The
TRX 700XX has plenty of power to lift
up the front end, yet the power is very
controllable and not over aggressive
|
For those die-hard Honda fans that held out for
the release of the TRX 700XX, they won’t
be disappointed because the 686cc engine provides
plenty of power in stock form, and it really shines
in the mid to top end rpm range. The TRX700 possesses
ample power to bring the front end up with a quick
stab of the throttle to easily clear rocks, logs,
or any obstacles, but at the same time the 700XX
has a very gradual power curve on the low end
and is very controllable thanks to the Keihin
PGM-FI 44mm throttle-body fuel injection system,
but don’t let the smoothness fool you. The
top end power on the TRX 700XX seems to be limitless,
and it easily the fastest stock sport ATV that
I have ever ridden. In wide open areas, the machine
just kept pulling and pulling on the top end and
had enough power to be able to handle the huge
500ft + dunes on the ride even without paddle
tires, where as some of the other sport quads
at the riding area appeared to be struggling to
climb some of the larger dunes.

| After
several high speed runs through the desert
valley, I came to the conclusion that
the TRX 700XX feels like the fastest stock
sport ATV that I have ever ridden, and
the only machine that might be as fast
is the new Arctic Cat Thunder Cat 1000
Utility ATV, but unfortunately we don't
have any conclusive data to verify the
top speed of the 700XX at this time to
compare it to other ATVs |
The addition of fuel injection on the TRX 700XX
was a smart move by Honda because it will be
make huge difference for consumers that live
in mountainous areas because it can easily adapt
to evaluation changes without any need for re-jetting.
Also, fuel injection also allows for easier
performance tuning when buyers decide to add-on
performance upgrades to the TRX 700XX.
We also believe that Honda has used the programmability
of the fuel injection system to de-tune TRX700
because it is a little sluggish on the bottom
end and it also had a tendency to stall fairly
easily at low RPMs, but sluggishness disappears
at mid throttle when the 686cc engine comes alive.
Honda didn’t have any comments on our findings,
but we are confident that re-mapping the EFI to
richen the fuel mixture will eliminate our test
units low end hesitation, which was probably done
to meet emission standards. We do feel this this
engine has plenty of potential to turn the 700XX
into a fire breathing beast.

| One
great benefit of EFI on a big bore ATV
like the TRX 700XX is how easy it is on
the thumb compared to one with a carbureted
fuel system |
Honda
also upgraded the exhaust canister to
stainless steel, so it will hold up to
years of riding with out rusting away
over time |
