You didn't say which model it was. but the page opened up at the Honda CX 500 Turbo.
500cc, across the frame, push-rod, Vee-twin.
Over here in England it was un-affectionally called the "Plastic Maggot", very popular with Dispatch Riders, but few else!
Reasonably reliable when new, but costly if there are problems with the alternator, or clutch!
The "Turbo" version was avoided at all cost, both by the riders....AND...the insurance companies...!!!
Any machine with the word "Turbo" is generally bad news, even by the Car Brigade...LOL...!
Still...!
If it was "FREE", then its something to sit on and pretend you are flying down Route 66 at 150 MPH...

...!
Dream-on...!
LOL...!
Cheers...!
