This type of bike started in the USA (can you tell) but is taking off here in Australia. Some of the quicker bikes in the US are running 6.9? @ over 200mph on street tyres. Here in Australia we have outlaw bikes running 7.5s @ 195mph. 600+hp bikes in the US are not uncommon in this class of racing. I reckon the are the best looking race bikes out there, i just thought id share these pics with you.
