Suck, squeeze, bang, and blow – there is no way to more succinctly describe the combustion process of a four-stroke engine. If you are more of a visual learner though, we might have the perfect video series to show the combustion process in your typical road-going motorcycle.

The video comes courtesy of the “Warped Perception” channel on YouTube, which has made a name for itself by taking high-speed high-resolution cameras and using them to show and explain complex actions.

In the case here, Warped Perception took a 3hp Briggs & Stratton engine, removed the head and replaced it with about an inch of acrylic glass, and then proceeded to see what would and would not burn in the simple engine design.

Slowing things down to 4,000 frames per second, and shooting 4k video, we get an absolutely stunning, not to mention informative, perspective of what happens in your typical internal combustion engine. Enjoy!

The rise of electronic rider aids has come to consumer-level dirt bikes, with Husqvarna now offering traction control on all of its four-stroke motocross motorcycles for the 2017 model year.

Traction control on dirt bikes isn’t a new concept, with racing machines featuring the technology for almost a decade now (in some form or another, and depsite what the rules say), but Husqvarna’s foray into the use of electronics marks a new era for consumer dirt bikes.

As we see already in the on-road segments, traction control and other electronics are proving themselves to be the new horsepower. Their introduction into the off-road realm was all but assured (and started with the 2015 Kawasaki KX450F), and now that day has seemingly come for the masses.

Fresh from the office of the USPTO, we have confirmation that Honda has just received the patent for the first ever three-stroke motorcycle engine.

As you would expect, the unconventional engine design incorporates the power-to-displacement efficiencies of a two-stroke smoker, with fuel-to-power efficiencies of a four-stroke motor.

For many in the space, the three-stroke engine has been the Holy Grail of engine designs, with many OEMs rumored to have been working on a three-stroke engine.

Still, it is surprising to see the engineers at Honda claim the prize, as the Japanese brand up until recently has been heavily committed to its four-stroke technology.

Obviously, the engine technology can obviously be applied to any internal combustion application, however what makes this news especially A&R worthy is that Honda’s patent specifically states the engine’s purpose in two-wheeled vehicles, watercraft, lawnmowers, and generators.

It was nearly a month ago that we heard that Spanish firms Gas Gas and Ossa had merged their operations in order to take on the difficult economic climate in Spain. The firms’ business position should be even stronger now, as Gas Gas has acquired the IP from Moto Italia, the holding company of Husqvarna’s remains.

When KTM’s Stefan Pierer acquired Husqvarna through his Pierer Industrie AG company, he did not buy all of the once Swedish motorcycle brand from BMW Motorrad. What wasn’t transferred into the Austrian company’s control was left behind as a new company, Moto Italia, which now will find a new home in Spain with Gas Gas.

For the past twenty years or so, there is one manufacturer who has been above all others in the premier class of grand prix motorcycle racing, and that manufacturer is Honda.

Winning 12 of the last 20 World Championship titles, Honda’s recent domination in 500GP and MotoGP has been a sea change for the series, and the company’s winning total in this modern era of four-stroke and two-stroke machines is double the next nearest OEM, Yamaha (MV Agusta still holds the outright record, with 18 championships from the 1956-1974 period of four-stroke racing).

Part of Honda’s success has been the fact that the Japanese motorcycle manufacturer has been able to attract some of the best riders ever to come to a Grand Prix race’s starting line, champions like Mick Doohan (1994-1998), Àlex Crivillé (1999), Valentino Rossi (2001-2003), Nicky Hayden (2006), Casey Stoner (2011), and now Marc Marquez (2013).

But also part of the equation has been the superb equipment that HRC, Honda’s racing department, produces for its riders, bike likes the Honda NSR500, RC211v, RC212V, and RC213V, which have widely been regarded as the best machines on the grid in each of their respective eras.

Looking down the pipe, as MotoGP adopts new rules and regulations, the RC213V and RCV1000R appear set to dominate their respective classes as the factory machines will be reduced to 20 liters of fuel for next year, and the open class machines are forced to use both the Dorna-supplied ECU hardware and software.

It would appear that Honda has a firm grasp on the next few years of MotoGP racing, and as a bit of an homage to this company’s fantastic two-wheeled craftsmanship, along with the racers who rode them, we give you wallpaper-sized photos of Honda’s Grand Prix motorcycles, from the 1995 to 2013 seasons.

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.
