Roberts crash was mechanical failure.
Sources have confirmed that Kenny Roberts Jr's exit from the Dutch TT was caused by machine failure, and not rider error.
Although initial reports suggested that the American points leader had simply locked up on the still wet circuit before being pitched headlong over the handlebars, video evidence has since pointed to an engine seizure as the most likely cause of the accident.

Although initial reports suggested that the American points leader had simply locked up on the still wet circuit before being pitched headlong over the handlebars, video evidence has since pointed to an engine seizure as the most likely cause of the accident.
According to motograndprix.com, race footage shows that the Suzuki's rear wheel fails to turn once Roberts' boot comes off the footpeg, suggesting that the engine has locked. This would not be the first time that the problem has afflicted the team - second rider Nobuatsu Aoki apparently succumbed to a similar failure at Donington in 1999 - but its revelation should restore Roberts' confidence in his own ability.
Largely uninjured, the American retains a reduced points lead, but will be back to defend his advantage at Donington in ten days' time.
