Abstract |
Serious personal injuries have been reported, caused by motorcycles which suddenly began to wobble when ridden at moderate to high speed. A random sample of 1043 owners of 1978-1982 model year motorcycles was interviewed concerning their experience of wobbling in 1982. The response rate was 95%. Wobbling was reported by 45% of the owners, 8% reported at least one incident of severe wobbling. This figure indicates that about 6000 riders in Sweden experienced severe wobbling during 1982. Wobbling increased proportionately both with the distance ridden and engine displacement and was highest among those riders who make heavy use of the engine's power. A statistically significant difference in wobbling was found between Japanese and other manufacturers. The reported average speed where wobbling occurred was 118 km/hr. |
