To boldly go where no man has gone before; Captain James Kirk said it years ago and now exploration, wilderness and adventure are limited only by what you can carry in a set of panniers.

The adventure category is one of the most popular to which the modern-day motorcyclist aspires. It’s growing at an unprecedented rate and BMW is one of the leaders. It’s no secret that the GS range continues to impress riders all over the world, myself included. Like many other riders, it has only been the last few years that I’ve discovered what an incredible way it is to see the world. From remote deserts and mountain passes to inner cities, the adventure segment can nearly do it all. Unlocking further possibilities is only an R 1250 GS Adventure away.

It’s the newest kingpin of the BMW adventure range, and is one of the first bikes that comes to mind when “hard-core adventure” is mentioned. The new higher-tier R 1250 GS Adventure continues the trend set by a long line of hugely capable predecessors, right back to the first R 80 GS released in 1980.

The previous R 1200 was a proven beast, so BMW didn’t need to go back to the drawing board with the new 1250’s key features. Instead, small but significant improvements were made to the current and already enormously capable GS structure.

Things like the ergonomics, riding position and weight distribution remain more or less unchanged, making sitting on the bike and lifting it off its side stand a very familiar and confident experience. There’s still plenty of room on the bike, even for a taller rider like myself, so it retains its trademark globetrotting comfort.

Thumb the starter and accelerate away and the increase in capacity is immediately obvious. The 1250 got hit with a substantial 14 percent boost in rear-wheel output, which sees power raised from 92kW (123hp) to 100kW (134hp), as well as an 18Nm torque increase.

Even more impressive is the fact that peak power and torque both chime in below the 8000rpm mark. The boxer engine has always been relatively low-revving, linear in its power curve and totally predictable, and the 1250 is still exactly that.

Those power figures might not seem incredible to die-hard road riding fans – especially from a bike that tips the scales at a quarter of a tonne fully fuelled. But I can assure you, just rolling on the throttle in second gear produces diesel-like torque, more than enough to power-wheelie off into the sunset. It’s happy power, the really usable kind.

But what impressed me the most about this engine is the technology behind how it makes that power. It’s not a simple case of adding a few extra cubes and tweaking the bore and stroke; the new boxer engine employs variable valve technology that BMW has called ShiftCam. And from a firm that has been developing and producing variable valve technology on its passenger and performance cars for almost two decades, it’s about time it tasked its engineers with the job on what is its most popular engine platform to date. Though BMW remains adamant the system – which is the first time variable timing has appeared on a BMW motorcycle – owes nothing to its four-wheel counterparts.

It’s an innovative set-up, too, one that those with an interest in new tech will love. Controlling only the inlet valves, the inlet camshaft of each cylinder incorporates two different cam profiles mounted side-by-side on the same shaft. One is a partial-load cam, the other a full-load cam and, depending on rpm, gear and throttle input, delivers a perfectly suited output in the most economical way possible.

So as you ask more with your right hand, an electronic actuator lifts a pin that locks into the camshaft, and then the rotation of the shaft allows the pin to draw the camshaft sideways which brings the more aggressive, longer duration cam lobes in line with the valves. As you close the throttle, the pin releases and the shaft with the less-aggressive cam profile gets pulled back above the valves, and the whole shebang takes just five milliseconds.

So it’s a combination of variable valve timing and variable valve lift and it’s all electronically actuated by the Bosch ECU. Captain Kirk would be impressed.

Especially if he’d recently ridden the outgoing 1200, which while was no slouch, it wasn’t a powerhouse. The 1250, on the other hand, is noticeably stronger through the entire rev range. But it wasn’t until several hundred kilometres into the test and onto the tarmac that I realised that this new engine really has added an extra dimension to the capability of the GS. You see, having a high-powered sportsbike is fantastic for spirited on-road riding and having a high-high-capacity machine tuned specifically for off-road capabilities is superb for hitting the beaten track. And while walking that fine line in between the two is a noble quest, it runs the risk of diluting each platform’s advantages as well as completely missing both marks.

The R 1250 GS is the best example I’ve seen so far which does a really good job at managing both tasks. It now has awesome superbike-like power to carve up mountain roads, but with the tractability and predictability to ably tame the wildest of dirt tracks and adventure trails. It’s quite incredible.

This added dynamic introduces a new sector to the top end of the GS range that we haven’t seen before. The engineers have focussed the increases to the small rev ceiling and the cam shaft tech has a seamless overlap between peak torque and peak power. I still don’t think the new engine turns the 1250 into a ballistic missile, but it’s not something that’s required for this type of riding and I think what’s on offer is a great fit.

Anyone familiar with BMW’s engine management and traction control systems will know they’re capable bits of kit, all of which improved considerably over the years. While we don’t see a massive change in the electronic capabilities of the 1250 compared to the previous 1200 model, it works exactly as intended.

The off-road modes are particularly impressive and are the safest option on a loose surface – a 250kg lump of metal packed with 135 horses is best handled with (cleverly engineered) care. Whoever designs the parameters at BMW left the fun option turned on and the electronics are there to safeguard major lack of skill determined by the rider, but they are far from foolproof.

I’ve spent a lot of time as a rider developing electronic systems and refining them in controlled environments, so I can really tell that BMW has paid close attention to developing an electronic system that works within the 1250’s chassis parameters. An example of this is the amount of rear end slide it allows on loose dirt. The (optional) Enduro Pro mode allows the rear end to slide to a certain point and is clever enough to maintain a full-blown slide, but doesn’t allow it to reach the point of no return. Unless of course, your rear-end is heading towards an embankment – then it’s less about engineered parameters and more about a heavy involvement of luck.

There are a plethora of settings you can change and customise in regard to throttle response, traction control intervention, electronic suspension settings and ABS controls. To be honest, the factory settings were completely fine for me; the changes to suspension damping on the fly were particularly noticeable, especially with a fully fuelled 30-litre tank between road and dirt modes.

While there are several factory settings at the push of a button that all offer something slightly different, I found that the Road setting or the Enduro Pro mode covered all bases more than adequately.

It’s important to note here that some of these settings come as an option. The R 1250 GS Adventure model only includes rain and road options, while the Adventure Rallye X variant (there’s actually 10 different versions of the R 1250 GS currently available – see breakout) comes with all the off-road fruit, including adaptable suspension damping and the full electronics package.  

BMW has certainly recognised the GS is going further and more remote at the hands of their customers than ever before, so reliability is something of utmost importance. The 1250 features an array of knock sensors that allows more flexibility of fuel quality and allows the use of a RON level lower than 95, which is particularly useful in the Australian outback.

With the quality of motorcycle that BMW produces these days and the decades of development that has gone into what has ultimately culminated in this R 1250 GS Adventure, it’s hard to identify any major downfall, and nor should we from a bike the history of which we can trace back almost 40 years.

The major updates between the current model and the outgoing one are apparent, and while it’s not a completely redesigned bike by any means, the changes are technologically substantial, they’re relevant and they’re noticeable. You get a lot of bike for your money and although its big physical appearance and weight may be daunting for some riders – especially those wanting to tackle the Aussie bush – it’s a surprisingly manageable bike that ticks a whole heap of boxes.

The 1250 is an incredibly capable all-rounder – so much so that it’s hard to understand why BMW Australia feels it needs 10 versions. But if you want one bike that will do it all and for as long as you want to do it for, you’ve found it.
