Hi
New guy about to buy a CB750F to restore, wonder if someone could help me identify a bike from its Vin Number.
Its supposed to be a CB750F 1980 and has KPMH speedo so guessing European

Vin number is RC04-10139xx (All the documents Ive found so far say cb750f numbers start from RC04- 2000001)
Engine number is RC01E-41029xx which I think makes it a CB750K. Are there major differences between the K and F engines?

Really appreciate any help, dont want to buy unless the numbers make sense

Thanks in advance

Engine wise, this post might give you some useful information (its comparing 79models)

CB750KZ 1979 and CB750F 1979 Engine Differences

I’m trying to understand, what if any, difference there is between the engines on the 1979 CB750K DOHC bike and the 1979 CB750F DOHC bike (called the CB750F-A in some markets). I was sure that I had read somewhere that the CB750F DOHC bike had different cam profiles and larger valves than the...

Thanks for the reply - A bit more info that might help someone else. I think my chassis is a Japanese bike. Based on using cmsnl.com who allow you to put a vin number in to search for parts. And they recognise RC04-101 as HONDA CB750F 1980 (A) JAPAN RC04-101. And I think Japs use KPH speedos. After extensive searching it was the only website I could find that recognised the RC04-1
