Well, I guess one grows accustomed to things and we don't even realize they are there.Chalo wrote:That's reassuring.

That's a big offset of the contact patch relative to the steering knuckle.
I also wonder (because the suspension is fully independent with no anti-sway) whether the trike rolls noticeably more to the outside when turning.
One side effect I noticed is that at higher speeds it takes more effort to turn the wheel so it kinda acts like a steering damper so keeps the trike centered a little better.
As for body roll:
Well, it has suspension so its obviously going to roll now regardless. I was expecting a boat, but I was pleasantly surprised to find this slow and progressive compression/roll to the outside like you would expect on a sporty car instead; and the way it feels now to me feels a lot more natural and way more predictable on the tight turns; mainly because I now have a sense of when the body starts to roll and how much as opposed to before where it was: no roll, keep turning... no roll, keep turning... no roll, keep turning.. OH SHIT.... and BAM it snap-flips on you and you're done. I would venture to say that a sway bar on a lightweight trike like this will make it feel really harsh, that is the big issue with sway bars on cars, you go too stiff and the thing doesn't roll but then you have oversteering (or understeering) all over the place and very hard ride over bumpy terrain. If anything, and before adding swabars, I would lower the spring rate a hair or two... and see how it handles. IMO with the current spring rates I don't think it needs any swaybars at all. Plus those extra 3 inches on each side really help on preventing flipping the trike.
All in all it is a great and worthy upgrade considering the constrains that were placed upon the designer. I know there is no replacement for a frame built with a long arm double wishbone etc... but between this and unsuspended I am going with this hands down, any day of the week. It is a huge improvement that its simply hard to describe unless you've been pounding the pavement @30 mph on an unsuspended trike for 1700 miles. Once you try this there is no going back IMO.
Now, I feel it really needs some dampening. On my way from work today I took my trike up to 50 mph and while it was a blast to ride and not feel the constant pounding, even on rough roads, you can tell there is nothing stopping those springs from bouncing all over when the pavement gets really rough, and the rebound dampening can be significant downfall on the stock spring setup b/c it can potentially bounce you back with as much force as it went in thus launching you into space... Specially so with low profile tires like I run on my trike (I run Schwalbe Tryker 20x1'5 on the front and I love those tires) with nothing to dampen the spring force.
Just my thoughts.
