An MEP is urging riders to sign a petition against EU measures to make motorcycles impossible to modify.
The petition, proposed by UKIP MEP Marta Andreasen, calls on Government, MPs and MEPs ‘to oppose in the strongest terms this proposed legislation’.
If more than 100,000 signatures are gained, parliament will have to consider a debate on the issue.
Tuning will become impossible and even home-maintenance severely hampered under plans.
So-called onboard diagnostic systems on new bikes could detect non-standard parts and trigger a warning light until the 'fault' is rectified by a dealer. Routine faults could be reported in code decipherable only be a dealer, preventing home-servicing.
Andreasen said: "My position on this is clear: I want to see this needless legislation thrown on the scrap heap. It is actually an unwarranted attack on biking culture and a way of life."
