James, You talk about the pros and cons of ABS on bikes. Your research relating to ABS experiences on cars is relevant, I believe, however I think that there is at least one major difference. Stopping distances on surfaces such as gravel have shown to have been increased for ABS-equipped cars. This is due to a gravel dam being built up in front of the wheels of non-ABS cars, when its wheels are locked. This situation cannot apply to bikes, for lockup is much more serious on a bike than a car.
Most riders can t do that on non-ABS bikes.
