Honda cb 750 1981 is this a good deal?

Long story short, I'm getting my first motorcycle. I know very little about bikes. I'm looking at a honda cb 750 1981. It looks in pretty good shape. (nice paint, little dings, clean and no leaks)

it has 23,000 miles

what is a good price for this type of bike? Any things to look out for?

Added (1). It runs BTW and sounds good

Added (2). update:

they are asking for $1000
here are a few picture /var/folders/1p/9_lb607d7x31794jcl2tnx3h…

$1.00 a cc plus $100.00 for running, decent tires at begiining of riding season. So top of $850.00. Not current registered/running? - but complete, not frozen engine then $.50 a cc for $375.00. Stored a long time means a carb clean job and wiring check- not expensive but long time labor means high shop bill if taken to shop. Get manual and do the work yourself means time but less $$ and it is a good learning project. 1981 Honda 750 means minimal pollution control, no computers and still have parts available-- not as good part situation for even older Harley but a lot of 750 Hondas were sold and there are really no unknown things that can go wrong with it- everything that could go wrong has gone wrong sometime and the fix is known on internet and experience Honda mechanics knowledge. Minor problem is the possible use of ethanol fuels - that can mess up carbs but likely ethanol safe parts are available. My 1978 gold wing had carbs rebuilt with ethanol safe needle and seat, floats- problem was fuel pump had no newer replacement like a 1982 would have had- direct replacement with 1988 fuel pump that was ethanol safe. Just under $1000.00 for runner that can do 100 mph easily even if old beats spending $5000.00 for small crotch rocket.

It's a good deal if the price is right, but bear in mind that it's an air cooled engine that will overheat unless you keep the bike moving, so waiting in queues or at traffic lights for a long period will sustain engine damage on today's congested roads. This was not a problem in 1981 with reduced traffic.
So, if you don't have the confidence to filter due to inexperience, I would opt for a water cooled bike and the over engineered Honda VFR750 would be good for you especially since it never needs cam belt adjustment as it has gear driven cams.
The VFR would also leave the CB750 for dust if you want to with a top speed of 150mph. Although, it's just as happy to toodle long at the national speed limit.
I own one with 49,000 miles on the clock and it still purs like a kitten.
Just think about it.

It's a good idea to pay a Honda mc mechanic to give it a good going over. He / she should look for head play, wheel bearing play or resistance, front / rear wheel alignment, swing arm side play. Tire wear, chain / sprocket wear, pull and load test the battery and check for corrosion, check the charging voltage output of the alternator, block up the bike and hand upshift and downshift through all of the gears, check the engine's compression and leakdown, and review the bike's service history including when the front forks, rear shock(s), and carbs were rebuilt. A bike that old could need all new fuel lines, just from the age of the bike. Check 'em for flexibility and cracking.

Like dude, I used to own a 750-four, and it was very top-heavy. I hated it. I wouldn't want one even if it was free. It's a terrible choice for a first bike. Go smaller and newer.

It's to old of a bike.
Parts are difficult to find because of it's age.
Parts are becoming scarcer by the day.

As a total beginner I would stay away from the 1981 bike.

So what are your personal skills? Can you re-upholster the seat? Change the old tires out for safe new tires? Fix deteriorating wiring and charging system? Change out a old battery for a new one on a motorcycle. What tools do you have? Expect to renew every brake line, brake cylinder, every gas line, and carb part! How is your financial situation?

If you had a motorbike history, you wanted the bike, and could do your own work you could convert it to a café racer… If that's what you wanted… Why anyone would use a 2 x 4 for a motorcycle seat is a total mystery to me unless they only used it for a 1/4 mile ride to the closest bar. But that's a worst case use… I would keep it stock regardless of the latest motorcycle craze!

That takes a lot of time and money… And you have to know what you are doing… New brakes, tires, rims, seat, paint… Big money!

With less than 650 miles use per year on average, it has clearly spent a long time sitting unused and probably unloved - that is always bad news.

It's too old

Many good answers, but my word of wisdom (45+ years of MC ownership!) is to find something in the 400-500 cc MAX range for a beginner bike. That would be a lower power (less likely to get away from you) and lighter frame. (much easier to balance and push around.) As far as the age? My favorite bike is my 78 Suzuki GS 400 that I've had for the last dozen years. Even with my level of experience, it is a good and very practical bike. It is heavy enough to handle highways, powerful enough to cruise long distances (mine is full dress and still runs with the "big boys") and much easier on the pocketbook for fuel usage. At the end of a long touring day, I'm nowhere as worn out as I used to be when touring on my Norton 750 Combat Commando.

It is an older bike, but if you learn how to maintain your own, they can last forever. (I overhauled mine, including new clutch, brakes, chain et al when I bought it just to be safe and have since put more than 20k miles on it with zero problems.) Good running can turn to not running very quickly as riding styles vary and motorcycle engines are not as forgiving as car engines when you run them differently than the way they have been treated their entire life.

Worst thing for a bike is to sit. Fork seals go. Tires age. Tanks rust. Unless a very experienced friend OK's it, stay away unless you want to spend a couple years chasing down parts and coating fuel tanks.

Age isn't necessarily a factor, its miles and make. Harleys, you can get anything for.

ref: Have an 83, bought with only 3,000 on her 5 years ago. Had to invest a lot. Still needs paint, seat cover, shocks/motor mounts, carb base seals, Again!
