CB750K4 (1974 US model)

[MCTID]

I need to buy a pair of new Fork Stanchions for my 1974 CB750K4. Looking on various websites, it seems that there are a number of different Overall Lengths available.....580; 583 and 607mm but the various adverts don't state which length Stanchion fits which model or years. They don't quote part numbers either........DOH.

Can anyone please advise which length Stanchion is suitable for my bike.........and why there are different lengths available. If anyone can recommend a particular Supplier, that would be great. Many thanks.

The fork section is about half way down this doc.

Hope it's of some help

The lower fork legs are stamped with '341' on the internals for models K3 to K6, I have posted a photo from my spare set of folks

A couple of notes

*  The lower aluminium fork legs K0-K6 total length are 335mm
* -------------------:---------------K7,F,F1,F2 total length are 370mm
* The K0-K2 has different internal fork tubes

My apologies to Big Al and Pablo.......but I am asking about the Overall Length of the Fork Stanchions....or Fork Tubes or Fork Pipes as Honda call them. The lower part of the Forks are called Sliders - well that what Triumph folk call them anyway. The part number for my Stanchions - K4 to K6 are 51410-341-702 (thanks Pablo) but I need to know the Overall Length so that I can buy the correct ones. Regards.

Excuse me for pointing this out and it may be construed as a bit of a girlie response but, why don't you just measure the old ones ?

You're not the only one who wondered Julie. Guess there's a reason, wonder what it is.
You have the part number and want to know the length. I turned to Mr Google, typing '51410-341-702 length' as a query.
Got 401 results, this was the first in the list:
http://www.rawpowermotorcycles.co.uk/PBSCProduct.asp?ItmID=12743654
This gives the length as 580mm.
Not sure about why there are different lengths available, maybe Mr Google could help there too.

Excellent answer Julie!...

www.cmsnl.com refers to the 'fork bottom case'...leg?..slider? & the fork pipe..tube?

Why not ask www.cmsnl.com for the length of their stock tube

The K0-K2 tube can be eliminated as its a different design, so is the K4 the longer or shorter tube?
Let us know how you get on

[MCTID]

Thanks Julie...........not a daft question......but look at the attached photo for the reason why I cannot measure the existing forks! Also, look at the handlebars if you want a really good laff......must have had a Chimp as the last owner.

It seems like 580mm is the correct Overall Length for K4 Stanchions......after doing some further research.....but I would still be interested in why the dimensions range from 580 to 607 for the available Stanchions.
Thanks to all who replied.

Oooooops, I see what you mean now  I wonder if the PO slid off the back very often ?.
I'm pleased your putting it back to STD, it will look a lot better

[hairygit]

Your a brave man to even admit to having bought that, and what kind of lobotomy was performed on the american idiot that did that to it? Maybe Julie can give us a clue given her medical background!

[Nurse Julie]

  The PO must have been on drugs and, if he wasn't he bloody should have been

[royhall]

Well I like it . I was wondering who had bought that, not sure if its a runner but I would love to give it a go before its stripped. What a laugh that would be.

Would not want to go into a corner too fast with those forks fitted

Well if I am to be brutally honest.....as I sat down on the sofa holding my iPad (steady now) I accidentally 'Bid' for this heap.....honest - and don't ask me how I did it (my Wife was also somewhat skeptical when I sheepishly told her a couple of days later). At the time I was just browsing to see what it fetched......anyway the Bid was automatic at £680 so I thought that it was bound to go for a lot more......it didn't!!!!!!! hence me now owning it.

Good things to come out of it are: The seller was really helpful in getting it to me; Peter Swift of PJS Transwift Ltd (www.motorcycledeliveryservice.co.uk) was brilliant in shipping it from Swindon to Lytham St Annes (£150 well spent); and most importantly, underneath all the crud lies a rather good machine.......so far everything that I have undone or dismantled seems to be in good condition and as original.

Although I have owned a CB750FN and two CB1300's before I am amazed at just how big and solid this motor is and for the dosh I paid, I am very pleased.

I will post some more photos and a list (a long one I'm afraid) of what I need so other Forum members can laugh - or cry - or help me out........

Sidetracking on a thread slightly (so nothing new there ....)
I too used PJS Transport when I bought my 400. Chosen on the basis of reviews and price, I too was very pleased with the service.
I thought his name was Peter Shaw; maybe there are two Peters doing the job.
