Rebuilding Marzocchi Strada Shocks

Nick, as standard there is a plastic cover to stop the spring touching the shock body.
The paint used is a 2 pack acrylic, very tough as he uses a recipe for painting wheels which is very durable.
I get the painted the same colour as the wheels and frame. RAL9006 White Aluminium as per JLO's colour chart.
I should know today if I am off to the UK tomorrow or not, but the plan is to see Clem Thursday evening.
Parts required are seal kit, repaint, stickers, oil, some zinc plating and potentially rod rechroming.
If you are asking me to restore them for you then it would be best to work out what you have and what they need to make them as new again.
We can talk about that off line if you want. The plan is a pub meal and some ales Thursday night.  (cheers) (drunk) (boxing) (pale)

Grant, from pic 2 and3 it seems that the damper assembly differs between both shocks. Is it just looks or is one topout spring shorter than the other? Looks like the bit where the shims are in is different too, other than the colour that is.

Mingh, I checked again this morning and they are identical, except one piston is not yet as clean as the other one.
The springs and the pistons are matching pairs.
 
has anyone bought Strada shock rebuild kits from this seller?

any other sources of rebuild kits? I am looking for two pairs to do two sets of shocks.

Yes, I have, recently.

That website only let's you buy each kit singly (enough for a pair of shocks).

Contact: Dave@windwave.com. for multiple orders. I got a 10% discount for 5 kits which is enough for 5 pairs of shocks. P&P is ?7.50 to a UK address. They have about 100 kits.

Alternatively, contact Gareth at: info@reactivesuspension.com in UK who is a little bit cheaper on kits with P&P of ?6 to a UK address.

Mention the Laverdaforum to negotiate your own discount.

Cheers

DoC!

 
just a stupid question. Both pairs of Marzocchi shocks I have here have the number "4" on the round sticker on the shock body, and those are the same as the photos of the stickers I have just ordered from Grant.

However, I just saw a Ducati bevel earlier today, with what looked to me to be similar if not identical Marzocchi shocks, but there decal marked them a number 2.

what does the number 4 or number 2, or whatever, signify in relation to a Marzocchi Strada shock?

You mean this one, Paul?



If so, it's the spring strength.

Hi Craig

yes, in that example, the number "4", I have seen others on bevel Ducati's with the number "2".

so, 4 being larger than 2, the spring strength on our Laverda fitment marked 4  is larger/stronger/heavier than a fitment marked 2?

Stronger, rather than heavier or longer - at least, that's the way I understand it, Paul  :D.  Btw, when I say "I", I'm bragging  :o.  It's actually what I'm told by a KTM chap who seems to like rebuilding the blessed things ...

In any case, it sure ain't the pressure in the chamber.  That should be 2-3 bar, no more (source: Marzocchi overhaul manual).

("Heavy?  Laverdas?  Dunno what ya mean ..."  :-X).

P.s You're right about Ducrappis, btw (or some, at least).  The Marzocchi AG2s (not Stradas, note.  Dunno if that made a difference ...) on my '79 SSD have a sticker with a '2'.

No idea what spring is fitted to the Maz  Symbols shocks on my Pantah but I did some sag dimensions a couple of days back.27mm with the rider on board and 5mm with the the rider not on it and off the stand.If it has 90mm travel thats about right for a good spring weight to suit me,BUT they go ROCK hard at that 27mm.Almost like there coil bound not using the remaining 50 or 60mm of travel.I am having one of the local suspension gurus rebuild them and will get some info on why they are so blood hard.BTW these have a damping adjuster nob on the remote reservoir that I think reduces the volume of the reservoir.Didn't impress said guru much by there quality,but we will see how he goes.
 
thanks for the info, guys!

I have always found the Marzocchi shocks way too stiff for me, going back to when they were new. On my own bikes they were always the first modification, getting tossed. Too bad I tossed most of them straight into the garbage back in the day, although I did keep the low mileage set I took off my RGS Executive at just over 1,000 miles, and the present relatively low mileage project 1200 TS Mirage (10,200 kms - 6,400 miles) came with an original set on them as well, so I am going to tackle rebuilding both sets.

I am going to look into whether "softer" or maybe progressive springs might be available for the old Marzocchi rear shocks, although if anyone already knows the answer to the question I would really appreciate any information.

I'm running with PLeC here. Surely we can work out what is too 'hard' on these dear old Marzo's and fix it? Maybe I'm sad, but I do like to disctinctly 70's look about them and would like to use them, for the 'completness' of the bike. However, every Lav I have ridden with Marzo Stradas had shocks that were completely knackered, so cannot accurately comment. What is it, learned guys? Spring rate, compression damping, rebound damping, internal friction, some or all of the above?
