Metric Measurements. 12.5"x9.5" open. You'll be in serious trouble if you need to depend on the kit that came with your bike. Not only is the tool grade grossly inadequate, but content lacking. We can fix that with the potent M1, which contains the exclusive PowerDrive wrenches and loads of other high-quality tools and roadside items. All packed in a durable double-panel, zip-up polyester pouch.
