Front Suspension

•

 

Traction, response and damping have been improved by optimizing strut damping response.

•

 

Ride comfort and driving stability have been improved by adjusting the spring rates

Rear Suspension

•

 

Improved damping response and linearity have been achieved and traction, response and damping
have been improved by maximizing the diameter of the shock absorber rods.

•

 

Ride comfort and driving stability have been improved by adjusting the spring rates.

New design 17-inch alloy wheels are fitted. (standard for GSR and RS
(6M/T); optional for RS (5M/T))
Note
For the specifications please refer to Section 8 – Main Accessories.

Steering

1. Steering shaft

• Changing the design of the steering shaft tilt bracket has reduced vibration.
• Increasing the amount by which the shaft sub assembly slides into the pipe sub assembly has reduced the amount by which

the steering wheel moves backwards at the time of a collision.

• Column retention and operability have been improved by introducing a cam to the tilt lever mechanism

2. Oil line

Noise has been reduced by improving suspension insulation and by fitting
rubber mountings to the oil reservoir tank and pressure hose assembly.
