Steering lock differences

[Davelu88]

Just been comparing my usa cb550f on a 75 plate to my new uk 550f2 on a 78 plate that I got from mickf ( many thanks mick) & I have noticed that on the USA model the steering lock is operated by the ignition  but the UK one has the old style one one the headstock . I was trying  to search for a new lock for it but on the cmsl parts ficsh  it does not show the frame as having it. Any thoughts on what would fit .regards Dave

Bit confused as to which lock you want

[Laverdaroo]

I'm in the same predicament, my frame has no boss for a lock and I'm not running a standard ignition so I think I'd resigned myseelf to carrying a chain tbh, think there's no other way of fettling this scenario

If you can get someone to weld a small metal bracket just under the top headstock ball race fitting you can have the steering lock inside the ignition.

I woiuld Ken but my frame's gone for paint, sent it before I left including all the polishing and other bits that needed painting/coating. I think its a chain for me.

The lock that goes sideways into the headstock is ebay item 371480375424 BUT the stem on the bottom yoke needs a slot in it for it to work

You can get an ignition lock that incorporates a steering lock as well Bryan, it has a steel pin which comes out of the lower front of it, in fact if you look at a 550 lock you can see the opening which has been blanked off, you weld what is essentially a half moon shape piece of metal on the ball race part of the frame, the steering is turned fully to the left and turn the key fully to the left and the pin comes out and goes just at the end of the new metal bracket, this stops the steering from turning but it only works at full left lock for some reason. My CB1300 has the same system as do most of the more modern Hondas.

Probably a chain for me too but thx for the replies

[Bryanj]

I think that was on the later F model anyway Ken, i just cant figure out from the question which one he wants

[Seabeowner]

The UK K3 shows a lock. Is this the sort your F has?

And it also shows the arc of metal for the ignition/steering lock, confused.com

UK and europe is in the steering stem , USA is on the ignition switch.
These look the same as the UK and was going to buy one but, don't have a bike to try it out

I went through the same with a CB400F2; mine was a Canadian model with nice ignition key steering lock, whereas the UK versions had you grovelling under the headlamp. My question is, why would Honda go to this considerable extra expense of frame variations and lock hardwares? (the 400F2 also had additional frame differences wrt pillion footrest mountings iaw international markets)

[Davelu88]

Sorry Bryan , I didn't explain it properly,  my UK model has the steering lock on the headstock like Seabeowner has stated on the K3 ,

[Bryanj]

So if you want the uk one its the ebay number i posted

I guess a simple alternative could be a short cycle style cable, run round a fork leg and a down tube. Not too difficult to carry and might even fit in the tool tray.
