Fork gaiter question... ZM? Jeff? Anyone?

[dougie]

I like the 11 rib gaiters that I see on the "S" bikes, but am not sure how they would fit on Monolever forks.
My 1987 bike has 38.6mm diameter forks as opposed to the 36mm on previous bikes.
Those gaiters look beefy enough that I could enlarge the top opening a bit with a small sanding drum in a Dremel (if necessary).

But I need a couple of measurements -
1. With my forks fully extended (centrestand + wheel off the floor) they would need to be 9 inches long.
2. The diameter of the bottom slider where the gaiters fit on is 53mm.

Any one got a moment to measure theirs?

Gidday Doug, on my bike. 9" from bottom of triple tree to top of slider-fully extended. Approx 53mm top of slider where gaiter fits.
11 rib gaiters.

The gaiters will stretch to fit your larger diameter forks.

Have no idea how they look 'cause I don't look at them, but I used GS gaitors. They fit fine at the top and the bottom fits over the original rubber dirt boot at the bottom. '85 R80.
They are probably ugly.

I use these from Motobins on my 1981 R100RS.

Part No.93901 Scroll across the top to forks....then click the drop down list to see options.

I'm in the process finding gaiters for another bike. I've been hearing a lot about Rancho part number 1952.Rancho gaiters (actually shock absorber covers, but work perfectly as gaiters). I think they are available from. Lordco, maybe Napa. Happy hunting!

Thanks for measuring.
Those numbers sound good.
I like the look of the 11 rib style.

Motobins say a spacer (93909) is needed for those.
What's that about?

Dunno, I don't have it.

I know - I was asking SteveD.
I just ordered what you have from Motobins.

The spacer sits around the fork tube at the top, just below the lower yoke. The gaiter fits around the spacer.

The spacer "seals" the otherwise open gaiter at the top, whilst allowing compressed air to vent under braking.

The spacer has a hole in it, where the small vent tube (seen in the yoke) is sited.

I doubt they're a mandatory part, but they serve a purpose nonetheless.
