Around 200 bikers staged a rolling roadblock in south Cumbria in protest against proposed new EU rules on how they maintain their bikes.
The riders held up traffic for about half an hour as they rode in convoy at 40mph on the A590 and A65 near Kirby Lonsdale.
The Motorcycle Action Group (MAG), which organised the demonstration, has accused the European Commission of an 'assault' on bikers. It says the regulations would making biking more expensive, by making an ABS braking system compulsory and by forcing them to pay a professional for certain repairs and modifications.
The protest was one of several across the country in protest at the plans. The Commission says the draft proposals had been drawn up to improve safety and limit emissions.
But the Department for Transport has also raised concerns about the cost and timescale of the plans, and has suggested the UK should be allowed to retain control over rules on vehicles built by amateur enthusiasts.
