I have some lech questions about top-level racing that I never seem to find the answers for. Sometimes the little stuff just gets overlooked! 1.1 never see elite racebikes with rotary steering stabilizers. Why is that? Are they inferior? 2. How often does a MotoGP crew replace the chain and sprockets on a bike? 3. Why is there a wristband around the front-brake reservoir? 4. How long will a MotoGP rider use the same leathers, boots, gloves and helmet if there is no crashing? Do they change often just to keep everything new-looking? 5. Lastly, why aren't there brakelights or mirrors as are used in F1 auto racing?
