Six MotoGP riders got the chance to try grand prix machinery from the past, during a motorshow event on the eve of this weekend's Dutch TT at Assen.

Jorge Lorenzo, Colin Edwards, Chris Vermeulen, Marco Melandri, Yuki Takahashi and Gabor Talmacsi took part in a demonstration ride on machines from the TT Museum.

Joint world championship leader Lorenzo was handed Jarno Saarinen's 250cc Yamaha, with fellow Yamaha rider Edwards given a 500cc machine which won at Assen with Jack Middelburg in 1980.

Vermeulen appeared on a 1976 500cc Suzuki used by Barry Sheene, with Melandri getting a 1968 Benelli replica. Scot Honda team-mates Takahashi and Talmacsi rode a 1976 Mike Hailwood Honda replica and a 1976 Bob McIntyre Honda respectively.

Assen is the only circuit from the original 1949 world championship still present on the grand prix calendar, although it has been heavily reduced and modified from its original 16.536km lap.

As is traditional, the Dutch TT will take place on the last Saturday in June, meaning free practice starts tomorrow (Thursday).
