Harley-Davidson Reveals “Twin-Cooled” Engine with Precision Liquid Cooling

As we gleaned from recently revealed CARB documents, Harley-Davidson has introduced two new liquid cooled engines. The new engines use a combination of air-cooling and precision liquid cooling, similar to what BMW did with its 2013 R1200GS. One version of the engine, dubbed the Twin-Cooled High Output Twin Cam 103 will be used on the 2014 Harley-Davidson Ultra Limited and the Tri-Glide Ultra trike while the CVO Limited will use a 110ci engine known as the Screamin’ Eagle Twin-Cooled Twin Cam 110.

AMA Pro Racing Announces Basic Twins Flat Track Class for 2014 Season

AMA Pro Racing announced a new class for Flat Track racing designed to provide a new stepping stone for up-and-coming Pro-licensed racers, replacing the Pro Singles class in 2014. The new class, to be called Basic Twins, is more or less a revival of the Basic Expert Twins division that ran during the 2007 and 2008 seasons, but dropped when the Pro Singles class was introduced for 2009. The new class will give young racers a chance to showcase their skills on Twins, easing their transition to eventually enter the Grand National Expert Twins class.

Small-Displacement Class Considered for 2015 AMA Pro Racing Season

More and more manufacturers are entering the small-displacement sportbike market and AMA Pro Racing has taken notice, opening the possibility of adding a new racing class representing the growing segment. With plans to consolidate the Daytona Sportbike and Supersport classes and the Vance & Hines Harley-Davidson series signed through 2015, a spot will open up on race weekends for another racing class to support the premier Superbike Championship. The logical choice is to introduce a new small-displacement class.
