No offence intended, very very few cyclists die in incidents not involving other vehicles, overwhelmingly they're hit by other vehicles. Many motorcyclists die without intervention from other vehicles, and those where another car is involved excessive speed is often a significant contributory factor. Yes SMIDSYs occur far too often, but there's often shared blame.
It is by far the riskiest mode of transport on the road, and as Chris says the first sunny day certainly sees a colossal reduction in the average skill level. There's a NSL A-road near me I was on yesterday, dead straight, Roman Road. I was doing about 55, in a queue of traffic. A motorcyclist came from at least 5 cars back, doing (I would guess) 80mph+, over a blind crest, he seemed surprised when the back end twitched slightly, and even more surprised by the oncoming traffic he clearly hadn't anticipated.
New sports bikes are far far too capable given the minimal training required to own one. Even if you are the best rider in the world, if you're utilising even 10% of your R1s capability you're asking for trouble.
