May 12th 1951 saw the 2nd meeting held at the park and also the first appearance of Aberaman MCC current club president Herbie Davies riding his 350cc Royal Enfield. Herbie continued racing at the park until the end of the 1954 season and riding his 350cc BSA in the later years. Up until 2004 Herbie was the starter at the park. July 1951 saw the second meeting of the year.
In 1952 it all changed, the May meeting went ahead as normal but the August meeting was upgraded to National status, the feature race of the day being won by a young 18 year old called John Surtees.
Racing continued at Aberdare Park until 1964 with two meetings a year attracting some of the country's leading riders like Mike Hailwood, John Surtees, Bob McIntyre, Phil Read, John Cooper, Syd Barnett, Dan Shorey, Malcom Uphill, Ray Cowles, Ivor Lloyd and Selwyn Griffiths to name but a few. Then the Local authority carried out major alterations that heavily restricted the number of safe spectator areas available so racing was stopped.
It was during those early years at Aberdare Park that another record was set June 18th 1955 saw the first ever live television coverage of Motorcycling racing anywhere in the country.
In June 1978 racing resumed once again at Aberdare Park with spectators only allowed on the inside of the circuit. Still only a club event it attracted a very good class of riders, 1980 saw Aberdare once again being granted National status, 1982 saw the outright lap record of 45.2 sec held by John Cooper since 1964 go to Andy Hawkins in a time of 45 seconds.
In the final of the 1988 Welsh Open Carl Fogarty smashed the outright lap record to 42.5 seconds.
Aberdare Park is unique in that it is the only race circuit in Britain that is situated less than 1/2 mile from the Town centre. This picturesque and quite demanding 0.9 mile circuit winds its way through trees in the local town park and lies 30 miles north west of Cardiff.
The first ever meeting held here was way back on the 30th September 1950 attracting among others local riders M L Thomas from Aberdare and Eric Phillips from Aberaman. Despite being run in very poor weather conditions it still attracted a crowd of around 15,000 spectators.
Birmingham's Dave Bennett won the main race of the day and also the fastest lap of the day on his 500cc Norton at a race average speed of 49 mph.
