Yeah we're gonna have to agree to disagree on this one. The fact that Tilting motor works concept has independent suspension on the front two wheels makes it far better than a novelty item. So your stability gain point is a non sequitur. The builder even states that if you lose traction with one of the front wheels you maintain traction with the other one so your still back to at least TWO wheels on the ground with traction. If you lose traction in both front wheels then you've put yourself in a no-win situation which would not be helped by a 1 front 2 back configuration. A non-leaning trike scrubs the wheels when going thru ANY turn. Why would you want to lose traction like that? Even an independent suspended trike with the two wheels in back will STILL scrub a wheel when turning. My only concern with the Tilting motor works suspension was whether or not they upgraded the braking for the front.The only problem with the tilt is there is no advantages. it's just a standard motorcycle with a 3rd wheel. No stability gain no increase in front end traction very little brake gain. it's at best a novelty item for 12K and you get to buy 3 hard mc tires now.
A non-leaning trike will always be better and that's why no major company will or ever has build a leaner while they all have patents on the concept only for protection sake. HD and BRP for example have patents on leaners but will never build one as in time people will discover the advantage is zero.
Using the standard hand lever brake master does work well but some special other equipment is also required to make it work 100% a better option is to change out the standard 14mm master for a 17mm aftermarket which work exceedingly well
Since I have some trouble keeping a 900 lb motorcycle upright at slow speeds (1-2 mph) I'm considering the conversion. So for me it works just fine. For you...not so much.
