I have just spoken to someone who is in the know. Apparently this "Association" is owned by a firm called Motorcycle Claims and they have ruffled more than a few feathers by offering sponsorship to organisations and then virtually take over the website or the domain name so that people are then directed to their Compensation claims website.
This also explains when I was asked to join the British Bikers Forum by an existing member and I mentioned who I worked for, I got a message telling me that there was a conflict because they are sponsored by Motorcycle Claims, although their was no mention at that time that the BBA is actually owned by Motorcycle Claims.
My contact spoke to the boss man, and apparently the boss man claimed that they have 9,000 members. My contact knows for a fact that this is an untruth.
So, in my opinion, not very credible.
