EPA REGS AND Harley's 2000 and 2450cc V-Twin Motorcycles?--
EPA documents show design basics and performance
info for 2450cc V-twin, but they also raise a few questions. Any new
mega-displacement liquid-cooled Harley-Davidson motorcycle engine would
incorporate some of the technology from the VRSC Rod series V-twin engines. Is
Harley about to join the displacement race? That topic has been buzzing around
the internet with the discovery of Environmental Protection Agency (EPA)
documents mentioning a 2450cc V-twin engine. With Harley now running at the
bottom of the big-twin displacement class, it's only a matter of time before
Harley, which was once distinguished by having the largest motorcycle engines on
the road, produces a bigger V-twin.
The EPA emissions document in question (scroll down to the last three pages, 8
through 10, of this PDF) shows testing results for liquid-cooled 2450cc and
2000cc Harley-Davidson V-twin engines. Power for the 2450cc version is listed as
98 kilowatts (131 horsepower) at 5000 rpm with 133 newton-meters (98
foot-pounds) of torque at 3500 rpm. The weight (presumably the GVWR) is listed
at 1260 pounds. Since the fuel-tank material is listed as nylon, it would
presumably be an under-seat style. The fuel-injected engine uses air injection
and catalyst to reduce exhaust emissions.
However, don't get too excited yet. The title page (page 7) for this section is
labeled as a "Hypothetical Application." There are other hints that the bike is
also hypothetical. On the last page, the "Test Date" is listed as July 2007. The
names of the bikes - Heritage Ultra Tail and Heritage Ultra Tail Special - sound
more like jokes than anything Harley would bring to market, and a bike
