Review

In 1997 a new model of the old model GS was launched in South Africa. Known as the R80GS Kalahari, it originates from the R80GS Basic available in Europe. It is white in colour with a blue frame.

The following is a description of what the motorcycle looks like: Round headlight with old instrument cluster as found on early model GS's and G/S's. Small windscreen. High front mudguard with Marzocchi front forks. White Power rear suspension. Early model 35 liter Paris Dakar petrol tank made of steel. No crashbars or sidestand. The rear subframe is the same as that of the first G/S's with the lugage rack at the back as an optional extra that bolt on. Paralever suspension. R80GS Kalahari decals. The old reliable 798cc aircooled boxer engine is used.

A short test by Bike SA (South African bikes magazine)
R80GS Kalahari (Lit: "Schwaeche" - -weakness-)

A story about a bunch of city slickers who were intriduced to the way of the Kalahari. And a bit about the R80GS, a modernised affordable progressive simple retro BMW. The name "Hari Kari" would have been more apt than "Kalahari" the way some of the guys bounced and hopped their way through the road test. The area was around the Kalahari Geinsbok Park, with our base the Motel Molopo at Andriesvale, also a stopover for the annual Easter Namib Desert Run. The bikes were the new BMW'S, named the "Kalahari" in South Africa, a revamp of the original late 1970'S R80GS into what it should have been in the first place. They took the legendary and reliable and tough and everlasting boxer two valve twin GS, first launched in 1978, and did to it what many had done to theirs at home - they changed the suspension and put on a bigger tank.

The best improvement was the suspension with the front end getting motocross type Marzocchi forks and the rear a White Power shock with Paralever drive shaft. This transforms the bike from a good road bike and an adequate offroader to a better of both. The bike can now hit potholes and ditches and objects of destruction without denting rims and sending shock waves to the rider. I have been riding BM's on the annual Easter Desert run for 16 years, each year bending the bike less and less as home made improvements to the suspension were made and suddenly in one hit BMW do it all with this Kalahari. Where were you, I asked, in all those years when 1 needed you.

I now also have a new R110OGS (no, don't phone, I'm not selling the old one) but it is heavier, albeit much more powerful, especially with the RS motor. And in low speed sandy conditions I'd rather have the lighter R80. Or, better still, this R80 with a 1000cc uprated motor, but we'Il probably have to wait another 18 years for that.

Other changes include a big Paris Dakar tank, which completely transforme the bike visually and makes it look the part, and wider wheels, with the new system where the spokes attach te the rim outside the tyre rim, allowing tubeless tyres to be used and making spoke adjusting possible without removing the tyre. The seat height, despite the better suspension, is actually lower, which is great news for those who paddle their way through sand and up cliffs and things.

On the first day we did the 170km of fairly straightforward hardish dirt road to Van Zylsrus and then 2OOkm along the Botswana border on the Molopo riverbed back to the hotel. It was an excellent route for testing the bikes, with a mixture of terrain. On the fast bit the speedo ran to 160km/hr, 15km/hr slower than on tar. And it required a longish stretch of hard road to get there, with sandy bits sending the rear into the famous BMW waggle and reducing speed. The "waggle" is what a BMW does at speed on dirt, and it involves mostly the rear wheel - it just does not follow the front but hops from side to side. This trait should be ignored by the rider. The bike, with its low engine mass, solid engineering and stable geometry, would stay upright and go mostly in the direction the rider intended it to go, safely and, believe it or not, accurately. Once the guys realised this, they became more relaxed and more confident with the throttle and lived with the waltz that gives an idescribably exhilarating high.

There were some F650's along and the comparisons were interesting. The F650 is a dffferent bike altogether, aimed at those who want a smaller, lighter bike. The 800 is bigger, more solid, more comfortable and more motorcycle. Off road the F650 is easier to handle, being lighter. It is especially better on sandy bends from where it can accelerate away faster while the 800 takes longer to get up to speed again. With agressive riding of both, there is not much dffference between the two. On the pans where the top layer crust was thin and breaking to make the going soft, the 650 was definately better, getting up and out of the softness better while the 800 was held back more. But neither are very good at negotiating soft desert or dune sand at low speeds.

On tar we did some interesting top gear roll-ons. We rode side by side and then wacked open the throttle from various speeds. From 60km/hr in top the 800 convincingly pulled away from the 650, from 80km/hr the difference was less and from 1OOkm/hr the roles were reversed and the 650 was quicker away and even quicker at 120.

Top speed was similar, with the speedos at around 180. With slipstreaming the one could pass the other only to be repassed as the other tucked into the slipstream and eased past. There was much of this (and other acts of hooliganism) going on during the 2OOkm trip from Andriesvale to the airport at Upington. BMW's two new Lifestyle Centres recruits - Colin Howell of Midrand and Gary Whitehouse of Durban were also there, and both happen to be seasoned enduro riders, as was Michel Lupini of Style magazine, which added spice to any dice. And surprise speedsters were Paul Shippey of Wiel and Ian Shrosbee of Topcar and, although with a lot less hooligan element in his riding, ex rally star Peter De Waal, now head of a department at BMW. He had become keen on biking a few months before on a tar excursion but by the end of this lot was worse hooked than a recently reborn happy clappy, and preached his enthusiasm to all and sundry. Lekker, Peter. We'Il see much more of you on the road or trail. Others there were, each deserving a mention, but none more than the late Barry Broady, the BMW motorcycle manager. We don't write obituaries in Bike SA, but all will miss the man plenty.

The R80 also did some heavy rock work, as seen in the photos. At the edge of one pan there was a sharp, rocky incline leading up to some picturesque cliffs. With much un-BMWlike footup observed trials riding (and thanks to Gary Whitehouses paddling with long legs) we got some bikes to the top. The torque is lovely and with momentum a BMW is a more than adequate trials bike.

Impact punctures on rocks are a problem with underinflated tyres though, as Michel (renamed 'Roeky") Lupini found out after getting one.
Falloffs were mostly of the slow, humorous variety and the fast stuff claimed only one casualty. After Colin Howell had spent many happy hours with the throttle cable stretched, a bend eventually did catch him out. It was an unexpectedlv sharp left hander after many-kilometres of fast sweeping bends. Colin did the usual rolling back of the throttle into the bend and rolled it on to power out of what he thought was a fast sweep. It was a sharp bend and he was a few gears too high and going several dozen kilometres an hour too fast. He broadsided across the road and flew into and over the opposite bank to record the fastest prang of the trip. The Iast time I looked he was still employed at BMW in Midrand so his episode was not among the firing category of misdeeds in the BMW code of conduct manual.

A really nice bike was almost everyone's conclusion. At R50000 it is affordable and the basic bike has proved its worth after 17 very successful years on the market. It is now upgraded in all the right places and should provide good on and off road ridin to owners for as long as they are likely to ride.
