CB750K7 Rear Shocks

[Craizeehair]

Hi all,

My first question here if anyone can help?

I have recently bought back my old CB750K7 and I would like to replace the rear shocks. I have read a few of the previous comments here and had settled on the TEC shocks as recommended by others. Unfortunately, I have spoken to them and they no longer supply these and won’t be stocking them again. A real shame as I’ve had lots of bits from them for my triumph and they have been excellent.

Does anyone have any recommendations for something currently available that they have been happy with?

Many thanks in advance

Greg

Not Honda experience, but heavy classic bike: I had a bouncy Norton Commando. I replaced the shocks with Hagon and am happy with them. I almost went for Ikons, which are meant to be better and re-buildable, but 2x price.

Hagon every time. Bit pricier but great shocks and we’ll worth the dosh plus the after sales support is great.

Thanks, I will take a closer look at the Hagons

Got Hagons on my 750F1 and are a vast improvement on the standard ones, for the F2 I looked for TEC ones but could not find them any more so bought some YSS ones from eBay, don't know how good they are yet as the F2 is a long term rebuild.

TEC and the likes seem OK for a show pony.

I've been using Ikon 7610-1296SP8 for the last 5 years after first wasting 170 quid on Jap made DS supplied shockers that started to leak after a year when the warranty expired.


Ikon prices might make your eyes water tho...

Ikon are just renamed Koni though aren't they. Not saying that's bad as I've always rated Koni shocks, get a pair I need to refurbish and sell as I'm using some old Marzocchi AG Strada shocks on my 500.

In the end I bought some YSS shocks and had heavier springs fitted, I’m no lightweight these days!

Any advice here though? I can’t wrestle the existing shocks off, they are held tight by the rubber inserts, also the new shock eyelets are much bigger then the mounting, any suggestions as to how to remove the old shocks successfully without causing any carnage and are these just the wrong shocks or should I have some kind of insert perhaps??

Prize the edge of the rubber bush up a bit and get some WD40 in there using the thin nozzle extension between the bush and the mounting. You will probably have to do it in a few places to allow the WD40 to penetrate. They are not mechanically fixed, the rubber bush is just very tight.

Cheers, I guess I also need a new bush of some sort for the top mount of the new shocks, or can the existing be used again in them, they are far too big?

The rubber on the new shocks actually look ok to me, the stud it fits on goes much bigger after the thread part so it could well fit when the old shock is removed.

Aaaaahhhh, that would make sense. The thread is 10mm and the new shock rubber is around a 15mm opening.

Thank you,

I will have a go at getting them off and the new ones on over the weekend now I feel a bit more confident.

Have you tried removing the lower bolt and then just moving the shock front to back whilst pulling at the same time, usually works.

Yes, I had presumed it would slip off pretty easily but I think it’s going to need some persuasion!

I’ve moved onto the Bonneville brakes for this afternoons tinkering. I’ve always had bikes on and off since my teens but only recently started to get stuck into the work needed on them myself. I’m no stranger to using tools but spannering on a bike is pretty new to me, so I am a little cautious... as you can probably tell!

The more I do, the more I love it.

After WD40 spray you need the pull whilst wiggling left to right and up and down routine best to wear gloves in case it suddenly lets go. 😁😁😁
