I have to admit, the whole E15 controversy that has been brewing between the EPA and AMA has me a bit confused. Namely, I do not know how the EPA ever thought that a four-gallon minimum purchase requirement solved anything for powersport users who were concerned about putting E15 in the tanks of their motorcycles and ATVs.

Realizing that a solution to the actual problem had to be devised, the EPA has now dropped the four-gallon minimum on fuel pumps that dispense E10 and E15 from the same pump, and instead the government body says it will likely require gas stations to label shared pumps, as well as offer a dedicated E10 pump/hose for vehicles.

You may have been hearing a bit about this EPA compliance spreadsheet that has been outing more than its fair share of new motorcycles for the 2013 model-year. Tipping us off to a number of Kawasaki’s soon-to-be-announced models, like the 2013 Kawasaki Ninja 300, the 2013 Kawasaki Ninja 400R, the return of the 636cc Kawasaki Ninja ZX-6R, our continued torture with the carb-based Kawasaki Ninja 250R, EPA document also makes mention of a BMW F800GT, as well as a Ducati 1199 Panigale SP.

Two curious things happened today: an EPA certification document outed details on the 2013 Kawasaki Ninja ZX-6R and Kawasaki USA announced the “global debut of its 2013 line of iconic Ninja motorcycles in New York’s Times Square.” Add in to the mix that the EPA documents also make mention of Kawasaki Ninja 300 & Kawasaki Ninja 400R models, along with the recently updated Kawasaki Ninja 250R, and Team Green could very well be dropping the news about three or four brand new models for the US market.

Of course what is really interesting about this news is how Kawasaki could do a two-fold offer of 300cc & 400cc bikes in the US market, and how those two models would fit alongside the Ninja 250R, which we can only assume will be updated in the United States to the model that was debuted in Indonesia earlier this month. Or will it?

The 2013 Kawasaki Ninja ZX-6R is set to return to a 636cc displacement, according to a spreadsheet released by the United States Environmental Protection Agency (EPA). With alleged spy shots of the new ZX-6R already hitting the press, the supersport-class bike noticeably takes a design cue from its liter-bike counterpart — a move that should surprise no one.

Listed by the EPA as making 129 hp (96.4 kW) at the crank, the move to have the 2013 Kawasaki Ninja ZX-6R be a 636cc displacement machine is interesting, as the EPA’s document does not list a 599cc Kawasaki Ninja ZX-6RR analog, something the Japanese brand did last time it bumped its middleweight’s displacement figure beyond the norm.

Well, 2011 as a year is finally over, and for the motorcycling community it was quite a year. As we begin 2012, we here at Asphalt & Rubber are of course not immune to the desire to summarize and highlight the passing of 2011. So we accordingly assembled 11 of the most important events that shaped motorcycling this past year and changed the way the sport, the industry, and the community will grow in the years to come.

Picking only eleven moments in a single year is no easy feat, though some of the events in our selection are obvious choices because of their magnitude. However, some of the less obvious picks (and we are sure there will be suggestions for alternatives in the comments), stem from the theory that 2011 saw moments whose importance has yet to be fully appreciated at this point in time. Enjoy and a Happy New Year to our loyal A&R readers.

The next hot-button issue concerning the EPA and motorcycles is not gas and particle pollution like you might expect, but instead simply noise. There’s always been a battle between the straight-pipe running motorcycle contingency (you know who you are), whose loud pipes have been an earsore for both regular citizens and motorcyclists alike. With the EPA cracking down at a federal level, and states like California adopting similar provisions, it would seem the day of the straight-pipe are going the way of the dodo, but the issue doesn’t stop there.

Take the 2011 Kawasaki ZX-10R, the would-be superbike of 2011 (if Kawasaki ever sends us one from the press fleet), which boasted an astonishing 207hp at the crank with ram-air. Motorcycle enthusiasts of the United States were disappointed when the machine arrived on American soil, and learned that the new ZX-10R had been de-tuned to meet EPA standards. Losing roughly 10hp, the presumption was that the 2011 Kawasaki ZX-10R had failed to meet emission standards, but the reality is that Kawasaki had to de-tune the bike in order to make it quieter.

Shortening the rev range by 750 RPM, Kawasaki basically gamed the system on how the EPA measures sound, which is based off a percentage of the total rev range. Perhaps the first to comply with this new standard, American motorcyclists can look forward to different performance spec-sheets on sport bikes from those found abroad in the soon-to-come future. Of course as is the case with the Kawasaki ZX-10R, bypassing the changes made to meet EPA compliance is a simple matter of modifying the electronics package, and then Bob’s your uncle. However would-be tinkerers may want to think twice, as a new device known as the Noise Snare is set to make its debut on catching overly-loud motor vehicles.

The AMA has announced its AMA Motorcyclist of the Year, and  the organization that represents all American motorcyclists has chosens Gov. Arnold Schwarzenegger of California for its yearly distinction. Using the award as a platform to denounce the outgoing Governor, the AMA in its announcement chastised Gov. Schwarzenegger for his signing of California Senate Bill 435, which brings EPA noise enforcement standards to the Golden State. We’ve already addressed here at A&R how California’s adoption of this law essentially is a moot point legally, but the AMA’s grandstanding on this issue smacks speaks to a larger issue that goes to the core of the organization.

Clearly unable to self-regulate and educate the very people it is supposed to represent, the AMA is instead more concerned with tar and feathering politicians and governmental agencies for addressing a growing issue that negatively affects the relationship between motorcyclists and the general population. The simple truth is that a small portion of our community feel the need to compensate for their short-comings by running straight-through exhaust pipes that not only annoy normal citizens, but other motorcyclists as well. How is this an issue that 99% of motorcyclists can’t get behind?

While the AMA has some good ideas on how to measure and enforce lower sound levels from motorcycles, the organization’s lack of anything resembling efficacy in getting those provisions adopted should not create an open license to lay the blame on others (well except maybe the MIC, which is just as culpable for this problem as the AMA). While it’s easy to chastise Gov. Schwarzenegger for signing a bill into law, we think the AMA should take a harder look in the mirror on how motorcyclists created this problem for themselves, because in the end we’re the ones that ruined a good thing.

AMA press release after the jump, but for the record we would have given the award to Erik Buell…but hey that’s just our opinion.

We just got off the phone with Kawasaki HQ, and it’s official: the 2011 Kawasaki ZX-10R will inadvertently get a power decrease when it comes to the United States because of the EPA’s regulation of noise pollution, confirming earlier rumors from this week. The issue surrounds the EPA’s new methodology for measuring exhaust noise levels, which now involves taking the measurement at a percentage of the total rev range, instead of a specific rpm value.

The result is that the 2011 Kawasaki ZX-10R passes the Euro III standards, but fails the EPA standards in its unadulterated form. To come into compliance with the EPA’s Noise Control Act, Kawasaki has lowered the rev-limit on the 2011 Kawasaki ZX-10R by 750 rpm in order to meet the new criteria. The byproduct of lowering the rev-limiter will reduce the new ZX-10R’s maximum power output, but Kawasaki isn’t saying by how much.

Immediately after the launch of the 2011 Kawasaki ZX-10R, which claimed a 207hp figure at the crank with ram-air (197hp sans the air), rumors began to swell that the new ZX-10R’s peak performance figure would be drastically less in the American market. Apparently and supposedly due to federal regulations by the EPA, Kawasaki will be lowering the rev-limiter on the 2011 Kawasaki ZX-10R in order to comply with US government provisions.

Whether those rumors are in regards to the ZX-10R’s emissions or noise levels at that rev range is unclear at this time, but speculation that the power decrease is due to the new 10R’s peak power figure being north of 200hp are completely unfounded (Editor’s note: the United States has no provisions, at both the state and federal level, that cap motorcycle horsepower performance levels from the factory). We’ve reached out to Kawasaki for an official response on the issue, more as we get it.

A California State Assembly committee has endorsed legislation that would to require motorcyclists in the Golden State to have an EPA-compliant exhaust system on their 2011 or newer motorcycles. Two days ago the Committee on Transportation approved Senate Bill 435 with an 8-4 vote, which would make it illegal to operate a 2011 or newer motorcycle with an exhaust system that doesn’t have an EPA label that certifies it as meeting noise limit standards. According to the bill, riders would incur a “fix it” ticket if caught without their EPA exhaust sticker if the bill came into law.
