Posted By Stewart Ewing Riding motorbikes is a hazard in itself, but when coupled with severe vibration that results in parts of the body going knumb is even more of a concern. If anyone has studied the effects of,is aware of information that will help my data collation or is aware of equipment that can be borrowed to measure the output from vehicles this would be appreciated.

Posted By Paul Maddock Stewart, I really don't know where you've got your information from, but as a motorcyclist myself vibration is not even noticeable, especially to the extent that "results in parts of the body going knumb" I am also an acoustician, so delve into vibration occasionally, so please feel free to e-mail me with more details if you wish to discuss. ...oh, and one of my pet hates, "motorbikes are dangerous" - ROSPA determined that >60% of accidents are the fault of car drivers, and from personal experience I would agree. Those trying to drive while on the mobile/drinking coffee and applying make-up and having no regard to other road users are daily hazards. Motorcycling gives you a greater hazard appreciation and the application of roadcraft. There, better that I've got that off my chest :-)

Posted By Robert M Edwards Interesting question Stewart and one I dealt with in practice with a despatch rider who suffered 'White Finger' vibration on a particular model. I could not find anything really up to date but data nevertheless is available as follows; Stats on nature of injuries suffered by motor bike riders in accident cases. I can see the argument above about it being the car driver's fault but that is irrelevant in measuring the damage done to the rider. The results of accidents involving motorbikes are serious and fatal to the bike rider. A hollow victory for the rider who is not at fault! Have a look at http://www.bikedirect.net/RTA%20Statistics.htm for the stats in 1997 accidents. For the vibration issue have a look at the Japenese link below, I have attached the HTML version for ease of read. This has been about for a while and I applied the research to the despatch rider in London case. http://www.google.co.uk/...tion+data&hl=en&ie=UTF-8 The measurements are mainly on old bikes but may be of interest to you in how they were dealt with. Let me know how you get on with the data.

Posted By Laurie I have ridden a motorcycle since 1956. I suffer very badly from whitefinger, and started getting my first attacks in about '57. I have never worked in an industry where vibration is a factor. I had a bout of it today, outside temp about 15 deg (but I was not outside!), and I have not been out on the bike since the weekend. On the hottest summer's day, with lambswool gloves and heated grips, my hands can get dangerously numb before I've done fifty miles. In the winter (yes I ride in the winter too), sometimes it's only fifteen miles. It is a hazard, and it is real! Laurie

Posted By Keith Jackson I find the passionate referal to motor bikes interesting. The fact is the way traffic is nowadays it is dangerous to be on the road. Cars are designed with many features to make them safe and have the added protection a metal body encompassing the occupants. Motor bikes don't and can't have that protection. It is a well known fact that motor bikes attract young men who are risk takers so little wonder they have a bad reputation. I appreciate the fact that you can't tar all motor cyclists with the same brush but there's a good reason for them having greater hazard appreciation and that is because they are a greater hazard. An enjoyable way of travelling on a nice summers day though. Please take this in the spirit it's given, I like motor cyclists really.

Posted By Paul Maddock Keith, Agree - bikers tend to see motorcycling as more than a form of transport and a means of getting from A to B. Of course there are inherent dangers, but in the same vain, cars are sold with safety features as a prominent selling point, and I would feel a lot more comfortable making a high risk manoeuvre in a car than a bike because of this. This perception of safety leads many car drivers to take unnecessary risks. Similarly, being cocooned in a high quality helmet and leathers on a sunny day can have the same effect on a motorcyclist. Of course that has never applied to me M'lud! Because of the exposed nature of motorcycling I (try) to apply Police Road craft techniques and use the advantages of a bike (height advantage to see further ahead, and the obvious speed and manoeuvrability) to anticipate and avoid hazards. Each to their own, bikes aren't suitable for everyone, but I genuinely do wish that driving was taken more seriously - it's a privilege not a right! ...oh and speed does NOT kill - INAPPROPRIATE speed does. Authorities should do more to educate rather than enforce.
