    Just remember the longer you go with the swingarm the worse it handles. Unless you just want to build it pretty much strictly for drag racing or hill climbs. If you want to "ride it" I would spend that cash somewhere else. For the price of that swingarm you could have new plastics, tires, and pipes. But if you still want to extend it And are looking for the best deal or and or quality then i would wait until you're a full member of 3ww and buy from There. I've looked around myself and they're not cheap and not real common. But members here seem to have everything so I'm sure someone can hook you up.

    looks just like my buddie's 81 250r. he had different tires and a different after market muffler but otherwise looks identical. nice act by the way. i loved the early 250r machines.

    The popular for swap is 83-85 200x or 83-84 250r. 85-86R forks would require some fab work.
    You could also get trx300ex or 400ex rear hubs with different wheels and tires. That would help your stability in sliding corners.
