just got my new drx 70 watercooled , let me tell you this is one nice ride , I've got 2 drx 50cc and they run so well I didn't think the 70 could perform much better... well i was wrong , made a couple of tweaks and this thing outruns my friends apex 90 ! by the way anyone looking for a good deal on an apex he wants to sell it now..he is going get a drx 90 this week. I just wanted to share this info for anyone condsidering the 70cc , give one a try!
