Can't say that I've ever felt that one wheel came off the ground. I'm also a very conservative driver so I've never tried to go around a corner as fast as I can.
Neither do I (
try to go as fast as I can)… and you shouldn't feel wheels lifting (
I haven't yet on my GL trike), and likely as not the front will slip (
I have felt this) before you turn it over from just going just too fast. To turn it over likely requires that you either hit something, something hit you, or you run off the road & down a bank, then maybe hit a tree or big love stone. My comment about lifting a wheel was more from memories of my tricycle, my first trike of sorts … as I turned it over a few times (
often trying to go as fast as I could … but a high center of gravity bit me a few times).
This is my second Roadsmith and my wife absolutely loves the ride for the passenger …
Oh yes, best to keep her happy. My wife likes riding the trike better than riding a bike too. Roadsmiths are nice trikes, I like them.
… and I never feel any bumps when the back wheel hits a manhole cover or pothole.
Oh, how would you know you hit them then?
I would recommend the heavy duty sway bar on a Roadsmith as I felt like I was being thrown off the bike on my GL1500 in the corners before I had it upgraded from the stock sway bar.
That feeling you felt is the trike leaning outwards, a trait of softly sprung IRS trikes. Tying the IRS's rear wheels together with fatter sway or "anti-roll" bars just makes the rear IRS behave more like SA as it reduces or eliminates lean ... but it does transmit more road feel to the seat of your britches.
If Champion is no longer making trikes it will be hard to get repair parts before long.
And then there is that … but really … most wear & service parts will not be too hard to come by. Like I did, owners will be well served to find out part numbers for brake & axle parts like bearings, seals, pads or shoes, wheel cylinders or calipers soon
before the information sources dry up.
