some pics of my Bomber.

Gordon East can get them made.
Don't how to find him. You'd just have to search threads.
I know he has been here and over at http://kawasakitriplesworldwide.com/phpBB2/index.php
I also know he's a member of the vintage jap motorycle club.

If I can find him I'll let you know.

Great looking bike, I want one !!!!
I am also looking for foam for my CL450. One time i did take a seat to an upholsterer for new foam. He had some stuff in stock that when we looked at it seemed like it would be fine but it wasnt as dense as what the original stuff was when new. I would be interested in a source for foam that others have used.

Sorry I can't help you with the hinges/foam, but I must say that's a great looking bike.

Thanks for the compliments - which should go to Honda for a great design! I was lucky enough to find a low milage original owner / original condition bike, and have only had to do cleaning/polishing, and repainted the black and silver (professional painter - not me), but not the frame. I am a cautious about taking apart what looks like a very nice original seat, and trying to replace the foam and ending up with an improvement. The problem is that the foam is just crumbling away, and it is now uncomfortable for a ride of any duration.

Hi Scott
The bike is super, wish mine was as nice, but a 12 year sejourn outside exposed to the elements didnt help, but thats another story. I had the same problem with the seat foam and rubbers. The foam seems to be purpose made and its not just one single block its has cavities within the foam (or at least mine did) that were rectangular. Additionally the problem was that the seat pan had rotted beyond repair, so my only option was to buy an aftermarket replica with a plastic seat pan. (if you look at my page you will see pics of the bike and seat). Not ideal but when needs must. Bill did say that someone had had some of the hinges made up, and was going to try and find the original email. I guess that he was not able to as he has not come back to me, which is unusual for Bill. Currently I am still using the old rubber hinges, its ok but not great.

Regarding the seat hinges with rubbers, Gordon had one batch made up by a local engineer. He kept the ones he needed, sold most to guys on the old CB450 DOHC forum. He returned any "profits" to the engineer that made them. That was a while ago now. I guess there is sufficient interest for another batch to be made up and sold on to members on this site.They were excellent and looked virtually like the originals. I guess if Gordon could be contacted he would be willing to give a contact number for the engineer if someone wanted to organise this. For those of you who dont know, Gordon's rebuilt BB is probably one of the best you may ever see.
Gordon was also responsible for having some of the rubber items made up which you see advertised on EBay.
I have not yet found anywhere that can supply the made up foam component for the seat. It is really quite unique in its make up - mostly out a pinkish
colour moulded (?) foam with a skelton type support. A specialised seat recoverer may be able to make one up but I thik it would be expensive.

Your bike looks really great. I can understand why you would want to sort the seat issue out.

Hi Ray
Remember we chatted at the Netley Police show this year. Incidently where has the summer gone, just as I got the Bomber on the road, but hey that's the rich quality of life in the UK.
I would definatly be interested in the seat mounts, although bizzarely the mount with the locking hand wheel has survived almost unscathed, but the others could definately do with replaceing.

Hi Nigel,

yes I do remember, we chatted at the emergency services show where my 66 CB450 Police bike was on display.You had front brake problems. I see in a round about sort of way you did as I suggested and replaced the hub.

I do have Gordons Email address if you want to contact him and see if he will give you contact details for the guy that makes the seat hinges. I think last time he made 30 sets which all sold fairly quickly.

By the way, the horn decals Chris has had made and which you were involved, really look great. I had asked Chris for 5 of them and hopefully he will get back to me when he is ready.

Is your BB on the road yet?

Regards, Ray

Hi Ray

Not been on for a while, yes the BB is on the road I took it ot the Popham mega Bike fest last weekend the only Bomber there I could see, which was nice also took the 650Z which a friend of mine rode.
The lables are on their way to Chris I posted them yesterday (27th Aug). If you know anyone else that wants some I have about 15 left myself, with the rivets too. I managed to source them.
Attached are the pics I just took today of both bikes.
Please could you send me Gordons email address.

Nigel

Pictures look good Nigel. Pleased to see the BB is on the road. I can now see the chrome front mudguard goes with the K1/2 forks. Guess your still looking for the K0 forks? Maybe someone out there has a steering knob for you? The CB72/77 will fit until one comes along?
I am sending Gordons Email address to you in a PM. Perhaps you can ask him for a picture of his BB with permission to show it on this site? Probably one of the best around.
Regards, Ray.

Hi -
Yes - I know Vince well and ride with him. Please let him know of my superior photographic talents! Just kidding of course - he is a fantastic photographer, and a crazy biker. I think he talked about you possibly coming to the US for a ride - looking for a superhawk. I also have a superhawk (not modded like Vinces).

Great looking Bomber!
You can get seat hinges from Clausse Studios in California. They sell sets on ebay as well. They are the folks that are making reproduction rubber for all of the old Hondas. I found a NOS rear passenger peg for the 450K0 and sent it to Greg to make a mould and he sent me back a complet new set. You can call them and check but I cant see why you couldn't clean out the old rubber and have him recast them with new rubber. I am going to do that on my Red Bomber when it's time.

The seat foam is a problem. On the old Hondas they used a dense pink foam in blocks with spacers and then used a different foam in between these blocks in some cases. When the foam started to let go they fell over like dominos under the cover. What some restorers do is take the cover off and reglue the blocks back in place add new foam in between and then lay a new thin sheet of foam over the top and shave it to the profile of the original seat and then put the cover back on. The trick is to find someone who has info on where you can get the dense pink foam to rebuild it with new foam!

I purchased the plastic seat from David Silver Spares a couple of years back to take it apart and use the foam with a correct cover. Sirius consolidated has a good cover for around $60.00 with replacement rivits out of Canada on ebay. The plastic base units are available from CMSNL or David Silver Spares but don't have the correct grey piping on the cover or you could use that. I purchased a NOS seat in a box and the foam is brittle so it could only be used on the bike as a display. I would love to find someone that could use my seat to make a mould of the foam. That's why we love these bikes. They are never finished! Good Luck! Great bike!

Hi,

I just bought a '67 Black Bomber and the front latch and rear hinge. Might you be able to send me a pick of those on your bike?

Best,

Amir
