Harley-Davidson’s Evolution V-twin has powered the model’s Sportster since 1986. Over the years, the pushrod-actuated engine has earned kudos for its reliability and ease, and the Motor Company retains the V-twin within the air-cooled Sportster platform to this present day.
Of course, with the arrival of the 2021 Sportster S, the Evolution gave option to the Revolution Max 1250T attributable to Euro 5 rules. In the States, nevertheless, the Evo stays within the Sportster 883 and Forty-Eight. Harley nonetheless turns to the air-cooled V-twin after 36 years, however Chinese model Shineray needs in on the motion with its new 1200cc mill.
The firm doesn’t simply borrow the structure of Harley’s 45-degree V-twin, it additionally replicates a lot of the Evo’s cosmetics. From the cooling fins to the decrease rocker covers, from the chromed pushrod covers to the oil filter location, the Shineray unit virtually clones the legendary Motor Company engine.
The resemblance is greater than skin-deep too. Shineray’s engine additionally touts 4 camshafts that actuate one valve every due to starboard-mounted pushrods. The Chinese model can’t fairly replicate the Evo’s efficiency, although.
Shineray studies that its 1,200cc V-twin generates 60 horsepower and 66.4 lb-ft of torque with a 9.1:1 compression ratio. The 1,200cc Evo within the Forty-Eight, alternatively, boasts a ten:1 compression ratio that pushes efficiency to 67 horsepower 73 lb-ft of torque.
Shineray beforehand bought Italian agency SWM and launched an SWM-branded, liquid-cooled, 350cc, 550cc, 850cc, and 1200cc V-twins. However, the corporate hasn’t acknowledged what its new air-cooled V-twin will energy. Given the format, we extremely count on a throwback cruiser to showcase Shineray’s air-cooled V-twin.
Unfortunately, Europe most likely received’t obtain that impending mannequin attributable to Euro 5 homologation. Regardless of which cruisers make the most of Shineray’s V-twin, hopefully, its reign lasts so long as the Evolution’s.
