 For many years (circa 1947-1982), with the RAC, the ACU ran a motorcycling training scheme for motorcyclist road users, which was the precursor to the modern Compulsory Basic Training courses.For motorcycle racing, the ACU stipulates that a race competitor training course and a basic rider assessment must be passed before a Road Race Competition Licence is issued.The ACU also governs the safety standards for personal protection equipment worn during racing.
