The KTM 250 FRR parallel twin. July 26, 2005 Austrian motorcycle manufacturer KTM had one of the most remarkable debuts of any racing machine in history when it gave its new KTM Grand Prix 250 its first outing in the hands of Australian rider Anthony West at the British MotoGP round. The 250 class is highly competitive with any one of a dozen riders capable of winning on any day, and a machinery war between Honda and Aprilia that keeps improving the two-stroke breed, minute-by-minute, making it nigh-on-impossible for a new bike to break into the top echelon of 250 racing. So despite KTM’s illustrious off-road racing pedigree, and a fine showing from its recently created 125 roadracer, it was not expected to be competitive for some time yet, given that it had only been ridden ONCE prior to arriving at the Grand Prix. Then West had the new motor seize up in practice at over 200km/h. And then it rained, but West won an Australian dirt track title when he was 15 years old, and is comfortable with a bike sliding. What happened? The runaway leader of the race was Japanese wet weather specialist Hiroshi Aoyama until half race distance, but when Aoyama crashed, “Ant” suddenly found himself in a three way battle for the win. All three riders had near misses as the slippery surface and rain streamlets attempted to catch them out, with de Puniet looking the most likely to crash but eventually taking his first win of the season. In a dramatic final two laps, West fought out a tough duel against De Puniet who won the race by just 1.2 seconds with Stoner in third place. The result was the perfect debut for the new KTM 250 GP bike developed in Austria by the legendary two-stroke engineer Harald Bartol and his team.
