Top test BMW R 1200 RT – old against new

The touring boxer compared to the previous model

The new RT is not really new. Bad news? More like a good one. Because the current fine-tuning of the engine, fairing and chassis makes the touring boxer even better. How much is shown by a direct comparison with the previous model.

Perhaps with some motorcycles it is like wine, which it is usually better not to taste fresh, but rather to mature for a few years. Those familiar with the subject know: Motorcycles are also often best when they have been on the market for a few years, when errors and quirks in the first production batches have been corrected, when they have achieved an extraordinary level of maturity and quality after one or two updates.

This certainly applies to the boxer models from BMW. The boxer in general has been partly openly planed and polished in the past decade, but partly without fuss, so that many criticisms of the past are no longer an issue. And there have been quite a few of them since the four-valve boxer generation came onto the market in 1993. Annoying constant speed jerking, delayed throttle response, sticking gearshifts, cracking noises in the drive train, problems with the brake booster ABS – none of this is an issue today, or at least it has improved considerably in the past few years. And the RT in particular is now undergoing an upgrade with many small changes, which should further enhance its undisputed tourist qualities (see driving report in MOTORRAD 5/2010).

The touring boxer compared to the previous model

Successful operation: fine-tuning of shape and design makes the new RT more dynamic. Above is the earlier model, the test machine is currently for sale at Motorrad Gruneberg from Villingen-Schwenningen.

And while we’re at the comparison with the K models: The boxer doesn’t have to hide in terms of the chassis either. While the Duolever of the K is very stiff, but reacts rather bumpily to edges and breaks in the asphalt, the long-stroke Telelever of the RT simply irons away everything that the southern French road construction has in store for surprises and nastiness. A really excellent ride comfort of the highest level, which no other tourer can offer in this quality.

With the small disadvantage that the front suspension swallows the feedback and feeling for the front wheel in addition to all the rough terrain. This is particularly noticeable when switching from a motorcycle with conventional chassis technology; the first few meters on a Telelever boxer take getting used to. Incidentally, this applies even more to the 2008 test machine, which was fitted with Bridgestone BT 020 tires. The Metzeler Roadtec Z6s of the new RT build trust more quickly. In general, the Metzeler with more neutral steering behavior and better grip – especially in cold and wet conditions – are the better choice, even if the Bridgestone provide more stability at high speeds.

The new expansion stage of the ESA electronic chassis works with the same settings as before, but the additional adjustment of the spring rate on the rear strut enables a wider setting range. That is not necessarily decisive for the war in solo operation. But especially with a high load, there are now more reserves at the rear, the RT looks more stable and tighter with a sporty setting.

Pure touring luxury: You can’t get more comfort, whether old or new RT, alone or as a couple.

Slight progress – under this motto one could also classify the effects of the interventions on plastic clothing. In direct comparison, the new cladding appears less flat. Although the external shape has changed little, BMW was able to improve the wind protection. This is mainly due to the disc, which is now wider in the upper area. It’s nice that this effect is particularly noticeable in the speed ranges that are common on country roads. The current circumnavigates the upper body area less turbulently, so you can drive very relaxed with the windshield slightly raised in terms of noise and wind protection. The old model always needs a higher setting for the same effect, at which the edge in the field of vision is then disturbing. Most of the tourists are only on the highways when they are on the high road, and the new window improves visibility through less distortion. The front passenger also benefits a little from the aerodynamic advantages of the new windshield. Incidentally, according to BMW, it also fits the old model.

The workplace has also been renovated. Ergonomically everything stayed the same, unfortunately the desire for an adjustable handlebar remained unheard of. The existing one puts particularly tall drivers in the supine position, and with a hollow back the driving experience is quite passive. In terms of comfort, however, there are no objections, the RT workstation is still one of the most convenient of all. The operation of the radio represents a step forward, the ugly knob is no longer necessary in favor of a simple operating ring on the handle. Knubbel is now available in the form of towering containers for the hydraulic fluids, which thanks to rubber bearings shake strangely on bumpy roads. Everyone can judge for themselves whether this is a step forward compared to the integrated solutions in the previous model. The same applies to activating the indicators, which has always polarized. The previous BMW solution with three counters had its fans, and those switching from other makes will certainly prefer the conventional solution of the new model.

And they will probably be the target group in the first place. Because if you already have an RT, you don’t have to sell it cheaply for the new model.

As promised, the new Dohc engine delivers more power, especially in the important medium speed range. In addition, the wave troughs are somewhat leveled in the torque curve. Both RT models remain slightly below the nominal output, the new one outperforms its predecessor by a good two hp. The higher maximum speed is less relevant for a tourer.

Brake measurements

MOTORCYCLE test course, values ​​from the brake test averaged from the three best driving tests.

The consistently high level of deceleration without any dips leads to extremely short braking distances. In doing so, the Telelever fork prevents the vehicle from dipping away despite a long delay. The rear wheel maintains contact with the ground even when braking hard. Therefore, the RT remains stable on course. All in all, it is relatively easy to slow down the RT at the limit.

Conclusion

There’s not a single reason to buy the new RT – there are many. The changes to the engine, chassis and bodywork are by no means serious, but they add up. The bottom line is that the RT remains what it was: an extremely luxurious and comfortable, but despite the extensive equipment, by no means overweight touring boxer with a unique driving feeling.

Scoring

Category engine:
The drive is not the most powerful part of the RT, with 110 HP it is not exactly overpowered. Although the boxer is sometimes a bit sluggish and indirect, it still fits perfectly with the character of a touring machine. Vibrations are undeniably present, but they are never really annoying. Points of criticism remain the dry clutch, which smells foul under load, and the long shift travel of the transmission, which only shifts hard in the two lower gears.

Category chassis:
The handiness of the thick ship is always striking. With the Metzeler Roadtec Z6, the RT circles around bends more neutrally and more precisely, but when it comes to feedback, the Telelever chassis leaves something to be desired. Thanks to the special equipment with ESA chassis, the setting options are varied and clearly noticeable, which means that the RT also collects many points in the pillion rider. The driving comfort on rough roads is outstanding.

Category everyday life:
Comfort is also the buzzword when it comes to ergonomic conditions; both seats are extremely comfortable even on long tours. The RT is also absolute top in terms of equipment, luggage storage, wind protection and light. The large tank enables enormous stages. Overall, not much more is possible in this chapter in terms of points. The deeply placed mirrors alone have to take criticism.

Category Security:
It’s a shame that the brake control is not quite as good as its excellent effect. Even with a pillion passenger, the braking distances are extremely short. The righting moment in curves is within limits, handlebar flapping remains a foreign concept even on extremely undulating roads.

Category costs:
In terms of consumption, the RT has increased a little, 4.9 instead of 4.6 liters are still good in view of the mass and dimensions. Unfortunately, she would like to have Super Plus. A three-year guarantee like Honda’s VFR would of course also be nice.

   Max points
  BMW R 1200 RT
 Overall rating  1000  734
 Price-performance note  Top grade 1.0  2.4

The price-performance ratio:
An RT is of course not cheap – but good. The high score therefore makes the price appear reasonable.

The cylinder of an old boxer engine.

Trick question: When did BMW build the first boxer? Correctly googled, that was in 1923, the machine was called R 32, back then with a cardan. Visually, the first boxer still has a few things in common with the current one; the outstanding air-cooled cylinders are now more than ever a unique selling point for Bavaria.

Technically, however, practically no stone has been left unturned since then. The last major intervention happened in 1993 when the boxer got four valves instead of two. That also brought a leap in the possible power output. Because the filling with fresh gas is a fundamental shortcoming of the boxer, the outward-facing cylinders result in unfavorable channels that are curved towards the engine block.

Jahn

The cylinder of a new boxer.

In principle, the current expansion stage does not change that. The shape of the channels remained, but the lighter masses of the valve train allow higher valve accelerations, which in turn improves the filling. The maximum speed at which the valves or rocker arms or rocker arms can no longer follow the cam tracks also increases. These better prerequisites for a Dohc head can either be converted into higher peak performance – the HP2 Sport produces at least 130 hp at 8750 rpm – or the torque is maximized at low speeds, as with the RT and GS. In addition, the radially arranged valves result in a compact, less rugged combustion chamber. Nevertheless, BMW left the compression at 12.0, Super Plus is required for full performance.
