I've got a line on a nice '90. It has a bit less than 50K miles. If purchased this would be my first big bike. I've been riding a VF500F for 20 plus years(it has 50K miles) and if I act on the '90 CBR it will probably be my last bike-I'm officially a senior citizen. I know Motorcyclist magazine had a piece in one of their fairly recent mags on the big CBR's and recall comments on front tire wear and some electrical(?) issues depending on year. What's forum member experience with problem areas? The mini-ceptor I'm riding has been as dependable as one could desire so I'm wondering how the big CBR stacks up for overall reliability. Thanks in advance for any guidance.

My CBR 1000 F -92 started to consume more oil than I liked at 107 000 km's, but apart from that everything worked perfectly and it didn't leave any visible smoke. I only owned the bike for a couple of months, so it may have been driven far more than the meter showed or been badly maintained. I know one CBR 1000 F's around here that has about 150 000 true km’s on the meter and still works great. Standard issues are cam tensioners and R/R-units. Sanding the backside of the R/R-unit and frame can prevent R/R-unit failures (heat is better dissipated to the frame). There is a separate thread on this issue.
The bike I know of with the most mileage is also a Honda, but a CB750 -72 with 500 000 km's on the meter. It still has the original owner and the engine and transmission has not been rebuilt, just got the normal wear-pieces replaced and serviced by the book.
I guess you can ride another 20 years on the '90 without big issues if you will service it per instructions and do the same mileage as with the VF500F

The biggest problem buying a used bike with that mileage is that it’s almost impossible to know how the bike has been treated even if it looks fine. It is important that the oil and filters have been changed when they should, and even more importantly, how it has been driven. In case it has been warmed up on choke and idle before running for several minutes or more, the cylinder walls will have been more flushed from protecting oil than if it is ridden almost directly. And if it has been runned hard before fully warmed up for minimum 10 km's or so, that is real bad. Some bikers have the bad habit to start the bike weekly or monthly during storage to listen to the engine and feel they lubricate the internals. This means that more and more water and sour contaminations will be condensed in the oil since the oil heats up very slowly to about 100 deg C when not runned, and that is what it takes to start boil out water from the oil. The oil can trap an incredible amount of water, maybe 25%, which is of no good for an engine and must be boiled out as quick as possible.
Another important issue is how far the bike normally has been driven each time, in case its 10 km's instead of 200 km's, the bike has been cold started 8000 times compared to 400 times, which makes a hughe difference concering wear. You can ask the seller about such things and possible get some clues. There are many bikes, even Hondas  , which have to be renovated before 50 k miles, while properly maintained and runned bikes easily will triple that number and still be in good condition. I’m sure you are aware of all this, but tell you just in case it could be of any help.

I'm assuming with that mileage in 10 months the reliability isn't an issue.
