I'd go the direction chris is. Convince them that your recon wasn't designed to handle the kind of riding you do, so it's only a matter of time before you break something major, and possibly get hurt when it happens. Suggest that if you would do something as simple as slip off the footpeg when you land, your rear tire would make minced meat out of your ankle because you can't get nerfs for a recon. Or if you ever landed a jump and had something in the suspension break, like the axle or a ball joint, it could be an over-the-handlebar experience like no other.
