| | | | Detailed first look : 2008 Kawasaki ZZR 1400 | Written: 28/09/2007 : 15:06. Read 22051 times (25/day). | For 2008, changes were made to the ZZR1400’s engine and exhaust system in order to meet strict Euro-III emissions regulations. By reducing mechanical noise, power drops were not only minimised, overall engine character was improved and peak power was increased.

Main specifications
* In addition to the already existing honeycomb catalysers (one in each silencer), a third honeycomb catalyser was added in the collector.
* European models also feature an O2 sensor that measures oxygen density in the exhaust and gives feedback to the ECU. The ECU adjusts the volume of fuel being introduced by the fineatomising injectors, making the fuel-air mixture leaner or richer as necessary, to ensure optimal combustion for clean emissions.
* In order to be able to take into account feedback from the O2 sensor, the ECU is new.
* The cylinder head and cylinder head cover have larger secondary air ports (increased approximately 20%), making it easier to get more air into the exhaust system.
* The Air Switching Valve (ASV) can also handle approximately 5% more air.
Fine-tuned power characteristics
After ensuring Euro-III regulations were met, changes to the engine ensured the best balance for improved power characteristics and meeting noise regulations. The result is an engine with the same great driveablility, a higher peak power, more linear mid-range and stronger low end.
* Intake porting was revised to provide optimum flow characteristics.
* Fine-atomising injectors with droplet size of 75μ increase the lateral spray angle from 15° to 20°, dispersing atomised fuel over a wider area.
* Internal construction of the silencers was revised. Capacity ratio of the first and third chambers was adjusted, as were the lengths of the pipes projecting from the baffle plates.
* Entrances to the connecting pipes (joining header pipes 1-4 and 2-3) were enlarged approximately 75% to compensate for the new collector shape (revised with the addition of the third honeycomb catalyser). This change in particular resulted in enhanced torque characteristics, especially in the low rpm range.
* Emissions and noise levels clear regulations for all markets, allowing almost the same power and torque performance for all markets (except France).
Reduced mechanical noise
By reducing mechanical noise, sacrifices to engine power could be minimised. (Reducing mechanical noise in other areas means less exhaust noise reduction is necessary – and consequently the exhaust system can be tuned for greater power.)
* Revised piston profiles contribute to reduced mechanical noise.
* Urethane sheet added to the inside of the magnesium chain cover also helps reduce mechanical noise.
Chassis
* Forming the cast aluminium sections of the main frame to which the rear frame is mounted using a die casting process instead of gravity casting results in slightly lighter parts, contributing to weight savings.
Suspension / Brakes
Inverted 43 mm cartridge fork and New Uni-Trak linkage rear suspension complement the highly rigid frame, offering both great controllability at high speeds and superb road holding ability when sport riding in the hills.
The ZZR1400’s large-diameter petal brake discs, radial-mount front calipers and a radialmount brake master cylinder offer impressive braking performance and superb feel. ABS
The new ZZR1400 will be standard equipped with ABS for the European market.
Instrumentation
* Nestled in the canopy is an instrument cluster with dual analogue speedometer and tachometer.  White faces make them easy to read.
* Multi-function LCD digital display includes a fuel gauge, gear position indicator, dual trip meters, odometer and clock.
* Use of CAN interface between the meter and the ECU reduces the number of cables and allows a greater volume of information (e.g. fuel consumption) to be exchanged.
