Hi, The really comprehensive parts manual I have from '69, specific to the SS or K0 model, lists them fitted to all but the UK market. I too had a K2 (1970), K3 (1971) and 350K4 (1973) in the 70's and they all had them fitted but I don't think the early K0's had them. There is no sign of them being fitted to the parts bike I have. I really like the K0 with the knee pad tank, chrome chainguard , hot cam and steering damper. Problem is some parts are rare (just like my 750K0) and the tanks are a favourite among cafe racer builders. Also the engines are sought after by classic racer fraternity. The Japanese domestic market bike from '68 had a CB72/CB77 style tank and oval combined instruments. Never seen one in the 'flesh' though.

Hmm - just looked at the K0 on James May's Man Lab (Sardine Blue one) and it has indicators - maybe they were not fitted in early production and fitted in late production, or as the guy on the US site says possibly an optional extra.
Cheers
