On the 1200 RT Twin Spark, it means 2 plugs per cylinder. In other words 4 plugs total.
The term is often somewhat abused whereas "wasted spark" (plug firing on every stroke) is also referred to as twin spark. BMW uses this setup as well to save on components.

Hi Anonymous, on a twin cam make sure you are leaving both spark plugs in head while checking for spark. The usual suspects are:
1. Fouled spark plugs.
2..Battery voltage below 9 volts, loose or broken battery cables.
3. Loose wire connection at coil, or plug between ignition sensor and module.
4. Spark plug cables in bad condition and shorting or leaking, spark plug cable connections loose,or cables connected to wrong cylinders.
5. Ignition timing incorrect due to faulty ignition coil, ignition module, CKP, CMP, MAP, or BAS sensor
