The front wheel's hydraulic drive motor is fitted in the wheel hub and connected to the wheel by a gear transmission.
The K&N; air filter is attached to a giant Mitsubishi TD04-HL turbo that's fed by a custom exhaust manifold.
Öhlins forks are complimented by a matching shock out back.
A Supertrapp muffler has the exhausting job of silencing the boosted motor.
Every so often someone builds a bike that's so different and radical it raises the bar: this R6 is just that-a game changer. At first glance it might seem like just a Euro-flavored streetfighter, but you'd be a fool to take it at face value.
Not only is this Yamaha rockin' a built motor and a turbo, but it's also two-wheel drive (2WD). Not one, but both wheels push and pull it down the road.
A bike of this caliber seems out of this world, but we can thank Mikael Tiainen of Emtes Engineering in Sweden for this one-of-a-kind monster.
"It took me roughly 7 months and over 600 hours to build the thing," Tiainen said. "Not only did I do all of the design work like the CAD and engineering, but I also fabricated most of the pieces myself," he added.
While the bike is little more than a shell of a stock R6, behind the custom pieces it's a 2003 model. Where most people build their customs around a literbike or bigger, Tiainen wanted to take the path less traveled.
"Building a turbo 600 is different, and making it 2WD is even crazier."
Taking the notion of crazy, the engine was punched to 620cc thanks to Wiseco forged 10:1 low-comp pistons that hang from Crower billet con-rods. Up top, the cylinder head received a full port and polish along with a special chamber treatment to compliment the forced induction.
Since the compression was dropped for boost, Tiainen decided to make up for the lack of cylinder pressure with a Mitsubishi TD04-HL turbocharger-a snail that coincidentally comes stock on 2.0 liter (that's 2000ccs for those counting) car engines.
Any gearhead knows a successful forced induction endeavor is far more than just a turbo, so Tiainen called upon a Haltech E6X for fuel injection and ignition duties while a PWM boost controller manipulates the wastegate. Taking it one step further, an air-to-water intercooler was tucked inside the tail to curb escalating intake temps. The custom cooler uses a Laminoca watercooled core for the heat exchanger.
With big steam underfoot it only made sense that Tiainen would set out on a serious search for traction. But nobody could have guessed what his solution would eventually be.
"I decided to utilize the Öhlins 2WD system because it's an engineering marvel and not many people have used it."
Like something from a James Bond flick, the Öhlins 2WD system is out of this world, as it actually drives both wheels. By connecting two identical hydraulic pumps, one at the countershaft sprocket and one at the front wheel, engineers were able to create a system that varies the torque output. In other words, when the velocities of the front and rear wheels are the same, very little torque is applied to the front wheel. However, when the rear wheel starts to spin, torque is transferred to the front wheel in hopes of increasing overall grip.
Better yet, the entire system weighs under 20 pounds and is said to aid in everything from standing start acceleration tests to wheelies (the front wheel will continue to spin at the rate of the rear). With all that grip this R6 would surely lay the smack down at the strip.
But for any penny pinchers with grandiose dreams of a 2WD system on their own streetbike, the Öhlins kit retails north of $10,000.
As you'd expect, neither the custom turbo kit nor the 2WD retrofit was a bolt-on affair. "It took a lot of work and help from my engineering friends at Öhlins and ISR-Brakes to make it work," Tiainen said. "Marchesini even had to custom fabricate me a front wheel to make it work with the 2WD system."
But more than just an expensive paperweight, when the boosted badass was finally on the road, Öhlins test engineers put it to the test around a racetrack. Needless to say, the go-fast techno weenies were blown away at the hellacious amounts of grip offset by the wild turbocharged acceleration. As if that's not cool enough, Tiainen mentioned that he once took his R6 for a high-speed run down the beach. Imagne trying that on a stock R6. "Out on the harder sand by the water's edge I was able to pin it through the gears and let it fly. Considering it was on street tires and spinning both of them at over 100 mph, I'd say a stock bike would have just gotten stuck."
Without question this is one of the wickedest, most unassuming R6s we've ever seen. So the next time someone tells you their Yamaha is hooked up, ask them if its got a built motor, a custom intercooled turbo, 2WD and is capable of 100 mph blasts in the sand.
