Motorcycles

Last weekend I noticed a lot more motorcycle riders on our streets. We need to take the time to notice motorcycles and their limitations when we are driving full sized vehicles. Did you know the following:

This is a list of numbers of motorcycle deaths in U.S. by year from 1994 to 2010. United States motorcycle fatalities increased every year for 11 years since reaching a historic low of 2,116 fatalities in 1997, until a decline in 2009. In nine years motorcycle deaths more than doubled.

From 1980 motorcycle ownership among riders aged 40 and over increased dramatically, from 15.1 percent of all riders in 1980 to 43.7 percent in 1998. The mean engine displacement of the motorcycles involved in fatal crashes also increased, from an average engine size of 769 cc (46.9 cu in) in 1990, to 959 cc (58.5 cu in) in 2001, an increase of 24.7 percent. It has been suggested that the combination of older riders on higher-powered motorcycles might have been partially responsible for the increase in motorcycle deaths from the late 1990s until 2004.

Half of motorcycle fatalities in single vehicle crashes relate to problems negotiating a curve prior to a crash—almost 60 percent of motorcyclist fatalities in single-vehicle crashes occur at night.

In 2009 motorcycle fatalities in the US declined for the first time in 11 years. The yearly total dropped from 5,312 to 4,469. Automobile fatalities continued to decline for the seventh straight year. A decline in recreational motorcycling due to the late-2000s recession might account for the decrease in accidents, according to the authors of a report by the Governors Highway Safety Association (GHSA), but a state motorcyclists' rights organization, the Motorcycle Riders Foundation, said motorcycle use appeared to have increased, influenced by motorcycles' better fuel economy. A preliminary report by the GHSA estimated that the number of motorcyclist deaths in 2012 was more than 5,000, a 9% increase over 2011.

 Motorcycle riders need to have the following:

Items of Personal Protection Equipment


A full-face helmet credited for saving its user.

Half helmets or "skid lids" meet minimum legal requirements.
  • Helmet — A full-face helmet provides the most protection. Thirty-five percent of all crashes show major impact on the chin-bar area. However, 3/4- and 1/2-helmets also are available. Some motorcycle training sites have banned the use of half-helmets because of avoidable injuries sustained by riders wearing them.
  • Gloves — Commonly made of leather, cordura, or Kevlar, or some combination. Some include carbon fiber knuckle protection or other forms of rigid padding. Gloves designed specifically for motorcycle use have slightly curved fingers and the seams are on the outer surfaces to allow the motorcyclist to maintain his grip and control on the handlebars and clutch/brake levers. Some gloves also provide protection to the wrist.
  • Jackets — Generally made from leather, ballistic nylon, cordura, Kevlar or other synthetics. Most jackets include special padding on elbows, spine and shoulders. Airbag system technology is now available fitted to jackets and vests for accident protection and impact protection for both riders and pillions. Competition-approved hard armor is superior to soft padding. Competition-approved back and chest protectors can be worn underneath jackets. Inflatable airbag jackets can offer an additional airbag for neck support.
  • Pants — Made of the same material as jackets, usually including special protection for the knees and hips.
  • Boots — Especially those for sport riding, include reinforcement and plastic caps on the ankles, and toe area. Boots designed for cruiser-style riders often have steel-reinforced toes (However this reduces sensitivity of the foot when changing gear). Boots should always have a rubber sole (as opposed to leather or other less flexible materials). Despite their toughness and protection, most boots are very lightweight. Some even include titanium plating.
  • Goggles or Helmet Visor — Eye protection is of utmost importance - an insect or a kicked-up pebble in the eye at speed has enough momentum to cause significant damage. Such an event could easily cause the rider to lose control and crash. Besides this danger, squinting into the wind is unpleasant at best and watering eyes are quite distracting.
  • Ear plugs — Most riders experience substantial wind noise at speeds above 40 to 50 mph (64 to 80 km/h). Ear plugs help protect against hearing damage, and reduce fatigue during long rides.
  • Vests — Made with high-visibility colors and retroreflective materials, vests can be worn over jackets to increase the chance of being seen and allow drivers to better judge the speed and position of riders, especially in adverse conditions of dark and wet.
  • Other PPE — Dirt bike riders wear a range of plastic armor to protect against injury from falling and hitting other riders and bikes, running into track barriers, and being hit by flying debris kicked up by the tires of other riders' bikes. This type of armor typically covers the back, chest, and sometimes the extremities.
It is increasingly common for gloves, jackets, pants, and boots to be outfitted with hard plastics on probable contact areas in an effort to ensure that when a motorcyclist contacts the ground, his clothing will permit him to slide relatively easily as opposed to "crumpling", risking injury to body parts being stressed in abnormal directions.
Since the first line of protection in crash contact is the outer shell of clothing, designers have moved that further from the body. The ultimate protective shell so far is an airbag that stays with the driver as he flies off the bike. However, increasing use of "exoskeleton" plastic shields attached to clothing points toward design of a complete roll bar belted to the driver. A near-stage design is a plastic or light alloy double "wheel" perimeter rim around the driver, over his head and in front and behind him. When the driver unbelts himself and gets off the bike, he leaves the wheel roll bar with the bike. But when the driver flies off the bike, the roll bar flies with him and makes contact with hard surfaces. The driver is relatively safe from contact, belted within a contact rim extending out around him.
Riders sometimes use the acronyms MOTGMOTT and ATGATT, which stand for "Most Of The Gear Most Of The Time" and "All The Gear All The Time", when describing their personal gear preferences.
