Vintage motorcycles from 1919 to 1930 prepare to take on the Kop Hill Climb 2013. From 1910 to 1925 Kop Hill, in the Chiltern Hills, UK, was one of the original homes of motorsport, where many of the world's leading drivers and riders of the time competed to be the fastest to the top. Now in its fifth year of revival, at the Kop Hill Climb 2013 an expected 16,000 people will watch more than 400 historic and iconic cars and motorcycles take to the hill once more, all in aid of charity. Saturday, 21 September 2013, Kop Hill, Princes Risborough, Buckinghamshire, United Kingdom.
