==Definition==&lt;br /&gt;
The term &amp;quot;&amp;#039;&amp;#039;&amp;#039;Classic Racing&amp;#039;&amp;#039;&amp;#039;&amp;quot; in the [[United Kingdom]] is generally accepted as  racing as defined under the rules and or auspices of the [[Classic Racing Motorcycle Club]] (CRMC)[http://www.crmc.co.uk/]. This was established in 1981 and mostly caters for solos and sidecars manufactured in the period 1945-1972. &lt;br /&gt;
&lt;br /&gt;
Motorcycles from an earlier era, including a Pre-1935 class, are raced by the [[Vintage Motor Cycle Club]] (VMCC)[http://vmcc-racing.pchweb.co.uk/]. The VMCC race classes are mostly for Pre-1963 bikes.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Manx Grand Prix==&lt;br /&gt;
The [[Manx Grand Prix]], held on the [[Isle of Man]], is considered by Classic racers worldwide as the ultimate classic racing event.  This involves three or more laps around the famous 37 &amp;lt;math&amp;gt;3/4&amp;lt;/math&amp;gt; mile long &amp;#039;Mountain&amp;#039; circuit.  The Manx GP is traditionally held at the end of August.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Classic Racing worldwide==&lt;br /&gt;
&lt;br /&gt;
The International Historic Racing Organisation has been running for over 20 years and organises high level competition for classic racing motorcycles around Europe&lt;br /&gt;
&lt;br /&gt;
In the [[USA]] Classic Racing is organised by the [[American Historic Racing Motorcycle Association]] (AHRMA)[http://www.ahrma.org/] who organise Classic Racing events for all types of Classic bikes.&lt;br /&gt;
&lt;br /&gt;
[[Classic Racing Australia]] [http://www.postclassicracing.com/] is a non-profit organisation, formed in August 2000, which was designed to keep Classic Motorcycle Racing alive and well in Australia.&lt;br /&gt;
