Nsr will cost between £1500 and £2800 depending on the miles, quality, speck etc...I´ve just paid £2400 for a 2001 model, de-restricted, sports tuned,arrow race can, immaculate condition with a fantastic repsol paint job and only 2700 dry miles on the clock. A good site is www.biketrader.co.uk. Good luck...The Rat.
P.S...De-restricted the Nsr will do 100mph....sports tuned 112mph.
