I bought my CBF250 new in March 2006. Since then I've covered a little over 26000 miles, at an overall average of 94 miles per gallon. A tankful is usually good for over 300 miles.
Although generally regarded as a commuter bike it's quite feasible to go any distance on it as long as you're patient. I've had holidays in France, Scotland and the Isle of Man without a moment's trouble. You have to bear in mind it's designed as a city bike when planning overtaking, but the key is in the word 'planning'. Do it carefully and you'll pass all the bigger bikes while they're queuing for their next tankful of fuel.
Since fitting a Scottoiler my chains last a bit longer than 6000 miles, which is also the mileage I get from rear tyre. Front tyres last about 13000. I've tried Pirelli (good grip), Continental (longer lasting but not so grippy) and I've currently got a set of Bridgestones fitted.
The bike is still on the original battery, disc pads and rear brake linings and the only faults have been a seized ignition lock (replaced under warranty), a snapped speedo cable, and a faulty dipswitch which was successfully cleaned rather than having to be replaced.
The headlight is acceptable on main beam but the dipped beam is so poor that you're left wondering where the road is after dipping for oncoming traffic. Brakes are fully up to the performance, but I've fitted a braided hose on the front for extra peace of mind.
It's a most forgiving little bike, easy to handle, economical and great fun on B roads. Motorways are not its natural habitat, but even so it'll cope with a steady 70mph in lane 1 away from the faster traffic hogging the centre lane.
I ride all year round, and the finish has suffered considerably as a result. Engine case lacquer is bubbling, fastenings have rusted and the exhaust pipe is heavily corroded. The bike is evidently built down to a price and this is evident in the poor quality of the finish and the fact that a centre stand (essential in my opinion) is an optional extra. I had the Honda flyscreen fitted from new but that was a waste of money as it didn't make any difference to the wind pressure at any speed. A larger Givi screen has proven more successful. To Honda's credit, they've done a good job of the instruments, with a clock and fuel gauge incorporated into the dash.
Apart from the gripes about the finish I'm delighted with this motorcycle, and if Honda would fit a stainless steel exhaust (and ideally a silencer that made it sound more like a motorbike and less like a washing machine) and use thicker paint it wouldn't be far off perfect for a civilized user-friendly 250. I came to it from a series of bigger bikes, and if you choose you routes it's still possible to have a lot of enjoyment without spending a small fortune on tyres and fuel.
Overall, a competent little motorcycle.
