Bike tip-over Tip-over test fluid dozens of tip-over tests have been conducted on late model motorcycles by IAG. There is considerable variation between the amounts of damage to each motorcycle and there is also considerable variation between the costs of repairs. These variations are caused by specific features of design and by particular decisions made by designers and engineers in the pre-production phases of motorcycle development.

For the tip-over test program, each motorcycle chosen was an insurance total loss with cosmetic (non-structural) damage on one side only. The motorcycle was allowed to fall on its undamaged side from a stationary, vertical position.

The tip-over test results indicate that aftermarket motorcycle crash protection (“crash knobs”) can reduce the cost of repairs by as much as 40 percent. It was also found that the presence of pannier luggage can prevent a considerable amount of motorcycle damage. IAG found that naked motorcycles generally incur less damage than faired motorcycles, but it depends upon the quality of protection around the engine coolant radiator and the exhaust muffler.

IAG’s motorcycle research program was presented to the major Australian motorcycle importers on 17 November 2006, to co-incide with the Sydney Motorcycle Show. Representatives of Honda, Kawasaki, Suzuki and Yamaha witnessed several presentations and a live tip-over test.

Examples of motorcycles crashed.

  • BMW K1200LT
  • BMW R1200RT with and without panniers
  • Honda CBR1100XX Blackbird
  • Kawasaki ZX636 Ninja with and without crash knobs
  • Suzuki GS500
