This part of the Project Radial Front, I'll be showing the process of fitment of the forks and the possible problems that may occur along the way. As mentioned earlier there's actually 2 approaches to the conversion - either the use of the full GSXR1000 front or the use of the forks only while retaining the Hayabusa triple clamps. I'll now list out the pros and cons of either of these approaches.
Full GSXR1000 Front Swap
Pros
Height adjustable through the top triple clamp
Perfect fit of fork through triple clamps
No need to re-adjust fitment of wheel and axle
Cons
Needs to relocated/adjust the mounting of the steering damper to the head stock
Loss of stock Hayabusa looks
Needs stock GSXR1000 clip-ons to mount on the forks
Stock Hayabusa switches and control may not fit nicely on the clip-ons
Obstruction of gauges (minor) due to the narrower distance between the forks
Stock Hayabusa front fender may not fit.
Steering stem top cover different from stock Hayabusa cover.
Forks, Calipers and Axle Swap
Pros
Retains full top triple clamp looks and functionality
Lower cost as lesser parts are required
Cons
Lower triple clamp are of slightly larger holes than the GSXR1000 forks (1mm difference)
Needs the use of brackets to fit back the original Hayabusa front fender
Wheel axle may not fit nicely for 99-01 Hayabusa.
The approach I took was the forks, calipers and axle swap. Mainly for the reason of retaining the stock hayabusa looks and aerodynamics.
Below will a be a simple walk-through of the entire fitment process done at K&T Accessory Pte Ltd, by Clifford.
First is the removal of the front wheel, fender and the front forks. In the foreground is the GSXR1000 front end.
Removing the stock forks and replacing with the GSXR1000 forks
Making the axle fit with the wheel. Collar inserted
Tightening the axle bolt
Installing the brake calipers before bleeding the brakes
Finished product.
This concludes the section of the installation of the front end. The next part will be the ride review of the newly fitted forks.
The front and rear are both set according to my weight for a static sag of 28mm. The review will be based on riding on the street, highspeed riding on the highway and riding on the track.
Stay tuned for more updates.
