Interestingly enough - i have written a paper for Uni on lower limb injury occurences, causes and possible preventative measures of motorcyclists.
During the research i uncovered some surprising stuff - like the amount of bikers who DON'T wear protective gear, and that manufacturers have been told for YEARS they need to improve the protection available on the motorcycle around the lower limb area - but they just arent listening. Money seems more important than safety.
I have quite a few research papers on motorcycle accidents, injuries etc and TONS of stats - its all part of my work for my uni course - if anyone wants to read any lol, then just PM me.
