How much can you lower a ktm 300 mxc?

You are only limited to an inch or so because the KTM's have a linkless suspention in the rear. The only thing you can do is make the rear end soft so it sags way more than it should, then move the fork tubes up in the tripples till the front fender hits the frame. If you do this your bike will ride like crap and you will not like it.
