Knockhill's twenty-fifth anniversary week ends with the Fife circuit hosting latest rounds of the Scottish Regal 600 Motorcycle Championships this weekend, just seven days after the razzmatazz of the Auto Trader British Touring Car Championship.

While reigning champion Sandy Christie, from Dunfermline, competes in his first race of the year having decided after watching the opening rounds that his decision to retire had been premature, tomorrow's meeting highlights the strengths which have seen Knockhill expand and grow into one of Britain's busiest tracks.

Ironically, the 1.3-mile circuit held various motorcycle and rallycross meetings before it hosted its first four-wheel race on May 18, 1975. While Eddie Labinjoh was first to take the chequered flag in his Alfa Romeo 2000GTV, a link with the present was also competing.

George Franchitti, father of Bathgate's Champ Car ace Dario and Formula Ford star Marino, also donned the overalls and crash helmet to race on the opening day. Seventeen years later in 1992, Knockhill hosted the BTCC for the first time, and the event marked the circuit's acceptance into the higher echelon of UK tracks.

The circuit is poised for further expansion and will receive a #200,000 grant from the National Lottery through sportscotland.

Work is expected to start in the close season in an effort to attract the British GT and Formula 3 Championships as well as the National Saloon series next year.
