Yamaha set to launch hybrid motorcycle for 2010

Yamaha set to hybrid production motorcycle for

Back in 2005, Yamaha the wacky 2005 Gen-Ryu concept bike at the Tokyo Show amidst a raft of very non-conventional two wheelers as the aptly named FC-Me cell bike. the ingenious elec tric reconfigurable the Chivicker, Passol and the Maxam limousine. Now it appears certain the will become a showroom in 2010.

A series of patent detail the new motorcycle which the YZF-R6 600cc engine to a generator which in turn the rear wheel. History that every Yamaha patent published over the 20 years has resulted in a full machine, so there’s little this one is also heading for a near you in the very near You can expect to see it in the flesh for the first at the Tokyo Motor Show this year.

Proving the idea of hybrids – machines combine both petrol and electric motors – are soon to a widespread idea, Yamaha’s machine looks set to steal the from rivals at Honda, has also announced it will be a production hybrid next

While rumours and earlier all suggest that the Honda will be a resolutely practical hiding its glamorous technology a conventional-looking skin, the new Yamaha its inspiration from the firm’s 2005 Gen-Ryu concept

That bike, revealed at the Motor Show four ago, combined the inline engine from the firm’s with a massive generator and motor. Instead of using the to directly drive the rear its main use was to turn the generator, in turn provided all the power the motor could need to sportsbike-style performance using a drive to the rear wheel. electric power, there’s no for a clutch or gearbox, and their goes some way to offsetting the weight of the electric motor and

The Japanese word Gen-Ryu translates to ‘source of the river’, and all eyes turning to electric and power, it could be soon be a torrent.

And this, the first production hybrid, is the first of that. As usual when a is translated to reality, some of the Gen-Ryu’s key points have toned down, both in terms and on the styling front, there’s no way the new machine could be termed ‘conservative’.

The most loss is the 600cc, four-cylinder R6 swapped instead for a much and significantly smaller, single-cylinder probably in the region of 250cc. But be disheartened – the bike’s peak depends not on the petrol engine but the motor and batteries, so while the might be small that mean the bike’s performance be disappointing.

Just like the Gen-Ryu concept, the new production styling is dominated by a pair of plate-sized circular covers, one on side of the bike, carrying a design which looks set to a key styling feature for all Yamaha’s machines. These are more mere styling fancies, as they house the key ingredients of the new

The right hand cover the massive generator which the petrol engine’s power electricity, while the left unit comprises a similarly electric motor. Both are to the ends of a two-piece shaft runs transversely behind the at the centre of which lies the biggest secret, a planetary unit that attaches the main components – the petrol electric motor, generator and chain to the rear wheel – to almost unlimited flexibility in the way the transmits its power to the road.

how it works:the bike uses a array of ring gear, gears and a sun gear to combine the two units. The Ring gear is to the electric motor via a clutch and attached via a chain to reduction and the rear wheel. The four gears are mounted on a disc by the petrol engine and the Sun gear is directly to the generator.

Ring gear stationary = stationary

When the electric isn’t running but the petrol is, the planetary gears can transmit all its to the generator to charge the batteries. If the are fully charged, the petrol will stop. The bike away using electric only, with the petrol cutting-in when needed.

gear turning = bike

The ring gear, and hence the drive, can be driven by just engine via the planetary gears, the electric motor disengaged. By the speed of the sun gear attached to the the speed of the planetary gears is with that the ring output speed varies, a continuously variable transmission. The the sun gear goes, the faster the gear turns as a result of the gears turning faster.

At low more of the engine power is to the generator, spinning the sun gear

It can also operate just on motor,with the petrol engine This stops the planetary disc from turning, but the gears allow the outer and therefore the output sprocket, to

On a closed throttle, or under the electric motor becomes a generator, regenerating power and it back to the battery pack.

it can operate with both motor and petrol engine using a combination of the two modes giving maximum power, the full output of both the engine and the electric motor transmitted to the output sprocket and the wheel.

It sounds complicated, but in it’s a solution that complete flexibility, allowing any combination of petrol and electric to be used, with a very transmission using a minimal of components.

The final drive is via a set of reduction gears mounted the engine, and finally by a twin drive, further reducing the of the rear wheel and multiplying the

As you’d expect with a engine, generator and electric to juggle, a vast amount of the control is taken over by the computer. To ride, the new machine to be a paragon of simplicity. Twist the to go, grab the brake to stop.

The will judge whether to use electric, just petrol or a of the two – all the rider should know it is that the amount of twist he to the throttle is turned into a increase in power.

The original wild looks meant it the ‘will it or won’t it’ speculation surrounding most bikes – onlookers simply it was eye-candy to attract showgoers to the stand at the 2005 Tokyo Show. And predictably it’s toned down significantly to a production-ready machine.

Gone is the hub-centre-steered front suspension, by conventional forks, while the excesses of the all-enveloping bodywork been cut back – the production is shorter, taller and more in appearance, although it’s nothing like a ‘normal’ The original LED headlights are replaced by a single lamp, hidden a steeply-sloping panel that the shape of the original concept’s The rear lights are also derived from the Gen-Ryu

While it’s much upright, the stand-alone windscreen – on support brackets sprouting the top yoke – is also mirrored in the concept, as are the long, wide with no need for any foot the rider can put his feet anywhere the boards.

Overall, the looks be beautiful, but despite the watering for production the overall effect manages to looks suitably without plumbing the depths of represented by Honda’s DN-01, the new machine’s closest rival.

As when a concept bike production, most of the original gizmos have gone in the translation. The original “vehicle-vehicle warning system”, “cornering system”, “noise cancelling “voice navigation function” and the concept bike “rear monitoring system” – all features of the show bike – are unsurprisingly on the production machine. After the concept version needed to be plugged into the mains via an cord simply to demonstrate its on the show stand, and with power being used to the majority of the bike’s performance, of us would rather see those amps going to the rear rather than powering-up gadgets.

What about the rest of the

Rather than relying on a frame, the engine, transmission, and rear shock are all a single, unit. The swingarm is bolted to the engine/transmission unit, with a rear shock underneath, its ends attached to the bottom of the arm and the of the transmission.

The battery pack and the that operates the system is on top of the transmission, and a a result, the entire including the rear wheel, can be bolted to the bike. That the rest of the machine is made up of a foreshortened front frame carrying the steering head, conventional forks and some bodywork. The same hybrid could, unchanged, be swapped several different machines, the separate front section the chassis geometry and the plastics virtually any appearance.

When can I get

Yamaha’s president, Takashi said back in 2005 the firm would have a bike in production by the end of the decade, so if the is true to its word, the new Gen-Ryu bike will be launched the next few months. Just as the concept was first revealed at the Motor Show, the production debut is likely to be at the same – always used to showcase the latest technology. That you can expect an official announcement by with sales starting in the new year.

Why go hybrid?

In the car world, hybrids are catching on after ten years pioneered by Honda and Toyota. most of the major firms have a hybrid on sale or are to debut one soon. But on two wheels, the is slightly less convincing.

a heavy car to lug about, the ability to use a engine allied to battery to give acceptable performance a lot of sense; there’s no worry being left stranded a flat battery, as the petrol keeps it charged, and there’s no to plug in to the mains for hours every run.

But bikes use relatively small engines, low emissions and frugal economy, so why add all the of hybrid power?

The answer not so much because there’s a need for hybrids from an standpoint but from the realisation the layout offers unprecedented – with the electric motor used more as an addition to the performance potential than as a way of economy. In terms of the new Yamaha, it offer performance and practicality of a big bike – say a 600cc-class commuter – but with an engine only a of that size.

Just as the Gen-Ryu concept promised to 1000cc performance from a engine, the new bike will be to match machines of twice capacity. Given the relatively few parts involved in the electric mechanism, it’s in many a simpler way to achieve performance by adding the complexity of extra more valves, more

Secondly, the flexibility shows in the of use. In a world where increasingly expect to be able to and play”, riding a normal is a frighteningly complex proposition – front and rear brakes, gears, hand controls require you to perform multiple simultaneously.

It might all come naturally you’ve been riding for a but with Yamaha, along the rest of the world’s bike has noticed that an ever-decreasing of people are prepared to learn to do all Bikers are getting old, and need to appeal to a new generation.
