  • Page 13: Fi System

    FEATURES EAS39P1102 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator maintains the fuel pressure that is applied to the fuel injector at only 324 kPa (3.24 kgf/cm², 46.1 psi). Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, caus- ing the fuel to be injected into the intake manifold only during the time the passage remain open.

  • Page 17: Outline Of The Abs

    EAS4B56001 OUTLINE OF THE ABS 1. The Yamaha ABS (anti-lock brake system) features an electronic control system, which acts on the front and rear brakes independently. 2. The ABS features a compact and lightweight design to help maintain the basic maneuverability of the vehicle.

  • Page 18
    FEATURES The operation of the Yamaha ABS brakes is the same as conventional brakes on other vehicles, with a front brake lever for operating the front brake and a rear brake pedal for operating the rear brake. When wheel lock is detected during emergency braking, hydraulic control is performed by the hydraulic system on the front and rear brakes independently.
  • Page 19
    FEATURES Brake force and vehicle stability When the brake pressure is increased, wheel speed is reduced. Slipping occurs between the tire and the road surface and brake force is generated. The limit of this brake force is determined by the friction force between the tire and the road surface and is closely related to wheel slippage.
  • Page 20
    FEATURES Wheel slip and hydraulic control The ABS ECU calculates the wheel speed of each wheel according to the rotation signal received from the front and rear wheel sensors. In addition, the ABS ECU calculates the vehicle chassis speed and the rate of speed reduction based on the wheel speed values. The difference between the chassis speed and the wheel speed calculated in the slip ratio formula is equal to the wheel slip.
  • Page 21
    FEATURES ABS operation and vehicle control If the ABS starts operating, there is a tendency of the wheel to lock, and the vehicle is approaching the limit of control. To make the rider aware of this condition, the ABS has been designed to gener- ate a reaction-force pulsating action in the front brake lever and rear brake pedal independently.
  • Page 22
    FEATURES Electronic ABS features The Yamaha ABS (anti-lock brake system) has been developed with the most advanced electronic technology. The ABS control is processed with good response under various vehicle travel conditions. The ABS also includes a highly developed self-diagnosis function. The ABS detects any problem condition and allows normal braking even if the ABS is not operating properly.
  • Page 23: Abs Component Functions

    FEATURES EAS4B56009 ABS COMPONENT FUNCTIONS Wheel sensors and wheel sensor rotors Wheel sensors “1” detect the wheel rotation speed and transmit the wheel rotation signal to the ABS ECU. Each wheel sensor contains a Hall IC. The wheel sensors are installed in the sensor housing for each wheel.

  • Page 24
    FEATURES ABS warning light The ABS warning light “1” comes on to warn the rider if a malfunction in the ABS occurs. When the main switch is turned to “ON”, the ABS warning light comes on for 2 seconds, then goes off, so that the rider can check if the ABS warning light is disconnected and check if the ABS is oper- ating properly.
  • Page 25
    FEATURES 2. When the ABS is activated, the inlet solenoid valve “1” closes and the outlet solenoid valve “2” opens using the power supplied from the ABS ECU signals. This reduces the hydraulic pres- sure. 3. When the ABS ECU sends a signal to stop reducing the hydraulic pressure, the outlet solenoid valve “2”…
  • Page 26
    FEATURES ABS ECU The ABS ECU is integrated with the hydraulic unit to achieve a compact and lightweight design. As shown in the block following diagram, the ABS ECU receives wheel sensor signals from the front and rear wheels and also receives signals from other monitor circuits. 17.Front brake outlet solenoid 1.
  • Page 27
    FEATURES ABS control operation The ABS control operation performed in the ABS ECU is divided into the following two parts. • Hydraulic control • Self-diagnosis When a malfunction is detected in the ABS, a fault code is stored in the memory of the ABS ECU for easy problem identification and troubleshooting.
  • Page 28: Abs Operation

    FEATURES EAS4B56010 ABS OPERATION The ABS hydraulic circuit consists of two systems: the front wheel, and rear wheel. The following describes the system for the front wheel only. Normal braking (ABS not activated) When the ABS is not activated, the inlet solenoid valve is open and the outlet solenoid valve is closed because a control signal has not been transmitted from the ABS ECU.

  • Page 29
    FEATURES Emergency braking (ABS activated) 1. Depressurizing phase When the front wheel is about to lock, the outlet solenoid valve is opened by the “depressuriza- tion” signal transmitted from the ABS ECU. When this occurs, the inlet solenoid valve com- presses the spring and closes the brake line from the brake master cylinder.
  • Page 30
    FEATURES 2. Pressurizing phase The outlet solenoid valve is closed by the “pressurization” signal transmitted from the ABS ECU. At this time, the ABS ECU controls the opening of the inlet solenoid valve. As the inlet solenoid valve opens, the brake line from the brake master cylinder opens, allowing the brake fluid to be sent to the brake caliper.
  • Page 31: Abs Self-Diagnosis Function

    FEATURES EAS4B56011 ABS SELF-DIAGNOSIS FUNCTION ABS warning light The ABS warning light “1” comes on when a malfunction is detected by the ABS self-diagnosis. It is located in the meter assembly. Instances when the ABS warning light comes on 1. The ABS warning light comes on when the main switch is turned to “ON”. The ABS warning light comes on for 2 seconds while the ABS is performing a self-diagnosis, then goes off if there are no problems.

  • Page 32
    FEATURES 3. The ABS warning light comes on while riding. If the ABS warning light comes on while riding, a malfunction has been detected in the ABS. The ABS hydraulic control will not be performed. The ABS will have recourse to manual braking if this occurs.

СВЕДЕНИЯ О МЕРАХ БЕЗОПАСНОСТИ

1 Будьте ответственным водителем

Будучи владельцем транспортного средства, вы ответственны за безопасную и правильную эксплуатацию вашего мотоцикла.

Мотоциклы относятся к однопутным транспортным средствам. Их безопасное использование и эксплуатация зависят от правильного использования техники езды, а также практического опыта водителя. Перед тем как сесть на мотоцикл, каждый водитель обязан знать следующие требования. Вы должны:

Получить подробный инструктаж соответствующих органов по всем вопросам эксплуатации мотоцикла.

Соблюдать предупреждения и требования к техническому обслуживанию, содержащиеся в Руководстве.

Пройти квалифицированное обучение по безопасной и правильной технике езды на мотоцикле.

Проводить профессиональное техническое обслуживание в соответствии с указаниями руководства и/или по мере необходимости исходя из состояния мотоцикла.

вреждения оборудования. Регламент предэксплуатационной проверки вы найдете на странице 4-1.

Мотоцикл разработан для перевозки самого водителя и пассажира.

Преимущественная причина аварий с участием автомобиля и мотоцикла заключается в том, что водители автомобиля не видят мотоциклы при движении. Множество аварий происходят из-за того, что водитель автомобиля не замечает мотоцикл. Чтобы уменьшить возможность аварии такого рода, постарайтесь сделать себя заметным на дороге.

Поэтому:

Надевайте на себя одежду ярких цветов.

Будьте особенно внимательны при приближении к перекресткам или их пересечении, потому что перекрестки являются наиболее вероятными местами аварий.

Ездите там, где вас могут видеть водители автомобилей. Следует избегать участков обзора, закрытых для водителя.

Много аварий происходит по причине неопытности мотоциклистов. Фактически у многих мотоциклистов, которые попадали в аварию, даже не было удостоверения на право управления мотоциклом.

Поэтому вы должны быть квалифицированным водителем и передавать свой мотоцикл только квалифицированным мотоциклистам.

Реально оценивайте свои навыки и умения. Оставаясь в пределах этих навыков, вы сможете избежать несчастных случаев.

Рекомендуем вам попрактиковаться в езде на мотоцикле в местах, где нет оживленного движения, пока вы полностью не привыкнете к мотоциклу и не изучите все его органы управления.

Много аварий происходит и из-за ошибок водителя мотоцикла. Типичная ошибка, которую допускают мотоциклисты, – большие виражи при поворотах из-за БОЛЬШОЙ СКОРОСТИ или наоборот (недостаточный угол крена для скорости).

Безопасная езда на мотоцикле

Перед каждой поездкой на мотоцикле необходимо провести контрольный осмотр. Тщательный осмотр может помочь предотвратить аварию. Невыполнение осмотра или неправильное обслуживание мотоцикла увеличивает риск аварии или по-

СВЕДЕНИЯ О МЕРАХ БЕЗОПАСНОСТИ

Всегда соблюдайте ограничения скорости и никогда не ездите с большей скоростью, чем это рекомендуется указателями на дорогах или условиями движения.

Всегда подавайте сигнал перед поворотом или сменой полосы. Убедитесь, что другие водители видят вас.

Положение тела водителя и пассажира очень важно для правильного управления мотоциклом.

Во время движения водитель должен держать обе руки на рычаге управления, а ноги должны находиться на опорах для ног, чтобы осуществлять управление мотоциклом.

Пассажир всегда должен держаться обеими руками за водителя, ремень сиденья или поручень, если таковой имеется, а его ноги должны находиться на опорах для ног пассажира. Никогда не перевозите пассажира, если он или она не могут твердо поставить ноги на опоры для ног.

Никогда не садитесь за руль мотоцикла, находясь под воздействием алкоголя или наркотических средств.

Данный мотоцикл сконструирован только для езды по дорогам. Он не предназначен для внедорожной эксплуатации.

Защитное снаряжение

Большинство смертельных исходов при авариях на мотоцикле происходит из-за травм головы.

Единственный и самый важный способ предотвратить или уменьшить травму головы – это надевать защитный шлем.

Всегда надевайте защитный шлем.

Носите защитную маску или защитные очки. Ветер, который дует в ваши незащищенные глаза, будет способствовать ухудшению вашего обзора и помешает увидеть опасность.

Использование куртки, тяжелых ботинок, брюк, перчаток и т.д. поможет избежать или уменьшить ссадины или раны.

Никогда не надевайте свободной одежды, потому что она может попасть на рычаги управления, подножки или диски, что приведет к травме или аварии.

Всегда носите защитную одежду, которая закрывала бы ваши ноги, колени и ступни. Двигатель и выхлопная система во время движения сильно нагреваются, и вы можете получить ожог.

Пассажир также должен соблюдать все вышесказанные меры предосторожности.

Остерегайтесь отравления угарным газом 1

Все выхлопные газы содержат смертельно ядовитый угарный газ. Вдыхание угарного газа может вызвать головную боль, головокружение, сонливость, тошноту, потерю сознания и даже смерть.

Угарный газ не имеет цвета, вкуса и запаха, поэтому вы можете не замечать его присутствия, даже если не видите или не чувствуете выхлопные газы. Можно очень быстро вдохнуть смертельно опасное количество угарного газа. Вы потеряете сознание и не сможете спастись. Кроме того, в закрытых и плохо вентилируемых помещениях смертельно опасная концентрация угарного газа может сохраняться в течение многих часов и даже дней. Если вы чувствуете какие-либо симптомы отравления угарным газом, немедленно покиньте помещение и выйдите на улицу. Обязательно обратитесь за медицинской помощью.

Не запускайте двигатель в закрытом помещении. Смертельно опасная концентрация угарного газа может накопиться, даже если вы будете проветривать помещение с помощью вентиляторов или откроете окна и двери.

1Не запускайте двигатель в плохо вентилируе-

мых или частично закрытых помещениях, например, в сараях, гаражах или крытых стоянках.

Не запускайте двигатель на улице в том случае, если выхлопные газы могут попасть в помещение через открытые окна или двери.

Нагрузка

Добавление вспомогательного оборудования или багажа на ваш мотоцикл может сильно повлиять на его устойчивость и управляемость, если изменяется распределение нагрузки. Чтобы избежать возможных аварий, будьте предельно осторожны, когда добавляете какие-либо принадлежности или багаж на ваш мотоцикл. А при увеличенной нагрузке на мотоцикл будьте особенно осторожны при езде. Ниже приводятся несколько общих правил, которые следует выполнять, если на мотоцикл увеличивается нагрузка:

Суммарная масса водителя, пассажира, вспомогательного оборудования и багажа не должна превышать максимальный предел нагрузки. Управление пе-

регруженным мотоциклом может стать причиной аварии.

Максимальная нагрузка:

FZ8-S 195 кг

FZ8-SA 190 кг

Когда нагрузка находится в этих пределах, следует иметь в виду следующее:

Масса багажа и дополнительного оборудова-

ния должна по возможности находиться как можно ниже и ближе к мотоциклу. Необходимо убедиться в том, что вес распределен равномерно по обеим сторонам мотоцикла, чтобы уменьшить неустойчивость и нарушение равновесия.

Смещение веса может привести к неожиданному нарушению равновесия. Поэтому перед поездкой убедитесь в том, что багаж и дополнительное оборудование надежно закреплены на мотоцикле. Постоянно проверяйте надежность крепления принадлежностей и багажа.

Отрегулируйте подвеску в соответствии с величиной нагрузки (только для моделей с регулируемой подвеской), а также проверьте состояние покрышек и давление воздуха в них.

1Никогда не нагружайте рукоятки руля, а также вилку передней оси и переднее крыло какими-либо большими или тяжелыми предметами. Большие предметы, а также такой багаж, как спальные мешки, рюкзаки или палатки, могут стать причиной неустойчивого управления или замедленной реакции рулевого управления.

Данный мотоцикл не предназначен для буксирования прицепа или установки коляски.

Оригинальное дополнительное оборудование от Yamaha

Выбор дополнительного оборудования для вашего мотоцикла является важным решением. Оригинальное дополнительное оборудование компании Yamaha, которое можно приобрести только у официальных дилеров Yamaha, было разработано, протестировано и утверждено компанией Yamaha для использования с вашим мотоциклом. В продаже встречаются запасные части и дополнительное оборудование, а также модификации мотоциклов Yamaha от других производителей. Однако компания Yamaha не в состоянии выполнить тестирование всех аксессуаров сторонних производителей. Поэтому компания Yamaha не может ни одобрить, ни рекомендовать использование дополнительного оборудования, которое было приобретено не у компании Yamaha, или модификаций, не рекомендованных компанией отдельно, даже если они были проданы и установлены официальными дилерами Yamaha.
