Harley'sSoftail(soft tail)series is long、Unique product family。from1984Harley's earliestFXST Softailsince listing,Various models of softtail models continue to be introduced,LetSoftailBecoming a Harley Classic。HarleySoftailnewcomer to the family,Newly developedSport GlideDress up!

Revolutionary cylinder head

mention harley,Riders immediately think of vertical placementVType two-cylinder engine,And the accompanying low-speed high torque、Unique vibration rhythm and powerful exhaust rhythm。indeed,This is standard on Harleys and even American cruisers,But while sticking to tradition,this oneV2The engine is actually improving all the time,from Fhead、Flat head、fist、pan head、iron head、shovel head to“double cam”、“evolution”、“reform”,Harley's power heart keeps evolving。

again,Harley-powered heart has come to an evolutionary moment。This engine is a new generation of new research and developmentV2engine。over the years,Harley's powerplants all have distinct personalities,for exampleOHVvalve train,This is a relatively old engine intake and exhaust technology,The camshaft is mounted on the lower side of the cylinder,Push the rocker arm up with the longer push rod,Then press down through the rocker arm to open the valve;The valve is set on the cylinder head,This way the combustion chamber can be optimized to be hemispherical or wedge-shaped,Thereby improving the compression ratio and thermal efficiency of the engine,However, this advantage is only relative to the side valve train.。The overhead valve engine has the characteristics of low speed and high torque,and can be adjusted byVThe angle of the two cylinders to obtain different vibration rhythm and exhaust sound,has a strong personality,This is why, although more advanced overhead camshaft engines appeared later,But Harley still sticks to production technology“outdated”ofOHVengine reason。Now,Harley's latest generation of power heart still insists on overhead valves,But for the first timeOHVmake major innovations,each cylinder2valve increases to each cylinder4valve,This ensures compliance with current emissions and fuel consumption、On the premise of reliability and other requirements,Enhanced power and torque output。

stronger power

last generationSoftailThe family carriesTC103engine,Displacement is1690mL,Able to burst the maximum torque132N·m(3000r/min)。Now,SoftailThe newest member of the familySport Glidemore broad-minded,Expand the engine displacement to1745mL,increased55mL。

exist4With the support of valve cylinder head and larger displacement,Sport Glidegained more power,The maximum power is62kW(5020r/min),Maximum torque up to145N·m(3250r/min),Enhanced over the previous generation10%。Of course,Harley's unique low-speed and high-torque characteristics are still outstanding,When the speed is as low as1700r/minTime,output strong power,continued to increase since then、maintain high torque output,until the speed red line is reached5500r/min,The electronic speed limiter starts to interfere with the speed。Harley claims,With more valves、Larger displacement and bull-like low-speed high torque,compared to the previous generation,Sport GlideAccelerate from start to100km/h,it's running out10%,Create more power for the rider、More refreshing speed stimulation!

asSoftailThe newest member of the family,Sport GlideIt can be said to come from behind,Take advantage of the latecomer,That is to absorb the advantages of the brothers,both brothersHeritagetravel features andFat Bobathletic performance。

Batwing windshield,It turned out to be the standard configuration of the Harley travel family.,now thisDNAalso inheritedSport Glidespan。but,Since it is located in“light travel”,Sport GlideThe bat wing becomes very mini。Modeling design by computer fluid dynamics software,Wind Tunnel Tested at Wichita State University,And the actual test drive under various road conditions, Sport GlideThe mini batwing combines function and personality,Not only provides the right amount of wind protection when driving,Reduces the pressure of storm winds at high speed,Makes the rider less prone to fatigue during long-distance travel,And no heavy feeling,will still give you the wind to fly、Embrace the Air Free Cruise Experience!

Two side boxes as standard,Not only is it convenient for riders to store luggage when traveling,and compact design,Integrated with the vehicle,No bulky feeling at all。Better yet,Either the two side boxes or the batwing windshield,can be easily removed in seconds,No additional tools required。so,“light travel”ofSport Glideshaken up,Immediately convert it into a simple and tough standard cruiser!
