Title: K75c rear shock
Post by: Soggz on June 04, 2019, 02:01:06 PM
Hi. I think the damper has given up. Can it be rebuilt with a new damper? Thanks.

Most shocks can be rebuilt depending on brand what brand is it? We can get the OEM one rebuilt and upgraded locally.
Regards Martin.

It’s the hydraulic part of the rear shock. The long silver bit that goes into the shorter fatter black bit, inside the curly black or red bit...

YSS = Bin

Ohlins, Wilbers, Yacugar, Mupo

The YSS was recommended to me by Ted Porter < http://www.beemershop.com (http://www.beemershop.com) > as the best value for our bikes.

I like mine.

Just for clarification, why bin the YSS?
I ask because I have an MZ366 YSS, and although it took a while to set up due to lot's of damping adjustment and infinite preload, it may well be the best "bang for the buck" shock I've ever owned.

Progressive 412 is probably the cheapest at around $300, better than stock but pretty basic.  One nice thing is you can order the 3/4" shorter version if you'd like to lower your seat a bit.

The YES one I saw for a k75c was £132.00. I’m gonna get that one, for now, as my one one my bike simply dosnt move!

That one will be ok, won’t it? I’m a bit skint at the moment, but want to ride my new (to me) k bike!

Rebound adjust of 35-40 steps is "infinitely" too much, Preload is not double nut and the locking screws are a fail.
Cornering stability is shallow when tires on edge and compression/rebound damping over the bumps at speed are irregular and unpredictable.
If your shredding through the twistys and dragging pegs on a regular basis this shock will leave you uninspired.
YMMV

Good luck with your damper.

yeah. I’m not Carl Foggerty, but my bike is giving me back ache. Just want one that takes the huge bumps out, that’s all.

Yep, on this side of the pond, most don't ride like Dave Emde ;) The YSS, although not track worthy, is impressive for cost basis. Don't worry about the adjustment nut...I put a dab of paint once set, and it hasn't moved, but then again, I don't ride like Freddie Spencer or Hailwood.

Crap!  I was hoping to grind the cylinder head off of the RS with my new YSS shock.   Seriously, around here the big thrill in the twisties is not falling into a big pothole or lowsiding on a pile of broken pavement debris.

With the incredibly crap pavement here in upstate New York the best I can hope for is not to bend up the rims too bad.

what's a bloody damper?

It is the correct term for what is commonly (incorrectly) referred to as a "shock".

The SPRING absorbs shocks (bumps).

The damper reduces the oscillations of the spring due to the bump.

Different experience here..

I have Fox remote damper on one k75.
Progressive 465 on another k75.
Full Wilbur's setup on k13.
And yss on the k11 in my shop.

Yss had been excellent over last year and couple thousand miles, mainly in the Twisties.  Easy to adjust, handles very well, and no issues with preload or locking screws.  It ain't a Wilburs or a Fox, but it is certainly a solid damper for the money.

Did not see any were from OP about orthopedic moto appliances for semi-invalids, just saw a conversation about shocks and since im not looking for race Equipment thought I might share shocks in the same price range but thanks for the help, I will make a post in the race section... if I can find it.

It amuses me, that over there, what we call a road,here,is a pavement, there. Our pavement, is your sidewalk. You would get banned from riding, or kill someone, if you rode on the pavement!

Over here, a strip of land dedicated to motorized vehicular traffic is called a road or highway. A road's surface can be dirt, gravel, or pavement. Pavement is usually made from bricks, cobblestones, asphalt, concrete or gold.

You suggest I paint my $400 damper to lock the bloody Pre-load

Which brand do you recommend Interlux,Sherwin Williams,Blue Water,Benjamin Moore,Pratt&Lambert...?

Of course they had roads. They had commerce across the whole continent! There's a great book about it called 1491.

No, he did not suggest you use paint to lock anything.  The paint is to mark it's position so you can tell if it moved.  Very common method to check fasteners.

I like interlux... Especially the anti fouling version!
