The Sevenoaks & District Motor Club are running another event London's Crystal Palace.
Ticket price is shown as £10 per adult per day according to the website.
Sprint racing returned to the Palace back in 1997, and back then, the Sevenoaks & District Motor Club were kind enough to have motorcycles competing too, but alas, we're no longer invited, so (alas) its a four-wheeled-only event.......
Here's their website

Motorsport at the Palace returns next year for its fifth consecutive running, with the popular London sprint taking place on Sunday 25th and Monday 26th May 2014.
Reinforcing its status as a community-focused event, Motorsport at the Palace has now raised over £13,500 for local charities. Next year we hope to lift the bar even higher, as London’s leading motorsport event returns to thrill spectators and drivers in equal measure.
As usual, there will be plenty to keep guests of all ages entertained away from the track. The show area will be packed with exotica, with numerous single marque, classic car and motorcycle club stands, in addition to retail and catering areas.
Younger guests can enjoy fairground rides and inflatables, while those on the look-out for a new car can browse the on-site Ancaster showroom, featuring Ancaster’s extensive range of Nissan, Fiat, Alfa Romeo and Hyundai vehicles.
And as always, the friendly paddock will be open to visitors, enabling guests to get up close to the cars and chat to the drivers before they take to the track.
So get ready for another fantastic couple of days of motorsport in one of the capital’s most pleasant and welcoming parks, and help us celebrate the unique motorsport heritage of Crystal Palace – ‘London’s Own Circuit’.
