BMW R1100GS vs Honda XRV 750
You know the bit in African nature films where herds of wildebeest sweep
majestically across the plain and straight into a river where they either get
swept away or eaten alive by crocodiles? The Africa Twin has got sod-all to do
with that. It's got sod-all to do with anything except wide open spaces of tarmac.
Taking the Twin off road is asking for a hefty repair and/or medical bill. It's
too big, too heavy and its Michelins clag up at the first sniff of mucky-muck.
The road is where the Honda belongs, so that's where we kept it.
Which is a smart move because the Twin is a good road bike; not exciting the
way a Fireblade is, but a lot less demanding and usually a lot more fun. The
trouble with race reps is they're so damn serious...
The Africa Twin's 750cc V-twin was always going to be out-torqued by BMW's
1100cc gruntmeister, but how gutless the Honda is comes as a shock. 112mph and
52bhp is so pathetic we thought the engine was ill, but it sounded healthy and
top speed was bang on the 8,500rpm redline in top, so it wasn't. At
Bruntingthorpe, Mark F got the best quarter mile times by keeping the throttle wide open and
dipping the clutch to grab the next gear, proddy racing-style. It was still
horrendously slow.
The Africa Twin's lack of power isn't a problem on the road (you just ride
the thing flat out everywhere, all the time, to compensate), but the engine's lack of personality is deeply disappointing.
The power delivery is flat and lifeless with no bumps, steps or identifiable character to get your
teeth into. The motor is willing to work — it revs freely and quickly skims to
the redline in every gear — but from the polite chuffing at tickover to the
exhaust's apologetic whisper at full chat, the Twin feels dull and blunted. It
almost feels restricted. Mechanical noises and vibes are muffled into
submission, which is very comfortable and civilised, but boring. The Twin even —
get this — duffs away cleanly at any choke opening on cold mornings. How do
Honda do it when no one else can?
Should the Africa Twin owner ever need to pull a hooooge wheelie to impress a
burd or avoid running over the neighbour's cat, doing it off the throttle is a
no-no. The Twin needs a hefty dump of the clutch from a virtual standstill to
get the front up.
At least Honda's over-zealous civility department haven't completely
disguised the fact this is a V-twin; the bike still bops forward under full
throttle with the long-legged gait of a distance runner, and the seriously
understressed engine looks good for reliable high mileages. And a 112mph top
speed isn't all bad. The Honda is stable flat out but there's enough vagueness
in the steering to suggest any more mph would be unhealthy.
The Honda won't quite pull from nothing (it needs 2,800rpm, or 40mph in top,
before it'll take full throttle), but 70mph happens at a relaxing 5,200rpm, with
as much gumph as you'll find anywhere else in the rev range for top gear
overtaking. But dear oh dear: the gearbox is a mess. A gaping hole between
fourth and top, and a sloppy action make clean changes with MX boots a hit or miss jobbie. With road boots on it just hurts a lot.
The suspension is fully adjustable at the back and has air adjustable preload
at the front. I didn't fiddle — with so much suspension travel the ride is
always comfy and bumps happen miles away down below. With enough damping to take
care of the springs the Twin never gets wibbly-wobbly when you go mad; even some
last second braking and direction changes chasing BMW Road Captain Forsyth round
Cumbrian racetracks didn't upset the Honda. Or me.
The BMW is always a clear head in front of the Twin, but never leaves it
behind completely. When we realised how slow the Honda was at Bruntingthorpe, I
was surprised I kept up with Mark at all. 'I was flat out chasing you,' I said.
'I was flat out staying in front. Almost,' he replied.
This sort of throttle wrenching has a bad effect on fuel consumption. The fat
tank holds 23 litres of gas but doesn't keep a tight grip on it —130 miles full
to reserve was the worst; 160 miles the norm. At least there's over 30 miles in
reserve.
Tank shape and position mean the Twin handles dramtically differently between
full and empty fuel loads. As the tank drains you get used to a light and
fickable bike, you start chucking it about a bit, carving up cars and generally
looning around. Then, when you fill the tank up, the Twin becomes more unwieldy
than a fat man on a tightrope and the bastard topples over.
The Honda's brakes are F. strong. There's a lot of braking effect for little
lever travel, which is great for rolling up to traffic lights and howling the
front.
The Michelins are perfectly acceptable. Mark took one look and said, 'Ooooh,
I bet they're grippy.' I suspected sarcasm but, as my last encounter with an
African Twin ended up with a washed-out front end and some expensive-looking
cosmetic damage, I wimped out to make sure. The textbook riding technique with
these things is brake upright, off brakes, let front settle, then turn and get
on the power early. Stuff that. My preferred technique is slow in, slow out and
save the heroics for thems as can do it...

The Twin comes with a low level of equipment: the trick-looking LCD trip is
disappointing because there's not much to it. You get two trips, a countdown
trip, a clock and a timer. A few more functions, like average speed, ambient
temperature, humidity, latest stock market prices, etc, would be good.
In the live-with-it-every-day stakes the Africa Twin beats yer race rep
tackle hands down. It's easy to get on and just ride, day in day out, without
thinking very hard, or being intimidated into knee-scraping on every corner.
Neat touches to warm the cockles of your heart, and feet, include an exhaust
pipe which curls around your right foot to keep it warm, a wide seat and spacious riding position for lots of
arse shifting, a good fairing (which needs another 2in of screen to keep noise
and wind off six footers), and an impressive paint job if you're a visual
cripple. I am and I think it looks good.
So that's the Africa Twin: an utterly functional, competent, reliable, high
quality motorbike which, if you're in the market for a giant trailie, is better
than most and, if you're not, isn't worth a second glance. And to all those
people who thought a Honda 750cc V-twin would combine the cliche-pulling torque
of a Ducati with the reliability and build quality of the planet's largest
motorcycle manufacturer. To specials builders who reckon it'd be stonking in an
RGV frame — we say bollocks. It's not very good where it is.
People were very unkind about the R1100GS. The controversial styling and
peculiar choice of colours (pus yellow and off white) made people gag. And that,
if you've ever ridden one of these beasties, is a great shame; the R1100GS is a
whole heap better than it looks.
I've said some very unkind things about BMWs in the past but now it's word
eating time. This R1100GS took me by surprise. It's better than I ever expected.
The biggest shock is the size of the thing. With more than ten quids' worth
of unleaded on board, the prospect of a U-turn in a narrow lane is daunting.
With tip-toes on the tarmac, an unpredictable clutch action and the strange
side-to-side flywheel effect the odds are stacked against you. Overbalancing and
falling over is embarrassing and best avoided. When U-turn time comes it's much safer to get off and do it.
The next shock to the system is the gearbox. The usual wincing as first gear
crunches home is gone and replaced by a satisfying snick. The rest of the gears
go home with silent precision too. Amazing. A BMW gearbox that's smoother,
quieter and more precise than ninety per cent of Japanese gearboxes. What's
going on?
But the real surprise is speed. The R1100GS is blisteringly fast from A to
B. It's not powerful, it just grunts from low revs. Open the throttle at a
thousand revs and the BM's fuel injection responds immediately, punting the GS
forward instantly. It's the kind of lightning, shuddering response that sheds
the occasional unsuspecting passenger off the back. Crack the throttle open hard
in first gear and it'll loop over backwards; really, no lie.
On the road this low-down grunt is about as subtle as a smack in the face
with a cricket bat. Tight corners or slow left-right-left complexes are the GS'
home ground. Use the massively wide handlebars like a tiller, throw the bike
into the corner on the brakes, get off the brakes and wind open the throttle.
Shudder, shudder, grunt; before you know it you're out of the corner, hooking up
another gear and aiming for the next. It doesn't take much concentration to get
the best from it, making it the ideal longdistance scratcher.
But riding the GS quickly, really quickly, isn't that easy. It must be ridden how it wants, not how the rider
wants. This takes some getting used to — maybe two or three days, but once
you've cracked it everything happens second nature. Some of the quirks are
familiar, old BMW ones like the back end refusing to squat under power; but
there are some newer, more alarming habits.
That front suspension is responsible for 90 percent of the steering quirks.
Quite why BMW went to all the time and trouble of developing it defies belief.
The biggest shortfall of the Telelever front fork is its inability to dive on
the brakes. Dive under braking is a good thing in our book. Not only does it reduce the rake and trail of the steering geometry for
quicker steering (turn-in), but it concentrates the bike's weight onto the
contact patch of the front tyre. I had a couple of scary moments on the GS,
braking into slow downhill corners when, very suddenly, the ABS started working.
A squeal from the front tyre and a sudden loss of braking. Eek.
An R1100GS without ABS would be a dangerous thing in an emergency stop;
brake hard and feel the bike's weight act through a point level with the top of
the front wheel. Brake harder and feel the front tyre lock up momentarily, until
the ABS comes into play.
Snap the throttles shut and the forks dive; between gear changes is when it's
most noticeable. Accelerate hard and the front and back end rise upwards in
equal amounts; a very strange feeling if you're not used to this strangeness. I
only narrowly avoided several accidents while watching the forks go up and down through the hole in the fairing.
Captivating stuff. Our verdict? Sack the silly, just-for-the-sake-of-it fork
design and give us some USD teles (strong in the right places) instead.
Front and rear suspension work surprisingly well through corners. Throttle
position and treatment is critical but the big BM can cope with stutter bumps,
dips and hollows with amazing competence. Problems only arise when you have to
shut off suddenly mid-turn. This, due to the peculiar suspension reactions it
triggers and the excessive amount of engine braking, causes many a hilarious
moment.
Engine braking is probably more effective than using the brakes. Neither
front or rear brakes are particularly powerful. There's an incredible amount of
lever travel before anything happens. The front brake lever comes right back to
the handlebar if the stoppers are used hard. This makes four-fingered braking
the only option. Use one or two fingers and the rest get trapped between lever
and throttle.
But I'm getting carried away; all this talk of outright performance isn't
really what the GS is about. It's about covering huge distances quickly in
supreme comfort. Tank and seat allow you to travel the width of the country
without so much as a twinge from your butt or the need to keep stopping for
petrol all the time. Even the beaky looking fairing does a good job of keeping
wind-blast at bay. If you're under five foot six — forget it; the GS will get
the better of you at low speed. Taller riders will revel in the space available
and the generous distances between handlebar/footrests/seat. Spacious is not the
word.
The physical enormity of the GS is one of the best reasons not to take it off
road. Falling over at walking pace onto a rock would be expensive. It could also
be painful trying to right the bugger once it was on its side. Trail tyres seem
oddly out of place on a bike so inept at off-road work, but with a nineteen inch
front wheel and a seventeen inch rear, alternative tyres shouldn't be a problem.
The lockable, Q/D hard panniers are excellent, easily swallowing a full-face
helmet. They're reasonably waterproof too. Other practical touches are an
accurate fuel gauge (LCD) and a clock. Not sure about the benefits of a digital
gear indicator, though. Finish, be it paint, welding or detailing is the kind of
standard you'd expect from BMW. Detail freaks loved the straight-pull spokes and
wide alloy rims, techno freaks enjoyed grovelling around on the floor for a
better look at the oddball front suspension.
But for £8,460 (plus about £400 on the road charges) it's a lot of money. An
awful lot of money. Throw in a set of panniers (£360) and you've pushed the
price over £9k. However, next to a Harley Davidson it's still excellent value
for money. Take a test ride and see for yourself. Can't think of a better bike
to tour Europe on.
