I Ride: 2015 30th anniversary ZX-6R
There was a factory recall on the stator, it didn't affect all '04 & '05, they have to be checked at the dealer to know for sure. Chances are it has been done, otherwise with the quoted mileage it probably would have fried itself. Otherwise CBR 1000RR engines are typically stout, with few lemons. The chassis has bailed many a kack-handed rider out from the abyss. These were never the fastest/quickest litre bikes, but with the right mods, it's the sportbike one could ride all day on. An R1/ZX10 are crazier rides, but the CBR won't do anything wrong, and will make you think that you're a better rider than you probably are.
There are tonnes of spares floating around the ether.net, and there are tonnes of nice aftermarket kit available. These bikes make a surprisingly good track bike, esp. for ones without a tonne of history on litre bikes for the very reason they don't misbehave unless an excess of bravado and a lack of intellect override its innate design brief.
In short, they are fabulous bikes, if not a bit too sane for some, but Christ, it's a litre bike with more ways to get into super fast trouble. It's the nature of the litre bike breed. If you are not overly mechanical, tell the seller that the sale is contingent on a clean bill of health from a professional mechanic of your choice. Any repairs (up to an agreed amount prior to inspection) would reflect the final price tag. You don't want to take the seller for a fleecing, yet you don't want to be on the hook for a shiny pile of merde. If the seller is not amenable to these pre-agreed upon terms then walk away. There are lots of other mature litre bikes on the market.
If you do in fact purchase the bike and you have additional questions, PM me. If I don't know the answer directly, I'll be able to send you to one who knows.
