Teds new project a CB500 K1 mostly version 0.5 circa 1972.
McCabe-Thiele (Ted):
On the riveted on frame plate the date of manufacture has been entered as 8/71.
You are right Julie I'm not fussed if the frame is a K0 or a K1 I'm happy that the frame is in good solid condition clearly having benefitted by Bryan getting the frame powder coated plus it's been his bike since June 2003.
If it is a K0 frame will this make any difference when obtaining parts? Are there easy ways to see the difference as regards the frame design?

So if its got a rivited VIN plate on it it's a USA frame as we didn't have the VIN plates on UK bikes until 1976. The easiest way to tell if its a K0 or K1 frame is to show us a photo of the seat lock assembly as they are totally different K0 to K1.
Here is our K0 seat lock. The K1 has a totally different design, it's a normal plunger type lock.

Whilst Julie is 100% right in pointing out that the biggest difference between the K0 and K1 was the seat lock I’m not sure if the K1 seat lock bracket wouldn’t also fit the K0 and vice versa. There is a slight change in the part number for the frame from 130B to 140B but whether the difference was in the positioning of the holes for that bracket or something else I couldn’t say.
My comment wasn’t meant to criticise the frame, it was to ask why when the title says K1 is it wearing a K0 frame, seemed odd. I’d imagine an 8/71 build date would also mean it’s a K0 rather than a K1.
It seems that K0 models are worth more as well, so a set of K0 cases may increase its value, need an engine number beginning with a 1 though Ted. The K1 engines all began with a 2. Strangely the K2 didn’t start with a 3, which you think would be the case. Both my K1 bikes have frames and engine numbers beginning with a 2 and the L reg bike has a build date of 5/72, so your frame being much earlier than that must mean a K0.
It’s not important as you say though, it’s just odd.
I had 2 sets of engine cases spare from way back in the 70-80s and both began with a 1, which is very odd as I never had or broke a K0 but I did buy quite a lot of broken engines back then but how they both ended up coming from a model that was never officially imported into the UK is strange.
I still have a set spare if you ever want to make the bike into a K0.

Yes the seat lock brackets interchange, it was fitted with a later type lock as the best recovered seat i had was a later type, dont know what was original as nothing was on it.
Julie, i fitted the vin plate and had to drill holes for it as i said above the stampings would disapear under powder coat.

Ah yes, I've just read about the VIN tag on a previous post Bryan, sorry about that. Ted, on the V5 what date does it give as being registered in UK?
