Notice concerning Yamaha Motor's announcement on serious accidents involving the electric hybrid bicycle "PAS", in accordance with the consumer products safety law

May 31, 2007

Yamaha Motor Co., Ltd. profoundly apologizes for the concern and inconvenience caused by the voluntary recall of the "PAS Electric Hybrid Bicycle with Rear Hub Unit Drive System."
This report outlines the major accidents reported to the Ministry of Economy, Trade and Industry, from among the additional reports received from customers since the voluntary recall was announced on May 15, and describes the action taken by Yamaha Motor.

1. Establishment of PAS Recall Headquarters
On May 15, the day the report was submitted to the Ministry of Economy, Trade and Industry, Yamaha Motor established an internal "PAS Recall Headquarters," under the leadership of Takaaki Kimura, Senior Executive Officer, to facilitate the implementation of the recall. The Headquarters is made up of a "Call Center," which responds to customer inquiries, a "Recall Team," which recovers customers' vehicles and an "Investigation Team," which examines the actual vehicles.

The Call Center, with a maximum of 95 staff, has, as of May 25, responded to a total of 13,371 calls from customers. The Recall Team is approximately 100-strong and is made up of Yamaha staff as well as employees of our associated retail outlets. With the cooperation of retailers handling PAS electric hybrid bicycles nationwide, we are pursuing recall work (replacement of parts, etc.) at seven recall centers around Japan. The Investigation Team, which has a staff of approximately 30, is investigating the information received on serious product accidents to determine whether or not the accidents were due to defect(s) in the product.

2. Serious Product Accidents Involving the Product
After the voluntary recall was announced on May 15 (seven accidents), from May 16 through May 24, Yamaha Motor received, from customers around Japan, further reports of accidents, and, on May 25, the Company reported a total of 18 accidents, which constitute as serious product accidents under the Consumer Product Safety Law to the Ministry of Economy, Trade and Industry.

The Company came to recognize from an internal investigation that the possibilities are high for two of these accidents as being due to a defect in the product. Investigations are currently under way for the remaining 16 accidents.

7) Company's response: Yamaha Motor apologized to the customer and, with the cooperation of the customer, reviewed the details of the accident, and reviewed the existence of defect(s) in the Company's product.

The approach used in investigating whether or not there were any defect(s) in the product was based

on a comprehensive evaluation involving confirmation of information supplied by the customer,

examination of the external appearance of the vehicle and its components, verification of the history

of defect(s) recorded in the controller, reproduction and confirmation of the phenomena involved in

the accident by riding the bicycle, and dismantling and examination of the components involved.

Verification of the reproduction of the defective phenomena in the bicycle involved, verification of the history of defect(s) recorded in the controller and analysis of the component involved, revealed defects (cracks in the soldering), and it was confirmed that there was a high possibility that the accident would have been caused by a defect in the product.
Yamaha Motor is currently advising the customer to have the defective component replaced, in line with the response measures set out according to the voluntary recall that is currently being implemented, and is responding with sincerity to the customer's injuries.

However, the Company confirmed a history of defects recorded in the controller, thus recognizing this case as "an accident that was very likely caused by defect(s) in the product."
Yamaha Motor is currently advising the customer to have the defective component replaced, in line with the response measures set out according to the voluntary recall that is currently being implemented, and is responding with sincerity to the customer's injuries.

Furthermore, concerning the accidents currently under investigation, Yamaha Motor will continue these investigations, and, for new cases involving accidents, investigations will be opened as required, and when accidents are deemed to have a high possibility of being caused by the product, Yamaha Motor will take swift and appropriate action.
Electric hybrid bicycles have become highly popular owing to their convenience, but Yamaha Motor will continue to strive to enhance product quality and to educate users on their proper use, to ensure safety and peace of mind.
