According to the Indonesian publication TMC Blog, Kawasaki is working on a performance-oriented 250cc four-cylinder…and they have the supposed photos to prove it. The news should be well-received by those who remember the high-revving small-displacement Japanese machines of just a few decades ago.

Southeast Asian markets, like Indonesia’s, are driven by graduated taxes on motorcycle displacement. For the Indonesian market, machines 250cc to 500cc in displacement receive a 60% tax rate, while machine over 500cc are taxed at 75%. Unsurprisingly then, bikes under 250cc are accounting for the lion’s share of motorcycle sales.

Working against that taxation plan is the growing middle class in these regions, with consumers able to purchase more expensive motorbikes, and looking for more performance in the process. This trend is what helped bring the Yamaha R25 to market (and production) in Indonesia, along with the slew of other ~250cc machines we’ve seen from Honda, Kawasaki, and KTM.

Head of Ducati Corse, Filippo Preziosi is a busy man under regular circumstances, and with the shenanigans going on in Ducati Corse’s MotoGP team right now, the former motorcycle racer is a hard man to get a word with, let alone on a race weekend in Brno. Somehow catching up with Preziosi during MotoGP’s Brno test, our friend David Emmett at MotoMatters, along with several other journalists, sat down with Ducati’s Maestro of MotoGP to ask him about where the Italian team was headed, and the challenges it is currently facing.

There is of course a tremendous amount of chatter going on in the MotoGP paddock about Ducati’s “frameless” carbon fiber chassis, a switch to an aluminum twin-spar frame, the Bridgestone tires, and Valentino Rossi’s psyche, all of which Emmett has already summarized for us in his detailed analysis of Ducati Corse’s situation. Taking on all of these issues, Preziosi sheds some insight on what is going on behind the scenes at Ducati, and is candid about what issues they are and are not facing.

Dismissing out right that the “L” engine configuration is at least partially to blame for Desmosedici’s lack of front-end feel, one of the more interesting points Preziosi makes is his preference for the v-twin motor. Acknowledging that the package will perhaps make less power/torque than a four-cylinder, Preziosi opts for instead the two-cylinder’s rideability, and if the rules allowed it, the motor’s weight advantage over the inlines (this of course coming from a man who has figured out how to make a v-twin without the weight of a traditional frame).

His comments raise some interesting thoughts about the way rules are constructed in motorcycle racing classes, and perhaps speaks to the central issue occurring MotoGP: that the rules are pigeonholing the development of GP motorcycles into one particular slot, that just happens to be a four-cylinder motorcycle with a conventional frame that reacts to a prescribed tire construction methodology. Preziosi makes some other interesting comments that read well between the lines, check them out in transcribed interview after the jump.
