Tall ship

Often the enthusiasm for the sleek disguise while standing is quickly followed by disillusionment: a thundering hurricane at a higher speed. Accessory disks can provide peace of mind?

Racing machines are characterized by their uncompromising nature. No unnecessary frills, the silhouette is narrow and small. When the driver crouches on the straight behind the fairing, man and machine seem to merge into one. But motorcycling in real life looks different. Although most of the road-going offshoots of the racing machines only wear mini dresses, 99 percent of the time the driver sits upright on a sports machine. There can hardly be any talk of real relief through the flat windshields. The desire for better wind protection often arises not only from tall drivers. This is what the accessories trade promises, where you can find taller, wider or aerodynamically shaped replacement windows for series fairings for almost all machines with cladding, from super sports cars to touring bikes.
MOTORRAD tested two completely different motorcycles to see what the propagated properties of these accessory screens are. The Honda CBR 1100 XX represents the sporting guild. The fairing of the sports tourer is kept very flat, the tested windows are up to twelve centimeters higher. In terms of price, the accessory disks in the case of the Honda are definitely an alternative, at 100 to 200 marks they are all well below the original part, which costs almost 380 marks. Those who are satisfied with the series fairing will also find inexpensive original form windows from some manufacturers as a replacement for a scratched or destroyed window.
All tested windows for the CBR offer more protection from the airstream. If you want to keep the sporty look and prefer a corresponding driving style and sitting posture, it is best to drive with the MRA racing screen. The MRA spoiler screen and the JF part offer better wind protection, especially for tall drivers.
In the case of the BMW R 1100 GS, the demands on the fairing are basically no different. Although it does not reach the high speeds of the double X, many riders demand good wind protection for long daily stages from a travel enduro? especially since the GS is not exactly one of the slow ones in its class. The standard cockpit fairing is not fully convincing on this point. It noticeably relieves the upper body, but especially with tall drivers, the head is fully exposed to the wind. Many GS drivers also complain about the loud noise development, as the helmet is exactly in the turbulent zone.
In terms of costs, the series part, which costs less than 100 marks, is unrivaled. With prices of up to 500 marks, expectations of the accessories are considerable. But the buyer doesn’t have to shell out that much, because the most expensive part of GS Fun Factory doesn’t want real driving fun, the only argument remains at most the carbon design. The other accessory discs bring some significant improvements. Even tall drivers sit relatively calm and protected behind the Wunderlich windshield, but the windshields from JF and Ermax can also noticeably relieve the driver of wind pressure and reduce the noise under the helmet.

Difi airflow

Alternatives

Although the BMW R 850/1100 GS is not a real rally bolt, many drivers want a sportier, off-road look. Touratech (phone 07728/92790) has developed the Desierto cladding, which costs 1199 marks. The scope of delivery includes the tinted spoiler screen, two DE headlights and a new bracket. The original instruments are retained. For an additional 100 marks there is a rally version that can hold the necessary navigation instruments such as road book or GPS. A version for the 1150 GS costs 949 marks, this is combined with the standard headlights. Wudo (phone 0231/850091) has a tour-like fairing for 576 Marks on offer, the paintwork costs an additional 279 Marks. Additional wind protection can also be achieved for significantly less money. Touratech charges 109 marks for the spoiler attachment; it is simply attached to the standard disc and lashed with a strap. The effect is amazing, the small spoiler directs the turbulent flow further upwards. This reduces the air resistance on the helmet a bit and noticeably lowers the noise level, you are happy to accept a little more turbulence on the upper body.
