The Honda Racing Corporation has confirmed a throttle cable malfunction caused Casey Stoner’s dramatic crash at the Suzuka 8 Hours.
The Japanese manufacturer has completed a thorough investigation of the incident caused by a stuck throttle, which left Stoner with a broken tibia and scapula.
Stoner was making his competitive motorcycle racing return at the prestigious endurance event, with the two-time MotoGP world champion leading the race for the Musashi Harc Pro Honda team before the crash.
Honda has since issued a statement apologising to the Australian, while confirming a new throttle system will be fitted to its machines for the remaining FIM Endurance World Championship rounds.
“Honda Racing Corporation has carried out a detailed analysis following the crash of Casey Stoner in last weekend’s Suzuka 8 Hour race,” read the statement.
“Checking the throttle, which is a particular specification for Endurance HRC Factory bikes, and different from the standard throttle used on the Honda CBR1000RR road version, a malfunction was discovered related to the throttle cable.
“This kind of problem hasn’t arisen before, however, HRC will cease using this throttle specification and will design a new one to be used for Endurance races.
“HRC would like to apologise to Casey Stoner and thank him for the effort he made in attending the Suzuka 8 Hour event.”
