HE'S young, keen on bikes and fast. Cai Youren, 13, of Downend School near Bristol is a sprint motorcyclist who clocked up 16.16 seconds from a standing start for a quarter mile on an 80cc bike.

His grandfather Phil Baines has now built him a Kawasaki MX125cc for the new season. The racing machine is designed with a hand-operated quick-shift gear button to slice off fractions of a second during acceleration.

Sprint racing is similar to car drag racing, with machines racing against the clock. The next meeting is in April at Keevil in Wiltshire. See www.sprint.org.uk.
