The unidentified man was hit late Tuesday afternoon as he rode his Harley Davidson north on Highway 97, between Oyama and Winfield, about 25 kilometres north of Kelowna.
Witnesses say the impact tossed the victim off his machine.
They say the rear, driver's side wheel of a Dodge pickup truck was flung into traffic and spun past the southbound truck before skipping into the oncoming lanes, ramming the motorcycle.
The 53-year-old Manitoba man driving the truck was not hurt.
Investigators say the truck tire had been replaced about a week earlier. (CKIZ, CKFR)
