It depends. Coils are basically all just step up transformers, but they can be tailored to the type of ignition system. Best case is to get another coil to try. You could even try a cheap automotive coil from a junk car. If it works make sure you use some padding to install it, MX bikes shake a lot.
The second wire should be a ground. I forgot Suzuki's color code but you can figure out which wire is which with an ohm meter.
