Topic: goldwing front end

[dusterdude]

there is a 78 goldwing front end on ebay for a good price(at the moment).what issues would i have installing it on a k1 750.thanks

Havent loked at the sale but you need the COMPLETE braking system The complete front end with trees and wheel and you will have to mix and match headrace bearings

I think 75-77 is the year when the stem length is perfect and the swap is a bolt up. I have heard about guys putting 78-82 front ends on cb750s but there was some mod that has to be done and I don't know what it is. With enough mods anything can be swapped onto anything. I do know that the aftermarket wheels are the same for a 1978-82 gold wing as they are for a 1977-1979 cb750 supersport (the lester wheels carried the same part number for both applications).

IIRC the 78 should be a mag wheel on the GL, the 1975-1977 is a spoke wheel with an aluminum rim that blends better with a cb750's spoke rims.

yea,i have to put about 150.00 to 200.00 of work into my front end this winter and was just thinking about alternatives.

I got my 1975 Goldwing front end for about that much. You just need to be at the right place at the right time. I got it because I saw someone was parting out a GL1000 on ebay and before he posted the front end I shot him an e-mail and told him i'd buy it.

I really think I should make a bracket to adapt a modern caliper to the front of these bikes. If the kawasaki triple guys can do it why can't I?

[Henry Dorset Case]

thats my feeling too.  I have in mind a project CB550 F1 cafe style but with modern USD forks and BFB  (big f.... brakes).  more for looks than anything I admit, but the mental pix I have is very cool indeed.

Guys,
Speaking of front ends... can anyone tell me what i have here?

I picked up a parts bike - ex. post-classic racer
The frame is k1 and i think the front end may be F2 (?)

Fork brace, alloy rim etc.

I want to put it on my otherwise stock K1

how about a pic becasue your description doesn't leave much to the imagination.

An f2 would have a comstar so if it has spokes that is out. an F1 or F0 (1975-76) are single disc spoked rim, and pretty close to a stock K bike setup except for being a little taller and not having a front strut on the fender.

The only spoked aluminum rim would be either a cb750A hondamatic or a 1975-77 GL1000 goldwing. The gold wing is easy to spot, the top clamp risers are higher than stock cb750, the forks are 37mm (vs the cb750's 35mm) and the wheel would have dual disc. Also the lower fork legs have three rings cast into them as a styling cue. A cb750A front end would look just like a stock cb750 front except for the aluminum rim. Stock aluminum rims are DID. Plenty of racers lace alloy rims to stock cb750 hubs, so it could be that also.

As for the fork brace, if it isn't part of the fender then it is aftermarket, as all cb750's had their fork brace as part of the front fender.

sounds liek you either have someone's hopped up roadrace front end or a modified chopper front end.

Sorry,
Just realised the pics didn't attach...

I'll put them up when i get home

Oops!!!

Did you read my reply yesterday Brooksey? Definately not an F2, probably a CB450 or CB500 front end with dual disc conversion. Here's a pic of a proper F2 front end. Cheers, Terry.

[Brookesy]

Thanks for the replies guys.

Terry,
Yeah, i saw your reply after i posted this...


I've done some more investigating on the weekend and i'm pretty certain they're F1 forks etc.
I won't actually know until i go to get seals etc. to rebuild them.
The fork tubes are 35mm dia. and the triple trees etc. look like F1
The actual brakes and discs etc. look like F1 when matched up to some pics i have
They're going on the K1 since they look the part but are better brakes than the original K1 item.
I'll be replacing the discs with something better though - and i'll have to make a mudguard that will fit with the fork brace on -
or leave the fork brace off and source an F1 front guard
The idea is to have something that still looks original(ish) but handles / brakes a bit better

I'm still not sure about the front wheel though.
The bike is an ex race bike so i could be anything.
The hub doesn't look honda at all - maybe it's an aftermarket race item??

The other project will be i bit more radical - USD front end and 6 pot brakes etc - i'm trying to use only Honda parts but we'll see how it develops
I may go with a monshock rear end but i'm not sure about that yet.

[Terry in Australia]

No worries Brooksey, if they're F1, they've been modified slightly, maybe just had some material shaved off on a lathe on the lowers. If you need an F1 guard let me know, I've got a couple here, and I'd trade you for that fork brace.

I've also got some Nissin GSXR 4 piston calipers, if you want them for your "radical" project. Re: your wheel, count your spokes, if it's got 40 it's probably Honda, both Suzy and Kawasaki used 36 spoke hubs, and I think Yamaha did too? Looks like standard Honda discs though, and it was a common race trick to turn the hubs down on a lathe to reduce the unsprung weight. Cheers, Terry.  

[Brookesy]

Terry,
The fork brace is worth more than the rest of the bike
Should look nice polished up - maybe with a carbon fibre mudguard?

I'm having fun with ideas at present while i look out for parts.
Not enough spare time or money

ok,i won the front end,if anyone has any advice on installing this please feel free to chime in.thanks

Carefully pack it in a big box and send it to me mate, and I'll modify the "trees" to suit a 750. Oh, and then i'll send it back to you, eventually...................... Ha ha, seriously though, you'll have to play around with steering stems, I'm sure they're different sizes, I've got a taper roller bearing kit for each bike so I can measure them and see what the difference was, but I know it's a pretty simple mod, Patrick Bodden built a magic RC750 rep for Cycle World in 2001 that he named "Big Benly" and raced in AHRMA events in the US and Britain, and it used a "Wing" front end with a trick hand made alloy top triple, but utilised the OEM bottom. Sadly because the Wing forks are 37mm, you can't just slide them into your triples like you can with F2 forks. Cheers, Terry.

[dusterdude]

cool deal terry,if you would measure them i sure would appreciate it.thanks

No worries mate, I'll do it tomorrow after work. Cheers, Terry.

[dusterdude]

groovy

[dusterdude]

just for info purposes,i figured out my lower legs are 75-77,not sure about the trees yet.i am in the process of taking it all apart so i can measure the bearing mounts on the trees.film at 11.

[Terry in Australia]

OOPS! Sorry mate, I said i was gonna measure 'em and I forgot, I'll do it tonight after work. (Monday here in Oz) Cheers, Terry.

[Geeto67]

did you measure the caliper mounts? how did you figure out the fork legs are 75-77? Remember the GL1000 wheel is the best part, factory aluminum rim.
