Πριν από μερικές ημέρες, η Yamaha δημοσίευσε μία teaser εικόνα για το πρωτότυπο που θα παρουσιάσει στην έκθεση του Τόκιο. Η έκθεση του Τόκιο ξεκίνησε και το σκιερό πρωτότυπο που παρουσιάστηκε ονομάζεται Sports Ride concept.
Το concept έχει μήκος 3.9 μέτρα, πλάτος 1.72 μέτρα και ύψος 1.17 μέτρα ενώ, όντας το πρώτο μοντέλο που χρησιμοποιεί το πρωτοποριακό, ανθρακονημάτινο chassis του Gordon Murray, το βάρος του δεν ξεπερνά τα 900 κιλά – χωρίς όμως να γνωρίζουμε πόσο είναι ακριβώς. Πριν προχωρήσουμε στο πρωτότυπο, ας αναφέρουμε ορισμένες πληροφορίες για το πλαίσιο. Αποτελεί εξέλιξη της διαδικασίας παραγωγής iStream αλλά αντικαθιστά τον υαλοβάμβακα με carbon. Ωστόσο, το iStream Carbon, δεν αντικαθιστά το iStream. Εκτός από τα προφανή οφέλη που έχει στο βάρος, την ακαμψία και την ασφάλεια, το iStream Carbon είναι εύκολο και φθηνό στην παραγωγή. Ο Murray ισχυρίζεται ότι έχει εξελίξει σύστημα που χρειάζεται μόλις 100 δευτερόλεπτα για την παραγωγή κάθε πάνελ.
Η Yamaha ανέφερε ότι το concept χρειάστηκε 5 μήνες για να περάσει από το χαρτί σε αυτό που βλέπουμε αλλά δυστυχώς, δεν έδωσε στη δημοσιότητα περαιτέρω πληροφορίες για τα μηχανικά.

THE YAMAHA BOOTH
The theme of the Yamaha Motor booth for the 44th Tokyo Motor Show 2015 is “Resonate. The Yamaha Motor Product Orchestra.” The booth will display a 20-model array of concept and production models, including six world premiere models and one Japan premiere model. At the Yamaha booth this time, visitors will see Yamaha’s “growing world of personal mobility” unified by the unique Yamaha product development ideal of Jin-Ki Kanno in displays that include electrically power assisted bicycles, scooters, motorcycles, Leaning Multi-Wheelers (LMW), a Recreational Off-highway Vehicle (ROV), an automobile and an autonomous motorcycle-riding humanoid robot that brings together Yamaha’s motorcycle and robotics technology. The creative booth design employs the image of a symphony hall in which Yamaha mobility products and musical instruments converge and resonate together like an orchestra. We hope you will enjoy this display of Yamaha’s “growing world of personal mobility” and the way it fills the booth with the unique resonance of the Yamaha brand.
CONCEPT MODELS AT DISPLAY
LMW – MWT-9
This Leaning Multi-Wheel (LMW) concept model proposes a new type of category in the realm of sport riding. Under a development concept of a “Cornering Master,” the MWT-9 mounts a 3-cylinder 850 cm3 engine on a seamless and dynamically styled body. The exceptional cornering performance provided by the twin front wheels and the bank angle maximized by the outward positioned front suspension forks enable a high level of performance that lets the rider go freely through twisty roads with ever-changing road surfaces and dotted with tight curves in succession.
■ Engine type: Liquid-cooled 4-stroke DOHC ■ Cylinder arrangement: In-line 3-cylinder ■ Displacement: 849 cm3 ■ Fuel supply system: Fuel injection
SPORTS RIDE CONCEPT
This design concept mode takes a uniquely Yamaha approach by putting the involved and active feeling of riding a motorcycle, or “Live and Ride,” into a vehicle with quintessential sports car proportions that adults can enjoy in daily use. Like the MOTIV (displayed at the 43rd Tokyo Motor Show 2013), it employs the iStream* process and is designed to express a driver-machine relationship close in feeling to the world of motorcycle riding. We devoted much attention to the high-quality details and were inspired by the artistic style of Elementarism in designing this proposal for a sports car.

*iStream: A process developed by Gordon Murray Design Limited to produce lightweight, high-rigidity vehicle structures rooted in Formula One technology
This is an autonomous motorcycle-riding humanoid robot built around a fusion of Yamaha’s motorcycle and robotics technology. R&D is currently underway with the goal of developing the robot to ride an unmodified motorcycle on a racetrack at more than 200 km/h. The task of controlling the complex motions of a motorcycle at high speeds requires a variety of control systems that must function with a high degree of accuracy. We want to apply the fundamental technology and know-how gained in the process of this challenge to the creation of advanced rider safety and rider-support systems and put them to use in our current businesses, as well as using them to pioneer new lines of business.
The Resonator125 is a concept model that proposes a lifestyle with an authentic sport bike for young people who have not yet discovered the joys of motorcycling. With a lightweight, slim and compact chassis and an instrument panel assembly using an innovative device, this model melds elements of the near future with the nostalgic for a new fusion of motorcycle eras. It also sports wood panels on the fuel tank and seat cowl with authentic wood grain material used in guitars and engravings on the muffler, fuel tank cap and more done with same intricate techniques used for brass wind instruments. The result is a motorcycle that seeks to inspire young people with concepts and qualities that only the Yamaha brand can deliver.

This electrically power-assisted mountain bike mounts an electric motor on a high-performance bicycle and is designed for adults who want to enjoy the freedom of being able to ride on virtually any terrain. It lets you feel the presence of the power unit where it is most appreciated, like in starts, acceleration and hill-climbing, but with a design that minimizes the visual presence of that same power unit. For added assurance in riding longer distances on any type of terrain, the model is fitted with a large-capacity 400 Wh battery and a multi-function instrument panel. This YPJ project is about offering new value and new scenes for bicycle riding, and this mountain bike concept model redefines the positioning and functions of electrically power-assisted bicycles from a vehicle that makes riding easier to one that opens up a new realm of sporty recreational riding.

In addition to providing a powerful assist in starts, acceleration and hill-climbing, the YPJ-R’s main features are a design that minimizes the presence of the electric power unit and a light, agile ride.
GORDON MURRAY DESIGN ANNOUNCE ‘iSTREAM® CARBON’: A REVOLUTION IN AUTOMOTIVE MANUFACTURING
iStream® Carbon is being shown for the first time at the 2015 Tokyo Motor Show and is the chassis technology used for the Yamaha ‘Sports Ride Concept’ sports car project.
The ‘Sports Ride Concept’ is an in house Yamaha concept design based on an iStream® Carbon chassis developed at Gordon Murray Design working with the Yamaha team.
iStream® Carbon is the world’s first affordable high volume carbon fibre chassis structure bringing Formula One materials and technology within reach of the everyday motorist.
iStream® Carbon sets new standards in the Automotive industry for chassis light weighting, rigidity and safety.
iStream® Carbon is derived directly from Gordon Murray Design’s highly successful iStream® Manufacturing System.
iStream® offers manufacturers:
- A lightweight chassis system without the cost increases associated with all current light weighting technologies.
- A large reduction in capital investment.
- A significant reduction in manufacturing energy.
- New levels of product flexibility from a single platform.
- New levels of chassis rigidity and durability and corrosion resistance.
- New levels of safety.
The new system replaces the glass content in iStream® with carbon fibre which offers even more performance for lightweight and rigidity. Gordon Murray Design Limited has been developing iStream® Carbon for the last 2 years with partners Toray Industries, Innovate UK and ELG, and the process is now fully industrialised.
Unlike any other carbon fibre chassis technology, iStream® Carbon is a fully mechanised system with a cycle time of just 100 seconds. iStream® Carbon is true Formula One racing technology utilising two carbon skins sandwiching a honeycomb core, unlike many expensive handmade supercars which employ monolithic (single skin carbon panels).
The low cost investment and piece part cost of iStream® Carbon components will enable it to be used in sub premium market segments.
iStream® and iStream® Carbon can cater with annual production volumes between 1,000 and 350,000 units per year at a cycle time of 100 seconds and can reduce capital investment by up to 80% reducing manufacturing energy by up to 60% whilst offering new levels of rigidity, corrosion resistance, safety, durability and low cost light weighting.
iStream® and iStream® Carbon represent a major step change in automotive manufacturing.
Gordon Murray Design Chairman – Professor Gordon Murray said:
“Light weighting is the final frontier in the automotive industry fight to lower emissions. There have been great strides forward in engine design, electrical control systems, tyre design and transmission technology, but we are now experiencing a plateau in the advance of technology where the law of diminishing returns comes into play. A step change in vehicle weight to enable downsizing of powertrain and components is all we have left in the armoury. Light weighting is important for internal combustion engined cars, but even more important for hybrids and electric vehicles. iStream® and iStream® Carbon is that step change and is the world’s first affordable, high volume bonded composite structure which sets new standards of safety, rigidity and durability. iStream® delivers performance through lightweight. iStream® Carbon does not replace our existing iStream® manufacturing process, it sits alongside our standard system to open up more market segments for us. We are currently working on 7 vehicles using our original iStream® technology”.
