I have to say, I have modified my trikes in a lot of ways. Most of
the modifications had to do with simplifying the set up. My kmx X
classes are set up similar to the ST. I like the st but I am more
comfortable with the angle of the X class (less laid back) whe I
ride the KMX, I do so with others in an urban setting. these are
fun trikes to race in short sprints as well as taking corners at
higher speeds. I encourage that that do the latter to lean into the
corner relevant to the speed you are going. I have been able to go
up on two wheels as in the videos and have even gotten it to stand
on one wheel (I have the scars to prove it)

KMX, as in all trikes are great for what they are meant for and
there is no other that will do it as well. If you want a virtual
bullet proof trike, get the KMX. They are the best for short term
rentals. I have set up in a park setting, renting to the masses
(unlike a bike shop that gets one or two at a time) i HAVE RENTED
15 AT A time with others waiting. the KMX is quickly adjusted to
fit the majority and simple to use for most. If you get interest in
your area and want a summer income, this type of business is great.

the lack of front derailleur and hence the lack of gears. The X is
the standard model shall we say, and the RT is the touring model.
The only differences between X and Xt are the wheels, the X having
smaller diameter rims and the fat tyres, the RT being larger
diameter and having skinny lighter weight tyres.

with it, it's possibly slightly heavier than the newer ones, and the
seat design has I think changed a tiny bit. The longest ride on it
so far is just over 100 miles in a day - I should say it absolutely
killed me, but that wasn't the trike's fault, more the poorly-tuned
engine with the slight aero-belly.

Apple fat tyres, they're about the same size but the Maxxis tyres
are designed to be bomb-proof (no bad thing) but they are
consequently a fair weight, the Schwables are lighter and di make
the trike feel lighter too. Rolling resistance o both is good, don't
be lulled into the trap that fat-tyres = high rolling resistance,
the Maxxis tyres can be pumped up to 100psi at the front and 60+ psi
at the back and at those pressures you're down into equal rolling
resistance with a skinny tyre. The Big Apples run at lower pressures
but were designed to give a very low rolling resistance.

that you can actually have a decent ride on all three. I think if I
were in the market for a KMX now, In your position I might be
tempted by the ST, anf fit it with Big Apples. Then if you find you
do want the extra range of gears you could always ask your brother
what he's got lying round the shop to upgrade the gearset (you can't
tell me he hasn't got a "spares" box) no doubt you'll be able to get
trade price at the minimum. The one downside to this is the
magwheels of course. If you buy spoked wheels and then decide you
want to run different size rims, I would have thought the brother in
the trade could have built you up wheels as you want them on your X-
Class hubs. If you buy the ST, you'll have to buy hubs, spokes, rims
and everything should you wish to upgrade.

> So the summing up of all that. It's your choice really. I'd ask
your brother about the various spec options and also ask him about
speccing a KMX to suit you. It might well be that the base is the ST
and he can build you up something really special. Then again if he's
in thr trade who knows perhaps he could even order a bare frame and
steering assembly and really, really build you something unique and
special.
