Model Evaluation
But while the basic design may be old, it’s not
primitive. Hydraulic lifters eliminate the need for
periodic valve adjustments, and improved hardware and manufacturing methods have continued
to keep the Evolution engine viable during the
past decade. Aside from the benefits of the aforementioned fuel injection, free-flowing cylinder
heads pirated from Harley-Davidson’s former performance subsidiary, Buell, combined with lighter
pistons and connecting rods, have extracted
by Scott Rousseau more power from the Evo. Reliability has also
been improved via additional cooling fins on the
cylinders and heads and an oil jet system that cools
the undersides of the piston crowns.
It had been a while since we last evaluated a
1200cc Sportster, but running the 72 through the
gears immediately reminded us of just how
much fun the venerable Evolution motor can be.
Punctuated by a thunderous exhaust note that’s

Brakes, Wheels & Tires
The 72’s patented “uniform expansion” non-floating rotors are
standard Sportster fare. Clamped by a two-piston floating front
caliper, its single 292.1mm front disc delivers excellent initial
bite and very good modulation without the wooden feel of some
of its Big Twin sisters. The same cannot be said for its singlepiston, 260.1mm rear brake, which lacks the good feel of the
front. But that didn’t prevent the 72 from consistently posting
excellent stopping distances from 60 mph during our braking
trials, including a best of 120.7'. Here again, chassis instability is
not a concern even under hard braking.
Bias-ply Dunlop whitewall tires and laced spoke wheels further
sell the ‘60s custom look, the 72 riding on an MH 90-21 (M/C
54H) mounted to a 2.15" x 21" rim up front and a 150/80-B16
(M/C 71H) on a 3.00" x 16" out back. They provide solid grip and
a consistent feel, although we have to wonder how long the
relatively narrow rear tire will last in light of the Sportster’s potent
torque output.

all of the engine vibration that used to make the Sportster
experience more akin to riding out an earthquake. On the
downside, the Sportster gained a lot of weight in the process.
For the sake of comparison, our 72 weighed in at 559.6 lbs.
with a full fuel load, compared to 529.0 lbs. for the 2000model XL1200 Sportster Sport, the last of the non rubbermount Sportsters we tested. Some Sportster aficionados
might think that the extra heft has taken some of the “sport”
out of the Sportster by giving it a heavier steering response,
but after riding the 72, we’d have to disagree.
With its 30.1° rake, 5.3" of trail and a 60.0" wheelbase, the
72 is pretty much on par with the rest of the Sportster family when it comes to numbers, but, crazy as it sounds, the
72’s 21" front wheel actually makes the Sportster feel more
light and precise through corners than some of the 19" front
wheel-shod models we’ve tested. The difference may lie in
the larger front hoop’s increased gyroscopic effect, which
increases steering stability when heeled over in a turn. Yet
the 72’s steering doesn’t feel heavy-handed in the least,
inspiring confidence in the twisties. As is the case with most
low-slung cruisers, its forward-mounted footpegs will scrape
tarmac before its front tire grip is compromised by steep
lean angles. It’s also nice to know that the 72’s chassis is rock
stable, even at triple-digit speeds. Despite its show bike custom
looks, this may be one of the finest-handling Sportsters we’ve
ever experienced.
But the 72’s suspension comes up short, literally, when it comes
to day-to-day traversing of well-traveled highways and byways.
There’s a price to be paid for that low-slung “digger” look, and
it comes due via the 72’s stubby, chrome, preload adjustable
Showa coil-over shocks, which offer a scant 2.12" of rear wheel
travel. While the rear suspension action is barely adequate on
smoother roads, freeway expansion joints quickly take their toll
on the rider’s spine, and the occasional pothole can be a gutwrenching experience. While loafing along during one of our test
rides, two different testers hit the same rough spot in the road
and bottomed out the rear end. The resulting shockwave through
the chassis was forceful enough to rotate the handlebars in their
clamps. As Harley’s customers continue to crave the low-slung
styling of its latest models, we suspect that the pain of restricted
rear suspension travel will be around for years to come.
On the other hand, the 72’s non-adjustable, 39mm Showa
conventional fork holds up its end of the deal just fine. Its 5.69"
of travel soaks up most of the road ripples encountered while
cruising, and its composure when cornering at higher speeds is
quite admirable. No complaints here.
Ergonomics & Attention To Detail
Mounted on 2" chrome risers, the 72’s 10" tall mini-ape handlebars offer a comfortable reach and a bend that doesn’t irritate
the wrists. But in this position, your arms will gather enough
windblast between them at freeway speeds to remind you that
this Sporty is best enjoyed at a more moderate pace. Its forwardmounted controls are well-placed. They’re not too cramped for
taller riders, nor do they leave short-legged ones stretching to
reach them. Perched just 28.25" from the ground, the Sportster’s
textured solo seat looks cool, and it isn’t as bad as you might
think, but it’s still the proverbial weakest link in the ergonomic
chain. More padding and/or a wider shape would be much appreciated even on shorter rides, although short rides are to be
expected on the 72 anyway. Averaging 43.3 mpg, it’s a Hog, but
it isn’t a gas hog. Even so, the Sportster 72’s 2.1-gal. “peanut” gastank will force you to seek out a gas station every 90 miles or so.
But that small tank is a key element in the Sportster 72’s looks,
and even the most ardent old-school custom freaks would be hard
pressed to find fault with its ‘60s-era persona. Its eye-popping
Hard Candy Big Red Flake paint job, accented by period-correct
pinstripes on its tank and fenders is exquisite, and the vibrant colors contrast nicely with the 72’s gray powdercoated engine, its
slashcut, 2-into-2, staggered shorty exhaust and its shimmering
chrome air cleaner and covers. The sleek look of its chopped rear
fender is complemented by Harley’s combined stop/turn taillight
assembly and swing-away, side-mounted license plate bracket.
The vibe is far out and groovy, even by Harley standards.
Final Thoughts
Coming into this evaluation, we were concerned that the Sportster 72 would represent style over substance, but we figured that
if its performance and comfort were half as good as its looks, it
would be tolerable. Surprise, the Sportster 72 met or exceeded our
expectations in every category but the one where we knew it
wouldn’t—rear suspension. Its engine performance and transmission are superb, it’s light-handling for a heavyweight cruiser,
and its ergonomics aren’t nearly as extreme as they appear to be.
Beyond that, the Sportster 72 nails the 1960s kustom kulture
vibe like no other production cruiser today, and it offers a whole
lot of cool for its $11,199 MSRP. Rear suspension woes aside, it
performs far better than any of the genuine old-school diggers and
choppers it seeks to emulate, and that’s just candy apple icing on
the 72’s metalflake cake.

TESTERS’ LOG
I don’t consider myself an old guy, but I can remember when
hard-core Harley riders treated Sportster riders as social lepers when it came to the hierarchy within the ranks of “the club.”
Of course, Harley certainly hasn’t forgotten the Sportster’s
ability to pull new members into its fold, and thanks to new
Sportster models such as the Nightster, the 48 and now the 72,
younger riders are flocking to the brand in droves.
One ride on the 72, and it isn’t hard to see why. Its excellent
fuel injection delivers kick-in-the-pants torque, its five-speed
transmission shifts smoothly and it handles far lighter than
its 560-lb. weight would suggest, making the 72 just as much
fun to rumble along the backroads as the boulevards. Its front
brake delivers excellent bite, allowing the Sportster to stop
shorter than some sportbikes, and its ergos are more comfortable than their radical looks imply. Of course, I’m smart enough
to know that my back won’t handle the 72’s squat rear end and
thin seat for too many miles, but the kids will love it!

When I first laid eyes on the Sportster 72, I worried that it
would have the same uncomfortable ergonomics, lousy ground
clearance, brutal ride and clumsy controls of its vintage inspirations. But I was very pleasantly surprised. Although the skinny
seat felt even narrower than it looked, and my back still hurts
from one particular dip in the road, its riding position is actually
rational; with an easy reach to the foot control and handlebars
that offer good control without tiring my arms. Even better, the
motor has excellent driveability and a great sound. In fact, it
actually seems to prefer a rapid pace, and 70 mph cruising felt
relaxed. The transmission is also very good, slick and quiet most
of the time—without the constant loud bolt-action “clack” that
had become an unofficial H-D trademark. But, saving the best for
last, what really blew me away was its handling…seriously, its
handling. Not only was the lean angle available before grinding the
peg feelers adequate, but with the pegs knocked back, you could
almost lay the sucker on its side, and it still stuck like glue.
Man, that’s totally cool!
