Abstract

Recent trends in motorcycle sales have seen the move towards more racy designs. The heavier older models, with low riding fuel tanks, high handle bars and modest top speeds, are being replaced by lighter, faster more aerodynamic motorcycles with high riding fuel tanks and lowered handle bars, similar to racing machines. The high riding fuel tank is in direct contact with the lower abdomen and pelvis when in the normal prone riding position. In a direct collision, the fuel tank is driven back into the pelvis. In general, the accidents that cause these types of injuries are caused by sudden head-on collisions which occur without time to apply the breaks. The breaking systems in high performance motorcycles are capable of stopping the vehicle over a very short distance. When the breaks are applied, the front hydraulic shock absorbers compress, positioning the driver on top of, rather than behind the fuel tank. If the driver sustains a head-on collision in this position he will be thrown forward, avoiding contact with the fuel tank. If there is not adequate time to apply the breaks, the front of the motorcycle will not be compressed and the driver will be thrown directly forward against the high riding fuel tank, sustaining a direct blow to the anterior pelvis and soft tissues. The associated injuries can be devastating. Pelvic fractures, testicular rupture, urethral and bladder injuries, as well as other injuries may result from high velocity trauma. Another factor which contributes to the increased risk of injury associated with this type motorcycle is the racing position adopted by the driver. The driver is crouched in an aerodynamic position, gripping the dipped handlebars. In this position the driver does not have a good view of the road ahead. This is suitable for racing but is not ideal in road driving where dangers can come from all angles. This report highlights the impact that changing motorcycle design is having on the patterns of pelvic trauma. Faster, more powerful, aerodynamic machines may be suitable for racing purposes but they present a significant danger for road use.
