I ride bikes for a living, in case you didn’t know this already. I ride more miles on two wheels in a year, than the average American does in their automobile (I put more four-wheel miles down a year than the average American does as well, if that gives you any idea how much of Asphalt & Rubber is written while on the road). With all this riding, I’ve become increasingly concerned over my hearing, as I’d like still to have it when I’m older. Thus for my own personal benefit, I’ve been trying out the different kinds of ear protection that are available to motorcyclists, as well as a variety of helmets from manufacturers (articles surely to ensue).

So when the Journal of the Acoustical Society of America published a study titled “Aeroacoustic Sources of Motorcycle Helmet Noise” in which the various frequencies and decibel levels of helmet-generated noise were measured and tested, I became very interested in the study’s findings. Bear in mind I’m a staunch believer in helmet laws and riding with a full-face helmet (my apologies to the Libertarians in the group), so when the study suggested that my two main concerns regarding my head may be at odds with each other, it piqued my interest.

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.

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.

Gov. Arnold Schwarzenegger has seemingly just terminated loud and free flowing exhaust systems on motorcycles in the Golden State of California. Affecting only motorcycles and aftermarket parts made in 2013 and on, the California’s law cracks down on noisy bikes by imposing fines  of $50 to $100 for first-time offenses, and fines of $100 to $250 for subsequent offenses.

The law’s passage has been a big issue for Californian motorcyclists, with the fires being fanned by both the MIC and AMA, who would like to state and national exhaust noise laws adopt an SAE standard. The reality though is that California’s law brings the state in-line with Federal laws on the issue, which already superseded California’s lax standards, which were widely unenforced by the state’s law enforcement officers.

With nothing changing from a legal perspective, it remains doubtful that California LEO’s will ramp-up their enforcement of the new provisions, considering how seriously they took the federal statutes.

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.

Our poor friends down under are about to get a further crackdown on what can and cannot be done out on the asphalt. The Aussies are set to put into place a series of roadside microphones to crack down on offending and unrestricted exhaust pipes. Similar murmurs are also being made back on the Queen’s Island. 

The fully automated systems have been in development for the last three years and are now set to be rolled out in several states and territories down under. According to a report in Australia’s The Newspaper, the camera-based system utilises a set of microphones to record noise levels and, when the set threshold is exceeded, a ten second video is stored and a ticket automatically generated. Apparently the machine can hold data for up to 10,000 tickets before it needs to be reset.

There are rumors that soon even thinking about a wheelie will be illegal. Ok, George Orwell…you win.
