whenever I saw anyone try to modify the xr 200..it seemed to loose that "whatever xr 200's had" that made them so much fun...bigger forks .. lost the magic steering, more power? not much worth talking about was ever gained, expensive shocker
..meh...no real difference... you should be able to find another swing arm and weld a bit of pipe in there to see how it behaves.
I watched one of the chapmans flog an xr around the ol tin mine special test at the foster "devils pinch"enduro in 84...man he held the xr flat and just bashed thru the gears to slow or speed up ( I always maintain he pulled the top of the carb it revved so hard). was a great sight and sound- unforgettable.
