Much cheaper than your average bike, probably around 125cc running costs. I do around 8k per year, and so far I'm getting around 82 mpg imperial. I expect a minor service to be just under 100 GBP (every 8k) and I'm guessing a major (every 16k) to be around 200 GBP. Honda dealer prices. This is much cheaper and much less frequent than your average middleweight bike. One of the reasons I bought one of these. Hope this helps.
dont forget tires. You will go through them much more often than on a car. I dont know about the CBR specifically but many bikes want new tires every 3000 or so miles. If you are going to do 10k you may need tires 3 times a year. Terrain and riding style obviously influence this greatly. If you tear out of your home on a cold day expect to go through tires faster than if you let them warm up a bit before you ride aggressively.
You will also want to be good about changing the oil (oil + filters), cleaning the chain (cleaner + lube), maybe oiling the clutch cable (pennies literally), and other related stuff.
