It’ll have crap brakes, be uncomfortable, slow and due to its unreliability you’ll never ride it.
Unless you’ve cash to waste, don’t do it – and if you’ve cash to waste, just get yourself a decent m/c instead.
And the fact that none of the m/c’s pictured have number plates…
An R80 is going to be slow? Compared to a modern bike, but not compared to a cage, which is really the point. Plenty enough power to hustle along and zip past cars. Twin disks on my R100 pull up as quickly as anything I’ve ridden. Zero brake downs, 120 mile a day commute in winter, all over Europe, morocco, all over uk etc. My V50 had cracking handling, slow by modern standards, but more fun throwing it in than my Monster.
Really a load of shit what you’ve written, factually incorrect and you’re missing the point. For 30 years.
Come and have a crack on my R12 or my ZB31 and see if you don’t get off grinning from ear to ear.
