rear shock interchangeability

[Privateer]

I tried searching but maybe I didn't do it very well.

Could someone point out an online resource that will help me figure out what shocks from what bikes I can fit on my 04 620?  Bolt up.. I can't do any fab in my garage.

Upgrading the front/rear suspension is my next step.  I have a line on some S2R1000 forks so i have that covered.  I would just like something equal with more adjustability than what I have now.  I know what I can get new from ohlins and penske, but hoping to find a lower cost option that will be "good enough."


Thanks in advance.

'01 S4 and all '02 and later non-S*R shocks will bolt up.
I *think* S2R shocks will bolt up.
696 shock will not work AFAIK.

Other than S4 units, I don't think the above listed ones have any more adjustability than what you've got.

I've got an '02 S4 shock if you're interested...

yeah, adjustability is what i was looking for, my #1 criteria.

thanks for the info, and PM coming.

I have a 749 fully adjustable shock if you want to try to put that on. My friend just bought the same shock and hes gonna attempt to install it on his 695. Should fit fine.

[Capo]

Didn't the 749 come fitted with a Sachs unit?

yes, but its fully adjustable non the less. i found out the showas are a pregnant dog to come by.

I was pricing out ohlins and penske rear shocks.. and thought wow, if I could find a "take off" that would be ideal.. so, wanted to see what I could find off which bikes that would just bolt on without a bunch of hassle.  Even a remote res i could deal with, but beyond that.. blah. 

I have a line on a S2R front end, so going to get that resprung (210-215 pounds without gear), and get a rear hopefully somewhere. 

I'm really happy with my bike, despite the "small" engine.  I'm really unhappy with the suspension tho.  Never feels planted.  Seams in the freeway concrete beat me to death.  So before anything cosmetic gets paid for, i want to bring it up to snuff mechanically.

The majority of the reason why the bike doesnt feel planted is within the springs. Get stiffer springs and your bike will be MUCH better. valving and shock/fork design fine tunes that experience.

Make sure you are getting S2R 1000 forks over S2R forks. S2R forks are just as shitty as 695/620 forks. If you wanna go cheap and good route just changing out the fork springs will make a huge difference. As for the shocks, trust me on this one, you will not find a penske or ohlins take off for the price youd  think you should get one for. Ive been searching for 2 months now. You can get a penske or matris for about 800 bucks (700 for penske) which is one hell of a deal. If you look around you can get an ohlins for ~$900 range, but most are in the $1,000s. I dont think either shock will be useful due to the fact that you could never push the shock to its full potential. You cant lean a monster or put the monster in situations where the shock was designed to be put into. You'd have damn hell a lot of fun trying though. lol thats my main reason for trying to do a 999 swap. but like a dumbass i bought the sachs version of it over the showa. Both are fully adjustable, and both are better than stock, but showa is better, if you can get your hands on one. you can see my ad in parts for sale.

thanks for the tip.  yeah, i wasn't planning to find an ohlins or penske.  I was hoping to find a factory sachs that someone swapped out for an ohlins or penske.  Looks like Nick has one though.  I had originally planned to just re-spring the stock 620 fork/shock, but then when the S2R forks came into the picture, figured I'd try to upgrade the rear a bit too, as well as respringing.

and yes the front end is off a S2R1000.  one of my buddies is one of those guys who always has like 3 projects going at once and this was something he picked up and isn't using now.  I'll need to get my triples modified to take the forks, apparently, but that'll still be cheaper than any other option.

Triples modified

S2R1000 forks will bolt right on

hmmm maybe I misunderstood what he had.. here's what he told me:

I have a set of Showa 53mm's in my garage. they have a larger upper triple diameter than the Monster. You need to bore out the top triple unless you want to buy a billet upper.

I'll check with him and see what the deal is.  not off an S2R I suppose.

Assuming they're from a Ducati, those would be Superbike forks.

Make sure the caliper bolt spacing is the same as your brakes.
It would require either an aftermarket triple or boring out your existing triple.
Also needs a shim to adapt to the lower triple.
A bit more work, but a good upgrade.

yeah i actually was coming here to post that they were SBK forks.  boring out/shimming the triple wouldn't be too bad, as I know some place that can do it.  but yeah, I didn't think about the caliper spacing et al, thanks for bringing that up.
But would my front wheel fit?  Would the bars still work?  I thought SBK forks were 'taller' which would require clip ons.  Like I said, i want to get this done relatively inexpensively.  If it's too much work, I'll just wait for some S2R forks to pop up, and get some stiffer springs for my stock forms in the mean time.

Overall length of the upper fork legs, from the bottom of the scraper/seal to the top of the cap or adjuster-

SBK forks: 20.5"
Monster adjustable showas: 19.5"
Non-adjustable Marzocchis: 18.5"

The above are 65mm caliper bolt spacing, 25mm axle models.
The axle holes are 30mm on the big end, 25mm on the small end.

Not sure if all SBK forks are 25mm axle or not.

Just did two swaps of adjustable Showas, into M620 and S2R800.
Bar to adjuster clearance was tight.

AFAIK, you would need bar risers or clip-ons for the SBK forks.
