I've had three trikes, two were Yamaha Ventures and the third a VW conversion. The first was a Tri-Wing conversion with a solid axle. The front wheel would slide before the VW could even attempt a wheel lift. On the Tri-Wing trike two times I've lifted a wheel. The first was deliberate to see just how much effort it took to do it. That was in a parking lot going less than 25-30 mph. It took a very sharp hard 90* turn to lift the inside wheel. The second time was by surprise as I was going pretty good on a mountain road and drifted over the double yellow line, saw a car coming and jerked the front wheel hard to get back on my side of the line. Didn't realize I'd lifted the wheel till it squealed upon contact with the road again. Slowed a bit down after that LOL.
Other trike was a Hannigan conversion. It being wider and longer never had the slightest inclination to lift a wheel regardless of how hard I tried in a parking lot . A very stable platform that stuck like glue on the road.
No dumps on my part with any of the three but did get broad sided on the Tri-Wing conversion bya car. That did cause some cartwheeling of the trike then.
