You already know BMW’s new adventure tourer, the S 1000 XR, will need 120/70R17 and 190/55R17 tires (front and rear, respectively). What you may not know is that Pirelli’s Scorpion Trail II tire comes in those exact sizes, plus several more. This will enable XR riders to enjoy a new enduro street tire that is a synthesis of the best features offered by an off-road product and those guaranteed by a sport-touring tire.
Originally developed for the Ducati Multistrada 1200, the new Scorpion Trail II is the synthesis of two worlds: the field of off-road competition and the long distance road trip. Designed for the most demanding motorcyclists, it key features include high mileage, consistency of performance for its entire tire life and top-notch wet performance.
The Scorpion Trail II is the new Pirelli tire specifically designed to meet the most demanding expectations of this market, with an aggressive tread pattern supported by strong technological innovation, giving good stability even at high speed, traction on dirt, handling, comfort and grip in all riding conditions.
The word Scorpion recalls immediately the range of Pirelli products intended for use in off-road competitions, not only in the two-wheel world but also on four wheels. The products in the Scorpion line are present in off-road car racing competitions, in the Enduro and Cross Country Rally World Championships, and in the Motocross World Championship, where the range of off-road Pirelli tires has been the undisputed leader with 62 world titles over 30 years. The enduro street market remains a segment where motorcyclists’ expectations are always high and where motorcycle manufacturers continue to invest in launching new products every year.
Suitable for the latest generation adventure touring and enduro street motorycles able to tackle even long journeys, with light off-road sections, the new Scorpion Trail II is a tire with good road performance and also capable of tackling unpaved surfaces. It is designed for motorcycles such as the BMW S 1000 XR and Ducati Multistrada, models which are increasingly being purchased by riders strictly for use on the road but which, if necessary, may also face stretches of dirt and light off-roading.
The enduro segment was born during the 1980s when motorcycles equipped with a 21" front tire began winning the most prestigious African rallies. Gradually these bikes reached the road in long distance rides, and thus their evolution of use reached a parallel evolution of the size of the tires they mounted: the rear wheels became larger, while the fronts shrank to 19".
Pirelli created the Scorpion Sync, the first knobby-looking street sport tire in 120/70-17 and 180/55-17 sizes. Now, a decade later, Pirelli will once again be the leader of a revolution in this segment, thanks to the introduction of the Scorpion Trail range in the rear dual-compound 190/55-17 size that marked the dawn of a new generation of street enduro machines such as the new BMW S 1000 XR.
The innovative tread pattern of Scorpion Trail II is the result of this famous off-road line, enriched with the experience gained by Pirelli with the development of ANGEL GT, considered the reference tire in the sport-touring segment. The tread pattern of Scorpion Trail II therefore has an aggressive look typical of an off-road tire, behind which there are class performances combining the features of an enduro product, with those of a sport touring one. The side grooves of the new Scorpion Trail II have been designed to ensure optimal drainage in case of rain, while the layout and "binary open" shape of the central ones not only contribute to the drainage of water but also ensure better traction, greater stability and more regular wear.
Pirelli was the first company to introduce the bi-compound solution in some rear sizes of enduro street tires with the Scorpion Trail. Today, the Italian tire company is able to apply this technology to all of the rear tires in the Scorpion Trail II range. Compared to its predecessor, the new tire has a compound developed for high mileage without compromising cornering performance, and it is especially developed to offer excellent wet performance. The side compound was designed to optimize the balance between performance on dry and wet roads.
Thanks to a shorter, wider, contact patch area, the profile helps to reduce and level the wear of the tread, thus ensuring greater mileage. With the application of new profiles, it has been possible to increase the handling which remains unchanged throughout the whole life of the product. All of these factors benefit traction and give better motorcycle control.
Thanks to the structure developed to enable the central and lateral compounds to work optimally, the new Scorpion Trail II ensures high performance, even at full load or with heavier motorcycles. This provides improved wet performance than its predecessor and an incredible versatility, making it comfortable even for long trips and on winding roads and in case of adverse weather conditions.
The new Scorpion Trail II is Z-rated for speed and available in the following sizes:
FRONT: 90/90 R21; 100/90 R18 and R19; 110/80 R19; 120/70 R17 and R19
REAR, all R17: 13/80; 140/80; 150/70; 160/60; 170/60; 180/55; 190/55
These sizes should fit the following BMW motorcycles: F 700 GS, F 800 GS & GSA, R 1100 GS, R 1150 GS & GSA, R 1200 GS & GSA, HP2 Enduro. They may fit other bikes as well - always check the manufacturer’s specifications before buying or fitting new tires.
