Conclusion

Twenty years of age difference, that means countless model changes, permanent improvements in many small or some larger steps. The result is the incredible level of current super athletes like the ZX-10R. Certainly not the end point of development, but a high point like the GPZ 900 R in its day. What may the future hold? Even more power, even less weight, further technological advances? Ace safe as the amen in church. Even if ?? like anytime ?? hardly imaginable.

Scoring: drive

Dramatic differences:
Past excellence
fade against the potential of modern technology.
It is also remarkable how greedily the ZX-10R drive hangs on the gas. And the entire service? couple, switch, start ?? works better today too. How a gearbox should be stepped was already known earlier.

Scoring: chassis

Just as big the progress with the chassis. The classic runs passably straight ahead, but steers indifferently. The suspension of the ZX-10R
has a certain hardness, the GPZ, on the other hand, is stubborn.

Scoring: Security

With the brakes, the GPZ has to take another, bitter down-
plug in location. Against the
Modern single-finger brakes cannot be used with single-piston calipers. In one point
but the oldie can counter: he feels like hitting the handlebars
practically unfamiliar, solid straight-line stability is its strength. In addition, narrow tires reduce the righting moment when braking in an inclined position.

Scoring: everyday life

Here the differences are no longer so dramatic. Especially since the GPZ, with its larger tank and similarly good fuel consumption, has a longer range than the ZX-10R.

Scoring: comfort

The Achilles heel of modern athletes: limited comfort. Long turns
Both passengers are much more relaxed at the GPZ.

Scoring: costs / environment

18 points more for the environment:
Today’s injection engines
have minimized harmful emissions, although consumption is not so much
was lowered. The price-performance ratio is not directly comparable, a GPZ would be much more expensive today.
