Just a couple ticks off the KTM RC250GP raced in the FIM Moto3 Championship that we saw built in time-lapse last week, the KTM RC250R is perhaps one of the most potent 250cc four-stroke production racers money can buy…and it takes a lot of money to buy one.

“The differences [between the RC250GP & RC250R] come through some little details,” says Head of KTM Customer Racing Wolfgang Felber. ”The GP bike for example runs with the regulation enforced Dell’Orto electronics unit, has a different Akrapovic exhaust system, magnesium wheels, and modified brakes as well as WP factory suspension parts, which help to save some more weight.”

Only 67 of these machines will be made for the 2013 season (40 for sale, 27 for the Red Bull Rookies Cup), which posed a problem for the KTM. Too big of a production run to be hand-made by racing engineers, and yet too small (and perhaps too important) of a run to be built on one of the four general assembly lines, zie Austrians instead opted for something in between, and built the bikes on the company’s #5 “training” line.

A behind the scenes look at this limited production run, if you weren’t in love with the KTM Moto3 race bike, you might be after this. Want one? You better come up with €45,000 to afford this price tag…that’s $60,000, or a moderately equipped Mercedes-Benz E-Class, with today’s exchange rate.

Condensing three days into just three minutes, KTM has a nice timelapse video for us that shows the complete build-up of two 2013 KTM RC250GP Moto3 race bikes for the Ajo Team — the same bikes that would go on to dominate the the Moto3 test at Valencia earlier this month.

While the 2013 version of the KTM RC250GP may look similar to its predecessor, KTM has in fact made many changes to the 250cc race bike.

“Basically the 2013 KTM RC250GP is a completely new bike. The only things that have not been changed are the rear swingarm unit and the wheels,” says Wolfgang Felber, KTM Engineer and Road Racing Senior Manager.

“All other components have been modified or bettered: frame, fork, tank, airbox, exhaust etc. Several parts have been simplified because the bike could be 3 to 4 kilos lighter. The engine received only marginal treatment because last year it already turned out to be very powerful and reliable as well. So power is up only a little.”

The long wait of so many MotoGP fans is nearly over. The 2013 MotoGP season is about to get underway, or rather, the phony war of testing, which is the first step on the road to the 2013 MotoGP season. In just a few hours’ time, the howl of the CRT machines will fill the grandstands at Sepang, joined two days later by the roar of the MotoGP prototypes.

The CRT machines have two extra days of testing ahead of the full test at Sepang, where the teams will have their first chance to test the new spec Magneti Marelli electronics system on track, after having first dialed the system on the dyno at their respective bases.

The system will be used by all of the CRT teams ,except for those running the Aprilia ART bikes, and so far, the reaction has been very positive to the capabilities of the system. This should come as no surprise, given that Magneti Marelli is the de facto standard in the MotoGP paddock, already in use by both Yamaha and Ducati, though both factories run their own custom software.

This is part 1 of a new series entitled ‘Under the Radar’. In it, we will be looking at stories we believe will have a major impact on MotoGP and World Superbikes in the next season, but which are not currently receiving much attention. While everyone expects Marc Marquez in MotoGP to be a big story, or Valentino Rossi’s return to Yamaha, these are the stories which you won’t hear much about by the start of the season, but which could end up playing a major role in 2013.

Everyone can guess the big names that are likely to make an impact in MotoGP in 2013: Marc Marquez will clearly be an exciting rookie to watch, Valentino Rossi should be competitive on a Yamaha, Pol Espargaro looks set to dominate Moto2, and Maverick Viñales and Luis Salom will be major players in Moto3. But look beyond the obvious candidates, and there are a number of candidates who could cause a surprise in 2013. Here are some of the riders to watch this season.

For some time now, we have known that KTM intended to bring a 300cc-class version of its KTM 125 Duke motorcycle to market, thanks primarily to a leaked product road map that covered the Austrian company’s product line-up clear through the 2014 model year.

Slotted to bring the KTM 390 Duke to the US market this coming spring, the leaked road map has so far proven to be accurate, and has two interesting machines listed for 2014: the KTM Moto3 350 & KTM Enduro 350.

Now confirmed by KTM’s CEO Stefan Pierer, KTM will debut a “faired” model (the KTM Moto3 350) and a “travel” model (KTM Enduro 350), which are based off the KTM 390 Duke platform, and will share the bike’s 375cc single-cylinder engine.

It’s easy to forget that motorcycle racing is a sport for children. Their courage on track is remarkable, and even more so because of their young age. They start at five, four, sometimes three, riding their tiny motorbikes around the paddock or on dirt tracks in rural towns and lonely desert spaces and sometimes in organized series such as the Cuna Campeones Bankia.

At this moment there are thousands of kids either on their little machines or wishing they were riding, counting the minutes until they get to put the helmet back on and ride, perhaps just for the joy or perhaps with dreams of a world championship.

They have various levels of support from adults, ranging from the tolerant, to the indulging, to the demanding. As in all endeavors, most of the individuals either don’t reach their potential due to other demands on their time, energy or budget, or they approach that potential, and are judged to have too little talent in their bodies and minds to warrant moving to the next level.

Those who have the talent and desire, and are lucky enough to be recognized as such, might receive the support to compete at higher and higher levels. And sometimes by the onset of adolescence these kids are worldly and experienced in the ways of competition, travel, sponsorship, and so on.

Two freshly anointed champions, three impressive winners, and a large crowd of ecstatic and yet wistful fans, come to say goodbye to a departing hero and hope to spot a new one arriving. Even the weather cooperated. That’s how good the Australian Grand Prix was at Phillip Island this year. All three races were a lot less intense than the previous two weekends, but even that didn’t matter, because of the manner in which the winners secured their victories, and because the Australian crowd had something to cheer about in all three categories.

It started in the Moto3 race, where Sandro Cortese rode one of his best races of the year, the title he clinched last weekend at Sepang clearly a weight off his mind, allowing the young German to ride freely. He had Miguel Oliveira to contend with for most of the race, but in the end, he would not be denied. The home crowd still had much to cheer about, as local boy Arthur Sissis, the 17-year-old former Red Bull Rookie, won an intense battle for third, putting an Australian on the podium for the first time on Sunday.

In Moto2, Pol Espargaro gave a display of dominance rarely seen in the intensively competitive class. It was hardly unexpected, Espargaro having stamped his authority on practice for the past two days, but the style in which the Spaniard won was very, very impressive. It took him a couple of laps to get past Marc Marquez and Takaaki Nakagami, but once he did, he put a second or more a lap on most of the field, before cruising home to a spectacular victory. Espargaro could do nothing to prevent Marquez becoming champion, concentrating solely on the task ahead, winning as many races as possible.

The home crowd had something to cheer for as well, Ant West riding an outstanding race to hold off a late charge from Marc Marquez to secure second place, making it two podiums in a row. West’s podium at Sepang last weekend took the weight of the Australian veteran’s shoulders and has given him the confidence boost he needed.

The team have been making slow progress, West had said earlier this weekend, and Sepang was the reward from that hard work. Most of all, though, it had helped him find his belief in himself again; that alone is worth half a second or more a lap. At this level, motorcycle racing is 90% mental.

Marquez finished third, but still took the 2012 Moto2 title with honor. He may not have been able to win – no one had the measure of Espargaro at Phillip Island – but he gave an impressive account of himself and secured the championship with a podium. Marquez is a deserved winner of the championship, despite the criticism sometimes aimed at the young Spaniard. The onboard video of the first lap at Motegi shows one of the most compelling displays of courage, skill and racing sense of recent years, and justifies on its own his ascension to the premier class next season.

There has been much made of Marquez’ backing and support, and of the special treatment he has received. It is true that he has had solid sponsorship and always been in a strong team, but the reason why he has had the backing is because of his extraordinary talent, rather than the other way around. A MotoGP team manager who was at the test where Marquez took his first laps on a Moto2 machine was in awe: “He is a very special talent.”

Winning the title on what is a very ordinary chassis – the massive success of the Kalex bikes compared to the mediocre results of the other Suters – speaks volumes about the ability of Marquez, and the Spaniard will be very fast from the very first MotoGP race at Qatar. HRC boss Shuhei Nakamoto has already said that he expects Marquez to be on the podium at that race; it would not surprise me in the slightest.

The main course, however, was the demonstration to be given by Casey Stoner in the MotoGP class. Stoner had almost humiliated the rest of the field during practice, consistently half a second or more quicker than anyone else, the gap often closer to a second. At a track where the lap is usually 90 seconds, that is a massive advantage.

The Grand Prix Circus came to Sepang with three titles in the balance. Only one of them got wrapped up on Sunday, though, tropical rainstorms throwing a spanner into the works of the other two, but generating some fascinating racing. The fans had one fantastic dry race, one fantastic wet race, and a processional MotoGP race that looked much the same as it would have had it been dry.

There was a packed house – over 77,000 people crowded into the circuit, a highly respectable number for a flyaway round – cheering on local heroes, there was confusion over the rules, and there were a lot of new faces on the podium.

There was also a much better balance of nationalities on the podium: where in previous races, the Spanish national anthem has been played three times on a Sunday, at Sepang, it was only heard once. Most of all, though, the Moto2 and MotoGP races ran in the wet would be determined by the timing of the red flags, with Race Direction’s decisions on safety also having an outcome on the results of the races, and in the case of MotoGP, possibly implications for the championship.

This year’s Malaysian round of the MotoGP series has offered a glimpse of the future, for those with an interest in seeing it. While the series is locked in a series of arguments over the future of the technical regulations, the massive economic problems in its key television markets, and the Spanish domination of the sport in all classes, Sepang pointed the way forward, and that way is definitely east.

It starts with the crowds. Where crowd numbers have been falling almost everywhere at the European rounds, Sepang is seeing record attendances this weekend. Grandstand tickets are selling out fast, and despite the rain, fans are turning up in large numbers.

How much those numbers are being inflated by Australians flocking to the circuits they can fly to affordably to see Casey Stoner ride the last few races of his career is uncertain, but that they should be packing the grandstands in Malaysia seems unlikely. There are also plenty of local fans, coming to see riders from the region threaten the top of the time sheets for the first time in history, and not just make up the numbers at the rear.

They have had a treat this weekend. On Friday, local wildcard Hafizh Syahrin topped an admittedly wet session of Moto2 free practice by getting out early when it was relatively dry, but he had sufficient competition for his result to have been noteworthy.

On Saturday morning, Japanese rider Takaaki Nakagami topped Moto2 FP3, once again by judging the conditions correctly. And on Saturday afternoon, the fans were in for a massive treat, when Zulfahmi Khairuddin bagged his first ever pole position in front of his home crowd, becoming the first ever Malaysian to start from pole in a Grand Prix. And on his 21st birthday too.

It was a strange day in Malaysia. Part of the strangeness was down to the weather. The familiar pattern of disrupted sessions as the rain fell, but not hard enough to allow the MotoGP riders, in particular, to spend much time on the track in the afternoon.

There was a twist, however, a particularly Malaysian one at Sepang: the heavy shower which passed over the track at the start of the afternoon session for MotoGP left part of the circuit soaking, with water a couple of centimeters deep at turns 1 and 2, while the rest of the circuit quickly dried out almost completely. It at least added a little novelty to the disruption, along with the frustration of another wasted practice.

The real strangeness came at the start of the day, however. It took about 10 minutes for observers to notice that Maverick Viñales had not gone out on track and there was suspiciously little activity in the Avintia Blusens garage. Once they noticed, low-level pandemonium broke out: within seconds, a throng of Spanish journalists crowded out of the media center and hastened on their way into the paddock, to find anyone and everyone and learn what they could.

As they drifted back in, and as TV pictures started to appear showing an empty Blusens garage, Viñales walking through the paddock accompanied by his father and the Dorna media officer, and team managers Raul Romero and Ricard Jové gathered in discussions, it was clear that there was something very wrong.

When it was revealed what that was – that Viñales had decided to quit the team with immediate effect – it sent a shockwave through the paddock. Riders quitting teams with races left in the championship is unusual; to do it while that rider is second in the title chase and still in with a shot at the championship is unheard of in motorsport.
