Great thread, some of those old bikes were works of art. I made amateur on a Rickman, that had Montesa VR250 motor in it. Fast, sure, handle? Not so much.....we had Ossas, Montesas, Puchs, Hercules, DKWs, Monarchs, Maicos, Bultacos, CZs, Pentons, AJS, and more in our group back in the day.
Ah! The Day. I do have to admit though that I wish they had bikes back then as light as todays, and with as much suspension travel. Then again, maybe not. I am fast on the ground, not in the air, because I learned to go fast on the ground.
The worst bike I had.....Yamaha TT 500. I would break something off that damn bike every time I went out. Went through three kickstarters alone. And of course the kickstarter never broken unless I was way out in the backcountry and down in a valley. Funnest bike.....Honda Elsinor 125.
