3. GPz900R - Streetfighter - The Bike

To start the new Blog we have a GPz900R Streetfighter.

So thanks to Damien for the info on his bike, the 17" rear wheel conversion,
and other modifications.
I will add Damien's direct comments about the handling modifications as part
of this write up.

The Basics:

The bike is a 1992 A8 model.
The rear wheel is a ZZR600 2003, 17"x 4.5", running 160/60/ZR17 Dunlop Sportmax tyre.
The front is still the A8 17"x 3" GPz900R wheel, with 120/70/ZR17 tyre.
The A8 front-end has the 41mm forks and no anti-dive.
The A8 also has 300mm full floating front discs, and twin-piston calipers.
In this case, the earlier GPz900R single-piston top-mounted rear brake caliper is used.
Wide Chrome Bars have been installed.
Forks lowered through triples to compensate for the lowered rear, and for better handling.
Rear Wheel Concentrics spun 180 deg, to raise the rear and sharpen the steering.
And CVK34mm Carbs from 1986 GPz900R,  DynoJet Stage 1 with 137.5 mains, and
individual Uni-filter Pod filters fitted. Main Jet Needle is on the 4th groove.

 

 

This is a really neat and well sorted bike.
It is an example of what simple steps you can take to make your bike better - period.
