The V-STROM 1050XT, which was modified last year, has a lightweight aluminum frame with the same 1037cc displacement as its predecessor. The result was a decent 6.6L/100km urban fuel consumption, 3.3L/100km cruise speed and 5.3L/100km test fuel consumption.

No. 8  triumph Speed Twin

Triumph positioned the Speed Twin as the "Custom Roadstar", with a retro look but a formidable performance. Based on the engine and body structure of the strongest Thruxton R in the Bonneville, it is equipped with a 1200cc liquid-cooled 270° crankshaft parallel twin-cylinder engine. Although the maximum horsepower is only 97ps, but the huge displacement brings strong torque, in terms of fuel consumption urban 6.5L/100km, constant speed fuel consumption 3.3L/100km, test value 5.2L/100km.

No. 7  Ducati Diavel 1260

Diavel is the most special ducati product line, from the appearance of Diavel can be seen with the Style of American cruise car. The l-type twin-cylinder engine has a displacement of 1262cc and can produce a torque of 129N·m at a very low speed. Nearly 250 kg of car weight, fuel consumption is surprising, with 6.6L/100km urban fuel consumption, 3L/100km constant speed fuel consumption and 5.2L/100km test value ranked seventh, this figure even more than many medium displacement models.

No. 6  BMW R nineT Scrambler

The R nineT Scrambler is based on the R nineT, originally intended for retrofitted, free-riding yuppies. The R nineT Scrambler, powered by a 1170cc horizontally paired twin cylinder engine, achieves fuel efficiency of 6.5L/100km in urban areas, 3L/100km at cruise speed and 5.1L/100km at test speed.

No. 5  Scrambler 1200 XC

The Scrambler 1200 XC is an all-purpose vehicle that not only rides around the city, but also takes you on forest trails. The Scrambler 120 XC's engine is based on the Bonneville T120's high-torque liquid-cooled SOHC 8-valve 1200cc side-by-side twin-cylinder engine, capable of producing a maximum of 91.2ps horsepower, Meanwhile, the urban fuel consumption of 6.2L/100km, constant speed fuel consumption of 3.3L/100km and test value of 5L/100km are still maintained.

No. 4  BMW R nineT

Since its launch, BMW R nineT has succeeded in attracting many people who like modification with its retro appearance, extremely simplified design style and impressive dynamic performance. Equipped with a 1170cc horizontally opposed twin-cylinder engine, it can output 110.5ps maximum horsepower at 7500 RPM and 116N·m maximum torque at 6000 RPM, which is quite powerful for retro streetcars. At the same time, THE fuel consumption performance of R nineT in the urban area of 6.4L/100km, cruise speed of 3L/100km, test value of 5L/100km, successfully made it into the top five fuel economy list.

No. 3  Honda CRF1100L Africa Twin

The third place was achieved by the Honda CRF1100L Africa Twin with 6L/100km urban fuel consumption, 2.8L/100km constant speed fuel consumption and 4.7l /100km test values. Honda by extending the engine stroke 6.4mm, to achieve the displacement increase, power also increased 6ps horsepower, at 7500 RPM can output 102ps maximum horsepower, and the maximum torque is 105N·m. An aluminum cylinder liner and larger throttle for lightweight and vibration reduction, a redesigned cylinder head, and a substantially revised combustion chamber design and ECU Settings give the new Africa Twin even more sound and performance.

No. 2Triumph Bonneville T120

The Bonneville T120 was hailed as one of the most talked about cars of the late 1960s, the model of the Triumph twin-cylinder and triumph's most popular car ever built, and it's still going strong today decades later. The Bonneville T120 has evolved to be a classic blend of the modern and the modern. Powered by a state-of-the-art electro-injection system, the Bonneville T120 features a new engine and tyres that deliver power, handling, comfort and fuel efficiency. The 1200cc liquid-cooled twin-cylinder engine with 80.1ps horsepower and 105N·m torque achieved fuel consumption of 5.9L/100km in the city, 2.7L/100km and 4.6L/100km at constant speed, making it the runner-up for the most fuel-efficient upgraded car.

No. 1 Triumphant Bonneville Bobber

The winner of this year's most fuel-efficient car upgrade was the Triumph Bonneville Bobber, which achieved an impressive 5.4L/100km in the city, 2.7l /100km at constant speed and 4.3L/100km on test. The Bonneville Bobber is powered by a 1200cc parallel twin-cylinder engine with 77ps horsepower and a maximum torque of 106N·m at 4000 RPM, as well as a dual air filtration system for improved intake efficiency. The Design of the Bonneville Bobber not only takes the classic British style, but also incorporates elements of the American Bobber. In contrast to the chrome plating that is common in the British style, the Bonneville Bobber uses a low-key monochrome coating to make the car accessible to more reserved people. Also let like personalized modification enthusiasts have more modification space.

The flagship models of various motorcycle brands are generally up to the liter level, muscular and powerful appearance, abundant power and the top black technology in a body. At the present stage, the driving pleasure brought by the traditional large displacement fuel engine is unmatched by the small displacement and new energy models. Even though the price and maintenance cost are high, it still makes people unable to stop. With the improvement of people's awareness of environmental protection, new energy engines and models emerge in an endless stream, low energy consumption and high endurance will become a development trend.
