U can make beats on a keyboard but unless it's really high quality the sounds r going to be weak. Plus it will take u much longer to sequence a beat on a keyboard than using software.

If want to get into beats go get Fruityloops and hook ur keyboard up to your comp using a midi connection. This way u'll use ur keyboard as a 'controller', where u can fool with the keys to come up wit melodies, but instead of using the sounds on your keyboard u can make it trigger sounds in fruityloops. once u have a decent melody, sequencing a basic drum pattern will be much easier in the software, not too mention saving the music as a wav or mp3.
