2. Harley-Davidson Reveals New Liquid-Cooled Engines

Harley Street Production Shoot

Traditionalists might not like it, but the fact is it was only a matter of time before Harley-Davidson made the transition to liquid-cooled engines. Yes, the VRSC has been around since 2001, but the Harley faithful never truly embraced the liquid-cooled V-Rod. But with worldwide emission standards getting tighter and tighter, it was inevitable that Harley-Davidson would begin embracing the technology.

We figured something was up when the California Air-Resources Board released an executive order on some new 2014 Harley-Davidson models with significantly lower emissions figures than previous models.

Harley-Davidson proved our suspicions correct a few days later revealing its new Twin-Cooled engine technology which combines air-cooling with a precision cooling system that routs liquid coolant around the exhaust valves. The new Twin-Cooled High Output Twin Cam 103 debuted on the 2014 Ultra Limited and the Tri-Glide Ultra trike while the CVO Ultra Limited received the larger Screamin’ Eagle Twin-Cooled Twin Cam 110 engine.

The Twin-Cooled engines marked a significant shift for Harley-Davidson, but The Motor Company had another surprise saved for EICMA where it revealed models in the models in the Street 500 and Street 750 with a new liquid-cooled Revolution X engine.
