You must have them aftermarket ones. Asyou wouldn't need to remove anything to install them. Now only seeing pictures of the after market ones I think I'd just lift te front end loosen upper and lower fork clamps on both sides lower the tubes far enough to insert the aftermarket tube style and slide the forks back up and into the mounts. Not sure if it could be done but I myself would probably try it with the wheel and fender in place. But if not I take them off and you can drop one side and then the other. Just thinking out loud here.
