Multiple injuries sustained in a motorcycle incident

AI-generated summary

A 67-year-old motorcyclist died from multiple injuries sustained in a head-on motorcycle collision when he veered into oncoming traffic while travelling at approximately 119 km/h. Police investigation revealed that his motorcycle was fitted with a Crampbuster throttle control device, which testing suggested could interfere with front brake application during emergency braking. The deceased was experienced, had ridden this route routinely for four years, and had adequate time to brake and avoid collision with the truck that prompted the maneuver. Toxicology was negative. The coroner's investigation identified a potential safety issue with the Crampbuster device affecting emergency braking capability, warranting further investigation into throttle device performance and promoting adoption of advanced braking systems such as ABS in motorcycles.
