An Unholy Union II: Wp Extreme 50mm Conventionals on a G/S
First a short stroll down ADVR memory lane....
Three years ago the original "Unholy Union" came about and documented Elmoreman's adaption of Suzuki DR650 forks onto a R80G/S, following an example by Crankshaft who adapted Honda CR250 forks onto his R80G/S.
Elmoreman's G/S with Suzuki DR650 forks:
Crankshaft's G/S with Honda CR250 USD forks:
Elmoreman's thread showed the way and fellow members bgoodsoil and Hardwaregrrl (who now has the WP 50's as of Feb 2012) and Beater to name a few have tasted the yellow kool-aid and followed this path.
For me, the ideal front end needed to be conventional for the aesthetics, have adjustable compression and rebound damping and be European... nothing against the adapters of the alternative non-Euro sources... but defiling and R80G/S is one thing and putting Japanese parts onto it is a whole different and perhaps a bit edgy proposition than I wanted to take.
Early investigations showed that famous BMW tuners HPN use Marzocchi Magnum conventions in the 50mm size that do have adjustable comp and rebound.
I picked up a set of Magnum 50mm's, my local suspension tuner told me these had two significant negatives one was that the comp and rebound worked in such as way it has no effect for the first 1/3 of the stroke, and two the sliders were too soft and tended to destroy themselves, this he said would be a significant issue on a large bike like a G/S.
While I didn't take any pictures, when I stripped the forks to clean and inspect them I found that the oil looked like melted aluminum. Clearly Magnum's weren't the forks for me.
This left one choice.... from 1997 (or 1998) until 2000 KTM used WP Extreme 50mm conventional forks. Some more digging on the internet showed that many riders consider these to be the best conventional forks ever built.
Having this information I again headed to the internet for Inspiration:
Here's my original inspiration who did this before the others below, CrazyIvan HPN conversion with 50mm Marzocchi Magnums:
Another CrazyIvan creation, with WP 50mm's this time...
And the finished product on the move!
Our own roadsacallin' G/S with R-Dubb triple clamps and KTM 250SX WP Extreme forks
Jay.T's GS with R-Dubb triple clamps and 1998 KTM 380 EXC WP Extreme 50mm's
Redboot's G/S stolen from the UKGS'er forum... his uses triples from Boxersupplier and unknown KTM Wp's
Another unknown, but hosted by Matt Beakers of Boxer Toko/ Boxersuppliers so I would guess these are his triples
Stolen from another thread, can't remember who's bike... unknown model KTM WP 50mm's with a larger rotor and caliper adapter from HE in Germany
Another unknown, but hosted by Matt Beakers who runs Boxersupplier and Boxer Toko (assume these are his clamps)
R-Dubb's G/S wearing some R-Dubb/HPNGuy triple clamps, circa 2008 (no idea on the current status)
