The cb750 is the 1st bike I thought of after reading the post. I don't think the xr will be too much of an issue. I have not taken my clone ct70 forks apart and no issues. If anything the buyer has some leverage that high otd would be ridiculous on such technology. I wonder if the hawk, tbr7, raven, xpect have a lower bushing. I cant remember seal issues or excessive slop has ever been reported. Flex has been reported though. The forum gurus will figure out the xr150l. And I bet the forks will have flex complaints way before seal and wear issues. Wonder if flex contributes to wear. Or pinching the sliders with the 70s style axle.
