The start of a European Championship title race
Talk about a GoodTime! 

Awesome!

"Some commentators have likened this class of racing as the closest thing to Formula 1 without suspension!  This class uses a twin-cylinder Grand Prix bike motor producing up to 90 HP.  With an incredible power to weight ratio, these karts are capable of speeds upwards of 260 kph and can actually produce faster lap times than many V8 Touring Cars."   Victorian SuperKart Club

"Without question, SuperKarts are one of the most exciting forms of 4-wheeled motorsports available.  With competitors in the 250cc International class lapping Eastern Creek at times faster than Mick Doohan, and reaching speeds in excess of 250km/h (around 160 mph), it's easy to see why this has become one of Australia's most breathtaking sports."   RB Imports-Tuners, Australia

"On full sized racing circuits, the real maniacs can indulge themselves in the SuperKart class. With its liquid-cooled 250cc two-stroke engine and manual clutch six-speed gearbox, a SuperKart can deliver truly impressive performance (0-100km/h in well under 3.5 seconds, 240km/h top speed, 2.6g of cornering power.) SuperKarts cut some embarrassingly quick lap times and have been known to match the lap times of Formula Atlantic or Indy Light cars!! At two circuits in England, Oulton Park and Lydden Hill, the outright lap record is held by SuperKarts; faster than Formula 1 on these tight tracks." Capital City Kart Club, Vancouver, B.C., Canada

"Encouragement for me to do this test had been rare: a few days earlier at the Formula "A" Danish Championship Erik Magnussen (brother of the Stewart F1 driver Jan) told me that no vehicle had frightened him as much as the 250 kart which he had tried out.  I can well believe Coulthard when he says that a 250 kart brakes harder than a F3000." Vincent Caro, Karting Magazine, Jan. '98 on his test drive of Poul Petersen's 256 PVP SuperKart.

"Everything about this class reaks of professionalism, excitement, speed, money and sheer guts and courage!  With the use of exotic materials such as carbon fibre and minutely adjustable chassis, this class is of true international standards.  It is little surprise that some karts are worth upwards of $20,000."   Victorian SuperKart Club

"On a long track without its spoiler and wing the 250 kart would be as ill at ease as a skier without poles. I always knew these prominent accessories were not just there for show, but I had to drive the kart to verify and appreciate what they do."  Vincent Caro, Karting Magazine, Jan. '98

"The 250 International class SuperKarts, or Formula/E, represent the pinnacle of kart performance and technology.  This class is not for the inexperienced or faint-hearted, with considerable skill and driver experience needed to handle such a powerful unit safely and competitively.  Lap times at most Australian circuits are substantially lower than those of the top Group A Touring Cars.  This is definately not a budget racing class."   Australian SuperKart Home Page
