Davidson made some changes for the new 2007 models. I guess they
decided that size matters. The new 07 Road King, and most of its
cousins, sport a new 96 cu in. V-Twin, up from the 88 in. that
powered their baggers in the past. Plus they all have the new
6-speed tranny to get you down the road with more choices.
that all of the new touring bikes for 2007 are fuel injected (carbureted
models are not offered anymore) and with the new 96 cu. in. motors,
the Road King is quite a performer.
year they produced an 88 in. motor with 86 ft. lbs. at 3500. The
new 07 with the 96 cu. in. produces 92.6 ft. lbs. at 3500 rpm.
They never quote HP. They changed a lot of the lower end parts
for this upgrade. This includes crankshafts, connecting rods,
crank cases, transmission cases, and all the transmission parts
are new. Note, on the new models there are no
more external oil lines. When they introduced the 6-speed
transmission they moved the oil lines into the casing.
the most part, all of the top-end remains the same with the exception
of the fuel injectors. The Electronic Sequential Port Fuel Injection
(ESPFI) has been upgraded with the new 25-degree fuel-injector
nozzles (instead of 8-degree squirters). The addition of oxygen
sensors lets the Big Twin get away without catalytic converters
in the U.S. market, and new exhaust systems with redesigned mufflers
emit a burlier but still EPA-friendly bark. Yes, you can actually
hear the exhaust on a bike right off the showroom floor.
what I understand, because of the new
O2 sensors, there are no after market exhaust systems available
yet. Obviously, you can replace the mufflers to get the desired
effects you want. Plus the intake can be changed for better breathing.
Then you have to remap the fuel injection system.
new six-speed Cruise Drive transmission was first seen last year
in the totally revamped Dyna family. Although sixth gear isn't
a true overdrive, its 1:1 ratio reduces highway revs by 11% over
the previous tranny's fifth gear. In addition, the Cruise Drive
also includes some helical-cut gears that cut down on the whine
inherent in straight-cut gears.
a great, solid ride. How can you go wrong with a Road King? Yes,
it is a big bike and it does weigh a lot. It comes in around 730
pounds. But when you are riding down the road, it adds a lot of
stability and sense of purpose to the ride.
was a completely stock 2007 model with about 1,200 miles on it.
For being completely stock, I was impressed. That added midrange
torque seems a lot more than the stated increase on 7 ft. lbs.
You don’t crave on-ramps with this bike but it did perform
quite nice. To me the upgrade with the new 96 in. motor brings
it up to the old 88 in. with a stage one upgrade. I would love
to see what a little time spent upgrading this would do for the
performance. You know the saying; you can never have enough chrome
or enough horsepower. Having said that, if you buy a Road King,
you did not buy it for its straight-line performance.
heading north on Cave Creek from Buddy Stubbs, I was able to blend
into traffic with ease. The Road King is a very smooth running
bike. The only time you get any vibration is at the stoplight
or right after you start it up. When at idle the rubber mounted,
96 incher, vibrates like a washing machine out of balance. The
engine looks like it is going to vibrate right out of the frame.
This is normal. But the second you take of it is a smooth running
Harley. Smoother than the Dyna’s with the B motor.
spent about an hour
on the bike as I headed west on the 101 around to the 202
and back up 51 where I had to give it back to Buddy Stubbs. It
was about a fifty-mile loop and every minute on the bike reminded
me that I love to ride. What I really wanted to do is ride north
until I saw the sign; you are now entering Utah, and then east
to a sign that says you are entering Colorado and on and on. By
then, I am sure I would have heard from Jack at Buddy Stubbs.
on-ramp to the 101 had a stupid sequence light to phase cars onto
the beltway. No matter, after the light turned green, I was able
to twist the grip to the limit to a little past the legal limit.
It was refreshing, solid and smooth. The acceleration was good,
for me, I would have to have some engine work done, just to make
the time spent in the passing lane shorter.
running down the road was a dream. It was like riding on a magic
carpet with a windshield. I found that the 6th gear was really
tall. You should be going over 65 mph because high gear is so
tall. I would love to have known what the engine was taching when
you are going around 65 or 70. I did go as slow as 60 without
feeling that you are bogging the engine. You just do not want
to have to gun it at that RPM. A quick double downshift will cure
from the great ride and great bike, I am not sure what I can tell
you about this bike. As far as I am concerned, this is one of
the best Harley-Davidson motorcycles ever made. There are a lot
of Road Kings out there with a lot of miles on them. It is very
easy to see why this is one of the most popular Harley’s
has made a wise and great choice to upgrade the new Road Kings
with the 96 in V-Twin and new 6-speed tyranny. Except for idling,
the Road King is a very smooth tour bike. Has a lot of capacity
for carrying your toothbrush and hair brush so you can leave for
a couple months at a time. The Road King is one of the best looking
bikes on the road and after spending some time on it I can see
why it is one of the most popular bikes out there.
