One advantage of all the modern technology on bikes like the CBR 250 R is that it makes them easy to maintain. Bikes in days of yore needed constant attention to points, carbs, tappets, chains and so on.

The CBR 250 R has an oil filter, so it can go 5 or 6,000 km between oil changes. Use the recommended grade of oil.

Older bikes without an oil filter needed an oil change every 1-2,000 km, depending on how they are used.

The chain is a sealed O-ring type so it should be good for 30 - 40,000 km, and should not require much adjustment. Lubricate it with a little aerosol chain lubricant every now and again, but it should not require much cleaning unless conditions are very dusty or muddy. Watch what you clean it with, some solvents are not kind to the O-rings". Once the chain starts to "stretch" a little it is time to replace it, and the sprokets.

The standard chain on older bikes needs more frequent lubrication and adjustment. The "stretch" is actually wear in the links. On my bigger bikes in the past I seldom got more than about 15,000 km out of a chain, and would replace the sprockets every second chain.

The fuel injection and electronic ignition should require no attention.

Brake fluid should be changed every year or so. Brakes and tyres as required.

I should add that, being a farm boy, I have usually had access to a workshop and have done most of my own maintenance. It has become easier over the years as technology has improved.

Even if you do not do it yourself, it is a good idea to learn a bit, to know what to expect when you have your bike serviced.

Unfortunately there does not appear to be an English language service manual available yet for the CBR 250 R. Hopefully that will be remedied soon.
