KTM has announced it will be entering the Moto3 Championship, building a 250cc single-cylinder bike in what the company is describing as an 100% in-house operation. This statement is a bit confusing though, as KTM will also be partnering with Kalex Engineering on a second bike, where KTM will help the German company by supplying their race motors. No riders have been confirmed on either the KTM or KTM/Kalex machines.

KTM’s return to international road racing is certainly a welcomed sight, and it’s interesting that the Austrian company is both building its own bike, and supplying motors to other outfits. Both the KTM and KTM/Kalex machines will have to compete against the Honda NSF250R race bike, which Honda debuted at the Catalan GP just yesterday.

Honda has done a pretty good job of teasing out its HRC NSF250R, which is set to race in the Moto3 Championship in 2012. Replacing the 125GP, Moto3 class is based around four-stroke 250cc race bikes, and should be a more affordable and leveling playing field for new riders to enter into GP racing. HRC has teased us with images and videos of the new NSF250R, which takes its core cues from the its RS125R predecessor (both current factory Honda riders Dani Pedrosa and Andrea Dovizioso won their lower Championships on the Honda RS125R).

At the end of last year we learned that KTM had committed itself internally to competing in the upcoming Moto3 class, which is slated to replace 125GP in 2012. At the time of that news, the Austrian company was still in the early stages of planning for its 250cc four-stroke single-cylinder race bike; but not wanting to let Honda take all of the Moto3 development spotlight with its NRS 250, this past week KTM began testing Moto3 chassis configuration at the Cartagena track in Spain.

Arriving with a modified 125cc chassis and 350cc SX-F thumper, KTM’s IDM Supersport rider Michi Ranseder took to the helm of the prototype race machine over the two day testing session. More of a prologue than the first chapter to KTM’s Moto3 story, this event makes it clear that KTM is still getting its bearings on what direction it wants to take its entry-level GP program.

Perhaps as a belated holiday treat, Honda has finally seen it fit to give a better glimpse of its HRC NRS 250 Moto3 contender. With a few quick cuts and some blurry shots, HRC isn’t completely giving away the 250cc single-cylinder GP bike, but the footage does give us a better idea of what the final shape of the Honda will look like, and perhaps more importantly what it will sound like. If you’re a four-stroke fan, you’ll love the video after the jump…two-stroke fanatics, probably not as much.

With the demise of 125GP coming down the pipe, it comes as no surprise today that we learn that KTM has begun working on a Moto3 racing program. According to GPOne, work began on the project a few weeks ago, and is still in the early stages of its design. With all the 250cc MX, enduro, and supermoto four-stroke singles in KTM’s arsenal, the Austrian company has a surfeit of experience in making potent small displacement machines, and could be an early favorite in the 2012 opening season. The news also balances out well with the recent confirmation that KTM is working on a 250cc+ version of its KTM 125 Duke, which is destined for the American market in the next 18 months or so.

Perhaps our only gripe with the 2011 KTM 125 Duke (besides of course that it’s not coming to America), is the too small for American roads 125cc displacement. With no graduated licensing programs to be found, unlike our European brethren, the 125cc learner format just doesn’t seem to work in our “can travel anywhere by car” society here in the United States. Not to fret says KTM though, as a 250cc or even 300cc version of the orange pocket rocket is under development at the Austrian company.

We think 250cc/300cc would be an ideal size for blasting from stoplight to stoplight on city streets, both for new riders and veteran hooligans alike, and it won’t take much to place the outwardly similarly sized motor in the KTM 125 Duke frame. Thinking along those same veins, KTM says an 18 month trail time is expected from the 125 Duke launch to when we’ll see the next larger iteration.

The guys at Bakker have been busy this year, first bringing us a re-imagining of the Suzuki TL1000R, and now a turnkey Moto3 class contender. Noting that two-stroke race bikes are going the way of the dinosaur, the master frame builders at Bakker set out to make a four-stroke package that would fit into MotoGP’s Moto3 series and other 250cc single-cylinder racing classes.

Able to accomodate any manufacturer’s motor, Bakker has a Suzuki-powered model (the Bakker RM-Z250R) that’s been proven in the Open Dutch Championship (ONK) 125cc, the German IDM 125cc, and the UEM Supermono Cup. The Dutch company also has a Honda-powered unit that is ready to go for Moto3 competition when the rules switch in 2012.

Honda continues to taunt us with its upcoming Moto3 contender, the Honda NRS 250. Shedding some more light (that would be literally, not figuratively), on the 250cc four-stroke GP racer, Honda still hasn’t released any details on the machine, but you can expect an 81mm bore and a maximum weight (with rider) of 326 lbs, per the Moto3 regulations that were recently released. Moto3 is scheduled to replace 125GP racing in 2012, but we imagine Honda will divulge info on the NRS 250 well before then. The original and super-enhanced photos of the Honda NRS 250 are after the jump.

Announced at Valencia this weekend, the GP Commission has finally released the details on the upcoming Moto3 class, which will replace 125GP racing in 2012. Based around a four-stroke 250cc single-cylinder motor with an 81mm maximum bore size, Moto3 aims to reel in the spiraling costs of GP racing, with numerous provisions that are designed to limit how much money teams and manufacturers can sink into the sport to buy victory.

Perhaps the biggest provision designed to help lower the cost of GP racing’s intro class is the spec-ECU rule, which sees teams limited on the level of electronics they can implement, and institutes a hard-cap on the engine’s maximum RPM (14,000 RPM). With multiple manufacturers able to offer motors and chassis for the racing class, Moto3 should be more open thatn the single-motor Moto2 series. The GP Commission has included a laundry list of other provisions, you can find them bullet-pointed after the jump.

Do not adjust your computer screen, this not a revised version of the VFR1200F, nor is it the V4 adventure bike we expect Honda to debut next week, it’s not even the bastard love child from a CBR and a Cylon, it is in fact the brand new 2011 Honda CBR250R. A 250cc motorcycle for the rest of us, Honda hopes to snag new riders by offering a more practical street bike in the Japanese, European, Australian, and yes, even American markets later this spring.

Raising the bar a bit, the CBR250R comes with optional C-ABS brakes, which will like be mandatory in the European Union, if the EU Commission has anything to say about it. With performance figures coming in at 26hp and 17 lbs•ft of torque, the fuel-injected Honda CBR250R isn’t going to blow anyone out of the water, but that’s sort the point behind the quarter-liter bike, which should be more than capable of scooting around a young rider on city streets and back-road routes.
