This is the reply i got from honda after asking for a certificate of conformity;
Thank you for your recent application for a Certificate of Conformity (COC).
I have been unable to print your request, due to one of the following reasons, as the motorcycle is too old, is an off road bike, or it has been imported.
You can apply for a ‘Year of Manufacture.
Honda (UK) can issue a Year of Manufacture letter for motorcycles. We require the full VIN, name and address. A Year of Manufacture letter will assist you with obtaining an age related registration from the DVLA - it cannot be used as proof of ownership.
There is a charge for this service of £30.00 we only can accept cheque or postal order in UK sterling made out to Honda UK and then posted to the following address:
