Hidden Valley Motor Sports Complex is located only ten kilometres from the centre of Darwin in the Northern Territory. The track was first constructed in 1986 and reinvigorated in 1998. A Motorcycling Australia (MA) licensed circuit, this track is known for high speeds and fast lap times. At 2.87 kilometres, featuring no fewer than 14 turns and one of the longest main straights in Australia at 1.1 kilometres in length, Hidden Valley is a popular circuit with riders and teams alike, offering modern facilities and amphitheatre style seating for race fans.
Overall, this is a fast and flowing circuit that requires a great amount of rider concentration, consistency and vigilance to be fast. The circuit places high demands the tyre and brake package of a bike. There is large potential for overtaking opportunity going into Turn One when bikes start to wash off the large amount of speed they carry off the straight.
The back of the circuit is where all the action happens. One of the biggest opportunities to overtake occurs in this section on the hairpin corner mid-track at the point. The circuit is very flat and ‘blind’ which means that track knowledge is paramount in aiding riders to achieve best their best lap times. Riders are on the edges of their tyre though the entire back section of the track and most of the overtaking happens under hard breaking.
The back section of the track could suit a bike with the low, bottom end torque advantageous for the fast exits out of corners. However, the larger bikes with more horsepower will have the upper hand down on the straight.
Rider fitness will also be a key aspect to success at this event with the extreme heat and humidity associated with the top-end of Australia, coupled with the fact that most riders and teams will be coming from the cold winter in the south to the heat of the north.
