Introduced by the legendary Geoff Duke, here are two nostalgic films that demonstrate the ferocious riding talent of US riders Steve Baker and Freddie Spencer.

'Formula 750 Champion' follows Baker through his 1978 European GP road racing campaign as he competes in the fastest class of the day. As one of the first Americans to take part in the Grand Prix series, there was no room for error. This skilled Works Yamaha racer manoeuvred his way with precision through a very eventful season battling against Suzuki rider Barry Sheene and charting a dozen crashes on the way!

'Spa' brings all the drama from the 1982 Belgium GP, where 'Fast' Freddie Spencer celebrated Independence Day in style thanks to an incredible 500cc victory. As one of the most dangerous and spectacular racing circuits in Europe, massive crowds gathered to marvel at the world's best motorcycle aces as they took on a truly testing track! The film also takes a look at some great sidecar action from Spa, and there's footage from the 250cc class.

Featuring interviews with big names like Kenny Roberts, Barry Sheene, Graham Crosby, Giacomo Agostini and many more, this is a nostalgic glimpse into life in the paddock and on the racetrack from a memorable era of motorsport.

With exotic mutli-cylinder machines reaching speeds of 180 mph, American Challenge brings you two wheel action at its most refined!
