Increasingly motorcyclists are choosing protective equipment constructed of man-made materials rather than leather due to their improved weather protection, from heat, cold and water, and the increased utility these garments tend to provide in terms of pockets and vents. In all cases it is important to get the correct fit when purchasing riding gear. Incorrectly fitted garments may result in excessive injury if armour shifts out of position during a riding mishap. Safety : Motorcycle road casualties fell by almost 60% between the early 1980's and 2000, improving on the government target for road casualty reduction of 40% over the same period. Motorcycling is as popular now as it was 20 years ago, but rider casualties for every mile travelled are 30% lower compared to the early 1980's. Research proves that other road users are primarily at fault for around 60% of all bike crashes.
