I'd say just give it a try, some parts can be really fun with its constant left and right bends. Once you get to the twisty parts there is really very little straightaways. Most of the action is around the middle portion of the route - the short uphill and downhill section before Semenyih Dam, and some more uphill and downhill after you take a left at the T-junction at Semenyih Dam.
You should be able to map it out on Google Maps, if not just shoot me a PM :top:
