The Gear Study Paper: http://www.georgeinstitute.org/site...tit_2011.pdf
An Australian scientific study on the value of protective motorcycle clothing. One interesting finding is that not all protective clothing sold for motorcyclists actually does the job so buyer beware.
Worth reading - I found the study well-designed from a research perspective. The authors did a lot of homework and knew what they were doing.
It appears Australians are more safety-conscious than we in the US (although I have no data to back that up - just a gut feel considering what I have seen on the road).
According to the study, ÔÇ£Nearly all participants wore helmets (98.6% [86.3% wore a full-face helmet]), motorcycle jackets (82.5%) and motorcycle gloves (87.3%). Fewer wore motorcycle pants (34.9%), motorcycle boots (38.2%) or other heavy boots (25.9%). Body armour was worn over shoulders and elbows (71.7%), hands (50.9%), feet/ankles (29.7%), backs (18.9%), knees 9.9% and hips (7.6%). Almost half (45.8%) wore foam inserts in their jacket backs.ÔÇØ  added by me. With exception of helmets (in mandatory states) I donÔÇÖt believe American riders wear as much protective gear ÔÇô especially in hot weather.
Also noteworthy: 25.5% of the accident victims had a ÔÇ£learnerÔÇØ license (not exactly sure what that means) and 2.4% had no license.
In 60.3% of cases, the helmet sustained impact. Impact speed was <40 km/h (25 mph) in >57% of all cases - apparently mostly urban riding.
Table 2 shows quite impressively how protective clothing and body armor reduces injuries.
I know we can never influence the brand-X riders with 1/2 helmets, shorts and tee sirts, but maybe we can guide some new riders in the ATGATT philosophy.
Happy 4th of July, and ride safely!
