Direct access is only available to riders aged 21 yrs and older, passing your test on a machine producing 46.6BHP or more (typically a 500cc or larger, we use 650cc motorcycles) allows you to ride any size of machine once you have passed your test. Restricted access means you have sat your test on a 125cc motorcycle, this would restrict you to a machine having a power output, which does not exceed 33BHP, restrictor kits can be fitted to machines with a more powerful output. This restriction lasts for a 2-year period, at the end of the restriction period any size machine can be ridden. Restricted access is popular for those under 21, or those who lack the physical attributes to ride a larger machine, or for those who do not wish to have access to a large powerful machine straight away.
