Yep your right tc a mate of mine has a chopper and after riding it around for about an hour it was starting to get a little uncomfortable ,but still nice to have one to ride locally.
My Rocket after letting Lushie loose on it
my ol Laverda 180 crank Jota 1000
my ol Kawka Z1 900 with it's 980 hi comp Yoshi kit
my ol Yammy RD 350 with it's Expansion Chambers (just for a bit of fun)
my ol Yammy DT 250 ported and polished with a 30 mm mikuni and Whispering Smith exhaust (mild Expansion-Chamber) just for a bit of dirt fun
and if I could have one more ....
My first bike a 1968 Ducati 250 single (cranky little thing but great little ripper when it's electrics weren't playing up)
Then there was....... no I won't go on
I just wish I never sold any of my bikes I have had except maybe the Yammy 750 triple, it was not a good bike...very disapointing for a Yamaha
as far as road worthy they are like are rockets some say they r bad some say there good flip a coin depending on the set up they can be good to ride 200 miles but thats about it they are for local travel in my opion but still would like one for local things
