Last week we brought you a report that said that the Kawasaki Ninja ZX-25R made over 40hp at the wheel at a recent dyno test.

The report attributed no source, which made that horsepower claim a bit hard to verify, but today we seem to have found where that power figure came from, thanks to our friends in Indonesia at the TMC Blog.

Slovenian exhaust maker Akrapovič briefly listed the Kawasaki Ninja ZX-25R on its website, showing both the stock horsepower and torque figures for the quarter-liter four-cylinder monster, but also the gains made from the company’s racing exhaust line.

There is quite a lot of buzz going on right now regarding KTM's upcoming 490 series of motorcycles - some of it is new information coming to the light, but most of it just rehashing old stories to fill in a dearth of headlines.

So, we figure we would sort wheat from chaff, and share everything we know and suspect so far from KTM's next engine platform, and put it into one place for our A&R Pro subscribers.

Good news if you are a small-displacement racing fan, as the Aprilia RS250 SP will not just be a European affair, as we get word today that the 250cc track bike will be coming to the USA as well. 

Interestingly enough, the Aprilia RS250 SP will not make its way across the pond via the Piaggio Group, but instead Rise Moto – the Ohvale distributer for the United States – will be importing the machine.

That shouldn’t be too much of a surprise for those who are in the loop on how the Aprilia RS250 SP came to be (and of course you are, as you religiously read Asphalt & Rubber every day).

It is surprising to us that Kawasaki has been so tight-lipped about its upcoming Ninja ZX-25R model.

It is not like the Japanese brand has been shy about talking about the Kawasaki Ninja ZX-25R, instead they just don’t seem to want to say anything of substance about the machine.

Maybe it is because we already know the most important aspect about the ZX-25R – namely that it has a 250cc four-cylinder engine that revs to the moon, along with traction control and other go-fast electronics.

This little gem, the Nito N4, has been burning a hole in our to-do list for far too long, ever since we saw it at the EICMA show in Milan last year. It’s not a big fancy superbike, and it’s not even a proper supermoto.

Instead, the 15hp Nito N4 is just an attractive people-mover that extends the Italian brand’s offering of urban-use two-wheelers.

On that vein, Nito says that the N4 is good for over 90 miles of range, can reach a top speed of 90 mph (150 km/h), and tips the scales at 385 lbs.

If you are looking for a pint-sized adventure-bike, and the BMW G310GS doesn’t slick your hair back, then the KTM 390 Adventure is surely something you have been following.

If that is the case, then you have been following the development of this bike for quite some time, with it taking the Austrian brand just over 6 years to get this bike to market.

But, the KTM 390 Adventure is finally ready for delivery, and in May 2020 it will land at American dealerships, with a price tag of $6,199 MSRP.

Last week, we brought you photos of a carbon fiber clad Kawasaki Ninja ZX-25R race bike that was put together by the Japanese brand to help promote the model’s launch, and to give an idea of what to expect from their upcoming spec-series for the quarter-liter screamer.

You liked it. We liked it. The motorcycling internet liked it. And let’s be honest, what isn’t their to like about this new motorcycle when its dripping in go-fast parts and ready to do the thing on any race track you point it at?

Feeling the need for an encore, Kawasaki has released some more photos of its carbon fiber ZX-25R, and naturally we feel obliged to share them with you.

Today is a twofer for the Kawasaki Ninja ZX-25R, as we get word from Southeast Asia that the bike’s debut this week has been postponed because of worries about spreading the coronavirus, which means we have to wait just a little longer to find out everything about this 250cc four-cylinder wonder.

On the bright side though, Team Green has posted up this unique carbon fiber creation, which it calls the Kawasaki Ninja ZX-25R Racer Custom model. As the name implies, it is a carbon-fiber-everything version of the ZX-25R, that is track-only.

The Kawasaki Ninja ZX-25R is a bike that we are eagerly looking forward to, here at Asphalt & Rubber, which might seem strange if you don’t know too much about the quarter-liter sport bike.

But with a 250cc displacement coming from its inline-four engine, which revs to 17,000 rpm…well, the Kawasaki Ninja ZX-25R isn’t your typical mundane small-displacement affair.

Team Green is slowly building the hype machine for this model, and to help get us in the mood, we have a short video of WorldSBK racers Jonathan Rea and Alex Lowes putting the ZX-25R through its paces at the Jerez circuit.

For the 2020 racing year, MotoAmerica has announced that it will run a three-round Mini Cup, in an effort to bridge the gap for young racers into professional racing.

The new series, which will race at Road America, The Ridge Motorsports Park, and PittRace, will have four spec-classes, all of which will use Ohvale motorcycles.

The class breakdown is as follow: 110cc (four-speed); 160cc; 190cc (racers aged up to 14 years); and 190 Adult (racers over the age of 15), with all of the races set to take place on karting tracks at the aforementioned race courses.
