The Wolf and John pointed out, do lean into the curves. This wil reduce the feeling you are being pushed to the outside of the curve. Also helps to push down on the outside footpeg - that will also help counteract the push away from the inside of the curve. Also it uses your leg to keep you upright instead of arms, mid and upper body muscles. Helps make it easier to steer. Wolf suggested taking a curve out & in. They teach that in the MSF riding classes. It is not only smoother line, you can also see further through a curve, so it's safer. Technical term is a "late apex". Generally good riding techneque on 2 or 3 wheels.
The MSF also taught "Slow, Look, Lean and Roll" to go through a curve.
We don't lean, but slow slightly, look through the curve then power through. As john mentioned, use both arms - push and pull. If I have the backrest on, I also use that to push against. Again, not using the body muscles as much.
hdrider axes:Once you get the hang of it do you feel you can stay with or outperform a good rider on 2 wheels? Yep. A good trike pilot can keep up with most of the riders out there. I was going down the Pig Trail (locally famous for it's curves) to camp at a rally, and I kept having to brake in the curves for a pair of sportbikes ahead of me. They'd pull away on the straights, I would catch up on the twisties. They were dragging pegs, not hanging off on the turns. (I would guess good riders, not racers) They weren't too happy I was keeping up with their race replicas.
They were even more surprised when we stopped and saw I was pulling the Bunkhouse camper. I've always been able to keep up with cruisers and touring bikes.
Sometimes a bit slower from a stop becouse of the extra weight, but right there wanting to pass in short order.
