At the Sachsenring, after the introduction of KTM’s Moto3 GPR production racer, we spent five minutes with KTM’s Head of Motorsports Pit Beirer. We spoke to him about a number of subjects, including the evolution of the factory’s Moto3 chassis, the company’s cooperation with Kalex, and whether two-strokes would be better than four-strokes for racing.
The KTM Moto3 racer is a thing of beauty, and for bonus points, it comes in two varieties. One is the orange-trellis framed factory-built KTM, which will be campaigned by the three-rider factory team of Sandro Cortese, Danny Kent, and Arthur Sissis for 2012.
The other variety is the one engineered by Kalex Engineering, which features the same 250cc KTM motor as the factory version, but takes the German company’s prowess at chassis design, and uses a twin-spar aluminum frame instead of the factory team’s trellis variant. The venerable Team Aspar is one of the teams signed on to use the Kalex/KTM, and will have riders Alberto Moncayo & Hector Faubel aiming to beat the factory KTM squad at their own game.
With no Americans in Moto3, the entry-level GP series won’t get too much attention here in the US, but the machinery certainly looks pretty good to our eyes. Still clad in carbon fiber for the testing season, the KTM and KTM/Kalex machines are like tiny pieces of motorcycling art.
Though some are lamenting the passing of the two-stroke era, and its unmistakable buzzing sound on the track, we think the newest four-stroke GP class will please motorcycling’s audiophiles. Listen to the KTM Moto3 race bike warm up after the jump, and enjoy some eyecandy.
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).
Honda has finally given us an unshaded photo of its 250cc four-stroke Moto3 race bike, dubbed the Honda NSF250R. Despite the clearer view, there are no real surprises here (this actually looks like the same photo as used before, sans photoshopping), as the majority of the bike is still covered by the primer-painted fairing. Honda says the new NSF250R is designed to be like the RS125R it replaces: high-performaning, lightweight, and compact. This should make the switch from two to four-strokes easier for young riders, and limit the need to adjust riding styles for the new machine.
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.
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.
American youths can rejoice to the news that the 2011 Aprilia RS4 125 will be coming to the United States for 2011. The four-stroke 125cc beginner bike may only have 15hp, but it has been done-up to look like the RSV4, and that’s what matters right? Replacing the RS125, the RS4 125 is supposedly just a Derbi in sheep’s clothing, but considering both brands come from the Piaggio mother ship, we fail to see why that would be an issue to a 16-year-old who has somehow managed to convince his/her parents to buy them a motorcycle. The liquid-cooled, four-valve, DOHC motor comes with electric fuel-injection, and is mated to a six-speed gearbox. Weight is 264 lbs with a full 3.8 gallon tank of gas. Technical Specifications after the jump.
Honda has begun teasing its NRS250 race bike, which many believe will be the basis to the company’s involvement in the Moto3 racing class that will replace 125GP racing in 2012. NRS stands for “Next Racing Standard”, not to be confused with NSR series of two-stroke machines from Honda (Editor’s note: Great naming convention, right?), and not much is known about the bike beyond these dark photos.
Meeting this weekend, the GP Commission confirmed the demise of two-stroke GP racing as they finalized plans to start the Moto3 series in 2012. Replacing the 125GP racing class, Moto3 will center around 250cc singe-cylinder four-stroke motor with a maximum bore size of 81mm. The class will be open to multiple engine manufacturers, who will have to make their motors available for €10,000 or less.
