Showa vs. S forks?
« on: October 27, 2021, 08:32:29 AM »
Reaching out to the collective mind here for advice and justification on a loaded question:
Is it worth replacing my fully functional S forks with the 92+ Showas, and why?
I keep hearing/reading here and elsewhere that the Showa's are better, but I can't seem to find much hard info as to why.
My S forks feel fine to me with 7.5w Motul, but I don't have much in the way of comparison---I've ridden only this bike since I bought it in '08, with an R65 before it.
I don't ride especially aggressively, but my commute is ~200 mile round trip on 95 from DC to southeastern PA...so anything that smooths out the ride is welcome. I've already added a Wilbers rear shock, which made a world of difference.
Wondering if this is a 'grass is greener on the other side' sort of situation, or if the Showa's (or Showa's + emulators) really are that much better.
Thanks!

I am guessing that pavement joints are driving you crazy.  I had the same problem with my K75RT.

Gold Valve emulators and springs went a long way toward smoothing out those rhythmic shocks on the awful concrete expressway paving here in Communist Party Paradise known as New York. 

They can be found on eBay for a good price.  Make sure you have the right model emulator.  I can't remember which spring rate I got.

Attached is "hard info"; however, the jury is out on whether it qualifies as "much" in your opinion.  :laughing4-giggles: Get out your reading glasses. It's extracted from BMW's K100/K75 2V service manual downloadable from this site.

One thing to note from that is that you also need to replace both the fork trees and fork brace if you want to swap in the Showa forks so it's more than just a fork swap.
Once I had a Collie pup. Dug a hole and covered him up. Now I sit there by the hour. Waiting for a Collie-flower.

It's the motorcycle suspension equivalent of a non-stick fry pan/fork combination.

Thanks all! Perhaps the auction site will provide.
I think the frork may also be related to the frok referenced for the Brembo  :idunno:.

. .  . so it's more than just a fork swap.
Not really. A fork consists of tubes, stanchtions, upper and lower yokes, the steering stem and, sometimes, a brace. Without all those parts as an assembly, we wouldn't be talking forks; we'd be talking tines, skewers or spears:laughing4-giggles:

When you're riding and you come upon a fork in the road do you:
a) take the left fork?
b) take the right fork?
c) go in between them?
d) run over the fork and puncture your tires?

b) take the right fork?
. . .
If you had to choose between taking the left fork or the right fork, you didn't come across a fork in the road, you came across two forks in the road, but you didn't. The road forked and you had to choose either the left road (tine, spear, leg, skewer) or the right road (tine, spear, leg, skewer), turn around or jump the intersection and test your tires, flip a coin or make roadside camp until a lexicographer was sent by AAA to clarify the situation.  :thisplacewhack

Picked up what I'm hoping is a good set of frorks on Ebay for an acceptable number of dollars...
I'll see how I like them, then maybe emulators.
Gryphon... yep, it's the concrete joints. Baltimore is bad, but 684 is just miserable.
