Young American John “Hopper” Hopkins tested today at Estoril, Portugal, riding a Red Bull Yamaha YZR500. It is the third test with the team for Hopkins, from Ramona, California.

Hopkins took to the track around 10:00 a.m. and rode until lunch. Shortly after the lunch break, Hopkins lowsided a YZR500 and slid into a gravel trap.

Hopkins was unhurt while the racebike suffered minor damage.

The crash ended Hopkins’ testing and he is expected to arrive back in the United States on Tuesday.

The team is negotiating with Hopkins for the 2002-2004 World Championship Grand Prix seasons.
