Honda Rac­ing have con­firmed that the crash that ruled John Mcguin­ness out of the 2017 road rac­ing sea­son was caused by an un­ex­pected throt­tle blip.

Mcguin­ness suf­fered a badly bro­ken leg in the fast crash at Prim­rose Hill in prac­tice for this year’s North West 200, and while Honda con­firmed the 23-times TT win­ner had re­ported the throt­tle had stuck, or opened un­ex­pect­edly, it’s not un­til now the team have of­fi­cially re­vealed the cause.

“Hav­ing ex­tracted and reviewed the data from the ECU on John’s bike, we now know that a set­ting on the ECU race kit soft­ware re­sulted in the throt­tle blip­ping un­ex­pect­edly,” team boss Jonny Twel­ve­trees re­vealed.

“There was a long de­lay in get­ting the data from John’s bike due to the ECU be­ing dam­aged, and it had to be sent to the sup­plier in China to ex­tract the data from it. But we put in a coun­ter­mea­sure of a new spec of ECU for the TT to en­sure the prob­lem wouldn’t hap­pen again.

“Now we know what hap­pened, the race kit soft­ware has been up­dated and is per­form­ing per­fectly – there’s been no re­peat of the is­sue in over 5000km of test­ing and rac­ing since, in­clud­ing at the Slo­vakia Ring World En­durance race where the Blade was on the podium.”

Mcguin­ness broke his right tibia and fibu­lar in the crash and has un­der­gone nu­mer­ous surg­eries since as he con­tin­ues to re­cover.
