The truth is all the protective Darth Vader gear in the world won't save you in a collision - it's all intended to protect you in a high speed spill. And all that black stuff? Guess what happens while you are on black tarmac trying to get your bearings after failing to spot that diesel patch? That's right... you are invisible to the cars coming at you. The acceleration on a bike (or scooter I mean 125cc or above) is far far greater than any car. My 650 will go from zero to prison in about 6 seconds. Getting out of the way of the plonkers in tin cans is more about road positioning and good observation - dominate the lane, get a sixth sense about what that van driver will do, learn which makes of car tend to have drivers which show no respect to the lives of motorcyclists (Audi by the way).But by and large most people these days are very bike aware, and filtering through heavy traffic you willl find more car drivers very courteously moving aside to give you more room. Dont do it with a shiny new bike - it will get dented and scrathed up in no time at all. Wear a white helmet - best visbility gear you can buy without question. You can wear suits under bike gear - I do and it works well. Like all clothing you need to try various brands on for fit, and really you'll want either an all in one or trousers/jacket which zip together. Waterproof ideally or get a cajoule to go over the top. A top box is essential for carrying stuff and can usually take quite a bit of bike gear stowed away when off the bike. Biggest enemy is always cold - it really starts to wear you down quickly on a bike, and I have ridden sometimes and reached near hypothermia states (on overlanding riding) - gloves are obviously crucial but get some ski gloves in winter sod the protection. In summer - which conveniently is when tin drivers lose their manners because tempers flare in traffic and they start to get silly with it - wear the armoured gloves, handy for taking off the odd mirror when judiciously needed.If you want a 600+ bike I strongly recommend the parallel twins from Kawasaki - good power dellivery which is quite flat so great for town riding, take luggage, and narrow - great for filtering past or through traffic. And on the open road a well ridden one will suprise the sportsbikes...;)
