There are also clubs such as the Brit Iron Rebels that deny BA/Speedy membership. From their website:
Quote:
British Classic & Retro Styled Motorcycles Defined:
All new Triumph motorcycles that come under the 'classic' range except for the cruisers (Speedmaster, America and Rocket III)...
in this photo they are all British Motorcycles TRIUMPH Motorcycles so if some clubs wants to live in the past and can not keep up with the rest that is there loss
