Yeah it is a worry. I worry about my brother foreigneRS when I know he is out on his bike but if you love to ride as bikers do then it's not worth denying yourself. just put the energy you would use for worrying into intelligent riding, reading about safer riding, track practice etc. I bought a new blackbird when I passed my test but it's so powerful i respect it more than my gutless little R6 and concentrate on safe riding a lot harder on it.
