BMW's F650 GS Dakar tackles the rough with the smooth

The 2004 BMW F650 GS Dakar benefits from the same engine and styling updates as the rest of the Spandau single-cylinder stable, including the twin-spark head and BMS-C II engine management system with upgraded software and a considerably enhanced range of functions.

However, the off-road orientated Dakar retains the 21" front wheel and longer suspension travel of the previous Dakar variants, making it eminently suitable for the GS Challenge.

I'm sure the original idea behind the Challenge was focused on the big boxer-twin GS models but the Rotax-powered single is a considerably better bet for an amateur like me.

It's 25kg lighter than even the new, lighter R1200 GS, it's easier to ride on rough ground than the monstrous twins and the average rider has a far better chance of saving it if things get out of shape on the loose stuff.

Which is why I chose this model for the GS Challenge.

I wasn't ready for the flat-out road blast of getting to venue that came first; fortunately the Dakar is blessed with a higher screen than the standard GS, which kept most of the windstream off me at speed.

I don't know why – logic says the road version should have the higher screen since it is more likely to be ridden at highway speeds; the screens are nevertheless interchangeable so it is possible to mix-and-match all the body panels and create your own F650.

The screen is also attached to the headlight cowling, not the handlebars, so contributes greatly to the stability of the slim single – I was amused to note on the way back that my Dakar was less sensitive to gusty crosswinds than the quarter-ton R1150 GS Adventure I was following.

In the dirt the 21" front wheel made the bike more stable on a loose surface; it would track accurately on anything except thick sand - which was the downfall (literally!) of more riders than anything else.

The knobbly tyres a Dakar wears as standard issue help more on muddy terrain than the bone-dry, hard-baked routes of the GS Challenge but they certainly didn't hurt; I was, however, surprised by how well the mud-pluggers handled being thrown about on twisty tarred sections

I don't know how long they would last if used for that full-time, though; 600km of low flying put visible wear on the Dakar's Metzelers.

The long-travel suspension that is the Dakar model's main claim to fame is a mixed blessing; on really rough roads it's so much more comfortable than even the latest GS version that it's embarrassing.

I lent the Dakar to a GS rider and rode his bike over the 22km section from Paulpietersburg to Etomble and was struck by how much harsher the front suspension action on the GS was than that of the Dakar.

The difference at the back was less marked – possibly because the set-up was well pre-loaded with my 106kg!

Naturally the front end dives like a pelican under hard braking but you can make allowance for that – and the steepened head angle automatically makes the bike turn in just that much quicker!

There's a neat fork brace above the front wheel so the long fork stanchions don't walk; the bike is actually more stable on tar than it looks.

Comfort zone

Aside from the special Dakar colour schemes (there's the standard blue and white or a zebra-like white with black stripes) and the taller screen the furniture of the Dakar is the same as the GS.

The instruments are neat and simple (although the small LCD odo becomes unreadable when covered in a thick layer of dust), the switchgear is the standard Italian stuff so beloved of the Honda CEV and the seat is long, flat and deeply padded.

I spent 24 long, bumpy hours on it over three days and I could still walk afterwards, though a bit like an old cowpoke!

The F650 Dakar won't carry everything you need to get you from here to Cairo; for that you really do need a GS twin. But the Challenge showed me that it will handle the roughest day trips you can throw at it – and it's much easier to ride.

  • Thanks to Rob Barnes at BMW for the loan of the Dakar, which costs R68 500. We hope he the collar-bone he broke on the Challenge recovers quickly!
