It looks like Europe’s new Euro4 emissions standard has claimed its first victim (if you don’t count the exhaust pipe on the Ducati 959 Panigale), as neither KTM nor Husqvarna will be producing their 125cc two-stroke enduro models for 2017, and the foreseeable future afterwards.

The move is a euros and cents decision, and a slightly complicated one at that, but it boils down to the fact that making the small-displacement smokers meet the more stringent Euro4 emissions requirements was financially prohibitive.

Last week, we published the story about how the EPA was laying claim to emissions regulation on production vehicles, even when they were being used privately for off-highway uses, such as racing.

This news sent a shockwave through the motorcycle and automotive communities, because this viewpoint from the EPA would drastically change not only the racing and track-enthusiasts landscape in America, but also the aftermarket sales of performance parts that are sold through the “race only” loophole.

As you can imagine, two-wheel and four-wheel enthusiasts were incensed over this revelation from the EPA, and I am sure a number of pitchforks were sharpened in the process.

So against my better judgment, I want to put forward to you an idea that I already know that many of you will disagree with out of hand: the unpopular argument that the EPA is right about all this.

Interesting things are afoot with the Environmental Protection Agency (EPA), as the governmental body is seemingly under the impression that it can regulate the modification of racing vehicles that were originally made for on-road use. As such, the EPA is looking to update legal language to solidify that opinion.

If granted, this would mean that any production-based racing series, both cars and motorcycles, would be subject to EPA emissions regulations, and as such aftermarket modification to those machines would be greatly reduced.

In essence, that sport bike that you take to the race track, whether or not it ever spins a wheel on the road, could be deemed illegal if you modify it from its EPA-certified form, i.e. add an exhaust, intake, etc. Needless to say, this is causing quite the stir.

For the 2016 model year, the MV Agusta Brutale 800 gets an obvious makeover, with changes coming to the tail section, fuel tank, exhaust, taillight, and LED headlight.

What is less obvious though, are the effects of having to be Euro4 emissions compliant, which drop the Brutale 800’s peak power from 125hp to 116hp, though there is an increase in peak torque, from 59 lbs•ft to 61 lbs•ft.

Judging by the amount of traffic the story is getting, we imagine the sight of the 2016 Ducati 959 Panigale at the EICMA show has ruffled a few feathers.

That’s understandable, since the Euro4 emission standards have forced the Italians to give the Ducati 959 Panigale an exhaust system that we’ve previously only seen on the Japanese-spec model of the Ducati 1199 Superbike.

While the shotgun exhaust isn’t as gawdy as one would think, it’s certainly a stark departure from the underslung units we are used to. We imagine it’s a moot point though, considering how many 959 Panigales will get some sort of slip-on or full-system exhaust from their new owners.

Just the same, the issue seems to be isolated to European soil, as the US-spec version of the 2016 Ducati 959 Panigale exhaust is just how we remember it. Check out the photos, after the jump, and compare it to the European-spec model (the first photo in the gallery).

That headline is a bit of a misnomer, since the new liquid-cooled Triumph Bonneville has been “spied” for some time now in the media.

Triumph is at least capable of admitting that its hipster machine is getting an update now, releasing this teaser video that hints at “something big” coming our way – if liquid-cooling an engine is something big, then we couldn’t agree more.

Ducati was all the talk of last week, after its Ducati 959 Panigale and Ducati Hypermotard 739 were outed in filings with the California Air Resources Board.

According to the CARB documents, the new “middleweight” Ducati sport bike is set to get a 955cc displacement increase, though we wondered what else would change.

Now we have a pretty good answer, as “spy photos” of the production machine are floating around the internet now, which show that the 959 Panigale is very similar in shape to the 899 Panigale it replaces.

A new Ducati Diavel has been caught by spy photographers, making this the first proper “leak” ahead of November’s EICMA show.

Though keeping the overall aesthetic of the Ducati Diavel in place, the model has some clear visual and mechanic differences. Namely, a belt drive…yes, you read that right.

Other changes include a feet-forward seating position, revised trellis chassis, and likely Ducati’s Testastretta DVT engine with variable valve technology.

The switch from Euro 3 to Euro 4 emissions standards at the end of 2016 almost assure the DVT engine permeating its way into Ducati’s current lineup.

If you believe everything you read on the internet, then surely you know that Ducati is allegedly getting ready to release a Panigale-based Streetfighter in the next few months. Another potent rumor making the rounds is that Ducati is working on a totally new v-twin engine, which will meet Euro 4 emission standards.

The first rumor got its start from Visordown, which says that it has received an invitation for press launch in September that will consist of “a track test for a road bike.”

The British publication deduces that the new model must be a sport-oriented machine to warrant the track time for journalists, and the only model in Ducati’s lineup that’s long-in-the-tooth that fits the bill is the Streetfighter 848, and the recently discontinued Streetfighter 1098.

The second rumor comes from Moto-Station, with the French site getting word from a source that Ducati has an all-new Euro 4 compliant engine that it will debut at EICMA this November. They go on to speculate that the engine could have Ducati Variable Timing (DVT), and would fit a sport-touring bike.

Let’s examine these two rumors a bit further, in turn.

Triumph seems set to debut four more variants of its Tiger 800, as CARB filings filings show a Tiger 800 XCA, Tiger 800 XCX, Tiger 800 XRT, and Tiger 800 XRX models for the 2015 model year. The news seems to show Triumph spreading out its middleweight ADV offering, giving on-road and off-road riders a bit more to choose from the British brand.

Helping us understand how Triumph sees the four added variants, Motorcycle.com has publish a chart (above), which Triumph sent to Tiger 800 owners as a part of its market research. That chart breaks down the various models’ spec, and which features that would come with as standard.

Noticeable across the board is that the three-cylinder gets a 15% MPG boost (the CARB document also show fewer hydrocarbon emissions), as well as ABS and traction control as standard features.

It looks like Suzuki is getting ready to update its sport bike offering, as Suzuki Motor America has gotten new emissions filings from the California Air Resources Board (CARB) for the 2015 Suzuki GSX-R600 and 2015 Suzuki GSX-R750.

New CARB emissions are required when manufacturers make modifications to the engines of the machines that they are selling in the Golden State, which means that we can expect updates for the Suzuki GSX-R600 & Suzuki GSX-R750 (with no change in CARB’s weird weight measurement figures, an entirely new model is unlikely).
