The linked system is only on the abs models. It is easy to test. Put bike on centerstand. Make sure sidestand is up. Start bike. Put it in gear and let out clutch. rear wheel will spin. Pull in clutch and grab front brake lever. If it is linked it will stop or slow the rear wheel.
Now....
Turn off bike and have someone put weight on back, getting front wheel off ground. Now manually spin the front. Now depress the rear brake pedal. If you have linked brakes the front wheel will slow or stop.
You're almost correct. There is a proportioning valve (very easy to see on the ST's left front caliper. Merely pulling the brake lever, while the front tire is spinning in the air, will not activate the valve. The brake disc has to have enough force against it (like a tire slowing on pavement) to have the valve depress, which will then activate the rear brakes of the bike. You could also accomplish this by getting the front tire in the air, pulling the brake lever hard enough to stop the tire, then manually apply enough force against the tire/wheel (forcing it to turn) to see the proportioning valve push into the assembly. Then, your back tire will stop spinning.
