== Overview ==
BMW G 650GS

Sertao


















BMW is adding a more off-road
oriented sister to their single-cylinder G650GS, named the G650GS Sertão.
Portuguese for wilderness, the Sertão uses the same 652 cc liquid-cooled
and counter-balanced single cylinder engine as the standard G650GS 
producing 48 hp at 6500 rpm and 44 ft-lbs of torque at 5000 rpm  but the
chassis and accessories have been updated to provide more off-road ability
without sacrificing on-road comfort.

The differences includes longer travel springs and wire spoke wheels. Up
front, the 41mm diameter forks now travel up to 8.3″ (up from 6.7″) with the
rear swingarm capable of the same (8.3″ up from 6.5″). The 19″ cast alloy
front rim has been replaced with a larger 21″ wire spoke rim with a narrower
rear wire rim, 3.00 x 17″, than the 3.50 x 17″ alloy on the standard G650GS.
The tubed tires are 90/90 R21 54S in front and 130/80 R17 65S in back.

The longer travel suspension gives the Sertão more ground clearance but also
higher seat heights. The standard seat is now up 2.4″ to 33.9″ with a 35.4″
bench as an option.

The Sertão comes in Aura white/Arroyo blue color scheme with prominent
Sertão lettering. Most of the engine and other components are painted
black with a few Nürburg silver elements such as the alternator and clutch
covers.

Several off-road ready accessories are standard on the Sertão including:
aluminum engine guard, high windscreen, hand protectors, and extended front
wheel mud guard. Dealer options include BMW Motorrad ABS which can be turned
off (likely standard in the U.S.), heated grips, Vario saddlebags, topcase,
tinted high windscreen, crash bars and the taller seat mentioned previously.


BMW G650GS Sertão  the sporty
BMW single cylinder enduro for offroad and everyday.

With its new BMW G650GS Sertão, BMW Motorrad has added a new, sporting
chapter to the history of single cylinders in the BMW GS family. Whereas the
G650GS thrilled riders with its lean, wiry offroad stature, the G650GS
Sertão promises even more sporting characteristics, even greater offroad
capabilities, and an even stronger desire for adventure. And all of this
without any sacrifice to the established virtues of a BMW single cylinder
endure such as everyday practicality, appealing price-performance ratio, and
playful riding properties.

Chassis for greater offroad practicality, optimized touring properties, and
dynamic design.

On the technical side, the new G650GS Sertão uses the established liquid
cooled, high-torque single cylinder engine of the G650GS with two overhead
camshafts, fuel injection, and double ignition. Its 652 cc displacement
delivers (48 hp) at 6500 rpm and a max torque of 60 Nm [44 ft-lbs] at 5000
rpm. Options include output reduction to 25 kW (34 hp) at 6500 rpm and 47 Nm
[35 ft-lbs] torque at 4500 rpm.

Whereas the G650GS chassis was developed primarily for country roads and
light offroad use, the Sertão presents far greater offroad practicality in
the form of longer spring travels and tighter tuning. In addition, it is
fitted with wire spoke wheels.

Also the new color concept underscores the dynamic character of the single
cylinder enduro.


The essential features of the
new BMW G650GS Sertão at a glance:

High-torque and low-consumption single cylinder engine with 652 cc
displacement. Max torque of 60 Nm [44 ft-lbs] at 5000 rpm and max output of
35 kW (48 hp) at 6500 rpm. Output reduction to 25 kW (34 hp) available.
Offroad chassis concept with long spring travels (front/rear 210 mm).
Wire spoke wheels with light alloy rims. Wheel sizes 21″ front and 17″ rear.
Dynamic color concept in Aura White / Arroyo Blue with Sertão lettering and
seat in black/grey.
Luggage carrier in black.
Extended top front wheel cover.
Two seat heights: 860 mm [33.9"] (standard) and 900 mm [35.4"] (special
accessory).
High windscreen.
Hand protectors.
Engine guard of aluminum.
Disengageable BMW Motorrad ABS (option ex works).
Extensive range of special accessories.


Sertão is Portuguese for
hinterlands or back country, particularly the arid badlands of northeastern
Brazil, the sort of place the new offroad-ready G 650 GS Sertão is designed
to explore.
From 2000-2010, the rock-hopping
variant of BMWs F 650 GS was called the Dakar, after the legendary rally
that ran from Europe to the capital of Senegal, honoring Richard Saincts
back-to-back wins on a BMW F 650 RR in 1999 and 2000. Security concerns in
Western Africa forced the cancellation of the Dakar in 2008; it was moved to
South America in 2009, where it has been run since. Although it now takes
place in a different hemisphere, the Dakar Rally has kept the same name and
Bedouin logo. Perhaps because KTM has dominated the past 11 Dakar rallies,
BMW opted for a new name for its taller, beefier G 650 GS while still giving
a nod to South America, where the 2012 GS Trophy competition will be held.
For several weeks last summer, I
had a crush on the G 650 GS, swooning over its light weight, nimble handling
and peppy, fuel-sipping 652cc single (Rider, November 2011).
Partial to adventure motorcycles with offroad prowess that matches their
styling, my heart throbbed again when the Sertão was unveiled. Its $800
premium over the base-model G 650 GS is money well-spent: spoked wheels and
more suspension travel for better bump absorption, and a rugged front fender
extension, taller windscreen, hand protectors and engine guard to defend
body and bike from harm and the elements.
After exploring muddy trails and
gnarly roads during the bitter-cold press launch, hosted by RawHyde
Adventures, we swapped our test bike for one shod with Metzeler Karoo
knobbies rather than the standard-issue, street-biased Tourances. Then I
blasted off on dual-sport rides, first in the Angeles National Forest with a
group from the local BMW dealership, then in the Mojave Desert, where my
buddies and I visited test-plane crash memorials
Compared to the regular G 650
GS, the Sertãos larger diameter front wheel (21 vs. 19 inches) and
different chassis geometry slows its steering somewhat. The Sertãos 8.3
inches of front/rear suspension travel (up 1.6/1.8 inches) lessens rake
(28.1 vs. 29.2 degrees), adds trail (4.8 vs. 4.5 inches) and extends the
wheelbsase (58.4 vs. 58.2 inches). The long-travel suspension soaks up bumps
very well without bottoming, though the only adjustment is rear preload. The
Sertão also has more ground clearance (9.5 inches laden) and a 2.4-inch
taller seat height (33.9 inches), though the seat-peg relationship is
unchanged so theres no additional legroom when seated. The seat has
supportive padding and a grippy surface. We didnt get a chance to test
them, but two accessory seats are available: a tall seat (35.4 inches) and a
single seat with lockable luggage compartment.
Though knobbies make things a
little squirmy, the Sertão is just as much fun on the street as its sibling.
A wide handlebar, skinny tires (90/90-21 front, 130/80-17 rear) and light
weight with a low center of gravity (fuel is stored under the seat) make it
easy to toss around. Those qualities also make it nimble off-road, where
line selection and last-second corrections are accomplished with ease. And
the big red button on the left handlebar simplifies turning off the ABS for
offroad riding. The liquid-cooled, fuel-injected single, good for 43
horsepower and 38 lbs/ft of torque at the chain-driven rear wheel, works hard
without complaint or excess vibration. The five-speed transmission shifts
cleanly, but I wished for a sixth gear at freeway speeds. Whereas the
light-action, cable-actuated clutchs lever is adjustable, oddly, the front
brakes lever is not. The single front disc brake provides sufficient
stopping power with good feel; using the rear brake helps, though the ABS
kicks in early.
Long stretches of stand-up
riding gave me a different perspective on the Sertão. Being 6-foot, 1-inch
tall, I had to lean forward and arch my back to reach the handlebar and work
the levers, which I rotated downward (Torx wrench required!). If the Sertão
was mine, Id add a set of adjustable bar risers to allow normal height on
the street and raised height on the trail. The narrow footpegs made the
arches of my feet ache when standing (even with the rubber inserts
installed, which I soon ditched for more grip), so Id swap them for wider
ones that pivot. Our test bike included the $300 Standard Package, which
adds heart-warming heated grips and a gear-powering 12V socket. Of course,
BMWs accessory catalog is overflowing with farkles.
During our test of the
base-model G 650 GS we averaged 57.3 mpg on regular unleaded, but for the
first 500 miles of the Sertão test we averaged just 49.2 mpg. Even taking
into account heavy throttle, heavier test riders and aggressive knobbies,
thats a huge difference. Leery of BMWs claim that the Sertão yields 74 mpg
at 55 mph, I filled the tank, rode 50 miles north on Highway 101 at 55 mph,
turned around and rode 50 miles back. And when I topped off again, it had
gotten 74.4 mpg! With knobbies! If you want to get 270-plus miles out of the
3.7-gallon tank, ride slowly.
The 2012 G 650 GS Sertão
continues BMWs lineage of adventure-oriented singles that goes back to the
1993 F 650 Funduro. Remarkably, the Sertãos $8,650 base price is just $50
more than the original F 650 Dakar, yet ABS is now standard. As a budget
Beemer, instrumentation is basic, with an analog speedo paired with an LCD
display (tach, dual tripmeter, odometer and clock). The hard-to-read
vertical bar tachometer ought to be a fuel gauge (a fuel tripmeter starts
when the low-fuel light comes on), and a go-anywhere bike like this should
have an ambient temperature gauge and a freeze-warning indicator. But the
bottom line is that cheers for the Sertão greatly outnumber jeers. It has
most of what you need, little of what you dont (especially excess weight)
and is more fun than watching the Puppy Bowl on Animal Planet. With a few
personalized modifications for offroad riding and some luggage, it would be
almost perfect. Hmmmwhat about a Sertão project bike and tackling the
Oregon Back Country Discovery Route
