Front wheel and brake
The front setup consists of the following parts;
GS500E forks and front wheel
GSX-R1000K2 single 6-pot caliper and disc |
This caliper came off PP's GSX-R1000K2.
It's the
last model with conventionally mounted six-pot calipers (opposed
to radially mounted) with lightweight aluminum pistons.
|
|
The disc also came off PP's GSX-R1000K2
and FHMoto kindly donated a set of new BRAKING pads. |
 |
| Mark of Manic Motorcycles offered to fabricate the spacer
needed to mate the GSX-R1000 disc to the GS500E wheel. |
 |
And even though Mark suffered major
injuries during an horriffic accident he still found the dedication
to sort me out with the spacer in time. |
 |
Backside of the spacer that mounts
to the wheel. |
 |
This is what it looks like fitted
to the wheel |
 |
From the beginning my main goal was
to be able to retain the upper mounting point so that the caliper
stays as close to the fork leg as possible retaining a standard
look, maximum strength and perfect alignment. |
 |
As this picture shows the thickness
of the spacer is spot on with the disc being dead center of the
caliper. |
 |
The GS500E uses a 310mm disc as standard
but with the 320mm GSX-R1000 disk everything falls together perfectly. |
 |
Time to call in help from Tinie from BikePenR and his machinepark.
So next on the agenda was to somehow modify the lower lug on
the fork leg to create space for an adapter.
The lower lug was shortened and then shaped to somewhat resemble
the lower lug.
|
 |
To ensure perfect alignment of the
caliper a flat surface was machined to the lug. |
 |
This is the basic functional shape
of the adapter block. Looking quite substantial in it's rough form. |
 |
But a few hours on the mill removing
excessive material and it looks incredibly sleek and standard! |
 |
Very pleased with the result! |
 |
Next up are a new front axle and wheel spacers.
The standars axle was too short because I'm using Sprintek's
Slingshot yokes.
|
 |
The wheel spacers have the same stepped-design like the rear
wheel spacer.
Time to brush up on my AutoCAD skills again.
|
 |
Give it to Tinie, go on holiday in the UK and this is what you
get when you come back.
The axle has recesses for a 19mm wrench.
|
 |
The other side. The thread of the
axle is kept a bit long in case any adjustment is needed and I don't
know which nut to use yet as the standard one was shagged. |
 |
And this is the result of many hours
of hard labour by many different people. |
 |
But it really paid off as this totally one-off front end turned
out better than I could have imagined.
Thanks to Simon and Rich @ FHMoto, Mark @ Manic Motorcycles, Tinie
@ BikePenR, Steve @ Sprintek and Fred @ Postmamotoren (for the
brake pump) for their tremendous efforts!
Front end sorted!

 |
The chassis is now allmost completed.
Oh hold on...
- fork brace
- outrigger bearing
- footrests
hmmm... back to work then ;-)
