Listen guys,i live in South Africa and i own a '99 kdx 200 (modified to the max) but 2 stroke oil prices are a bit hefty now and are climbing.I am interested in buying a 4 stroke that can match or beat my kdx package.i am particularly looking at a used klx 300....could you please let me in on the pros and cons of the bike and how it will compare to my kdx.what does the 'R' mean in 'klx 300 r'? please guys,it would be much appreciated! thanks
