Title: Upgrading the 620's suspension Post by: ollie on October 19, 2009, 10:04:34 PM I'm starting to find the limitations and drawbacks of the standard suspension on the little 620 a little tiresome, such as fork dive under brakes, very wallowy through bumpy corners, scraping hard parts when no where near the edge of the tyre etc etc...
I was originally planning on upgrading the fork internals, and fitting a stiffer rear spring and leaving the stock shock absorber alone, I could get this done for around $600. But given the trend of the Aussie dollar I've been spending a lot of time browsing US bike sites, I found the basic Ohlins rear shock for around $600 (incl shipping) http://shop.revercorsa.com/catalog/index.php?cPath=2_44_82 (http://shop.revercorsa.com/catalog/index.php?cPath=2_44_82) , which is way cheaper than what you can get it for locally Is it worth going the full monty and upgrading the shock absorber, or just stick with the spring improvements? Has anyone gone down this path with their 620, or any other thoughts?

Knowing very little about these things I did a fair bit of reading on the forum, even a search for 'Suspension' in OzMonsters will dig up a few topics. Although it was after the fact here is a thread I started recently ... from memory it won't answer your questions but might be worth a read.
http://ducatimonsterforum.org/index.php?topic=28645.0 (http://ducatimonsterforum.org/index.php?topic=28645.0) As for your questions, based on my experience: For the forks you have a couple of options: . change oil and springs to suit your weight ... sounds like this is what you had in mind . swap out your forks for something adjustable ... may require other work as a consequence . cartridge kit ... you don't want to know which path I took As for the rear, this is what I was told by my suspension guru: . do the front first . the rear is not worth upgrading . save your bucks and just replace it when you have the funds So I went the full monty on the back ... well the half monty really ... but changed out the whole shock. I don't know much about one model over the other and I didn't take the Ohlins route (hey I'm different ... and Ohlins on a Ducati, its kinda like owning a red one ;)) so can't offer much there. I think Cairns Duc upgrade to an Ohlins rear on his S2R but I think he stepped up one from the basic model ... he may be able to elaborate a bit more. ... and please don't bring up the exchange rate ... Title: Re: Upgrading the 620's suspension Post by: Spider on October 19, 2009, 10:55:44 PM the 's4rs' is an oem spec 321 shock (which I believe is compatible with both DSS and SSS monsters - I was going to get one for the m1000)
the upgrade is a 333 with a remote reservoir for a SSS, the upgrade for a 620 (being a dss) is a 046 with remote preload adjuster I've been told the same about the sux on the back of the s2r - don't bother spending the money! The showas on the s2r1000/s4r/s4rt are a different matter though - they are worthy! [thumbsup] Title: Re: Upgrading the 620's suspension Post by: Two dogs on October 19, 2009, 11:26:44 PM Hi Ollie ,
suspension upgrade on a Monster (if you are a bigger fella ) is one of the best thing you could do for your ride. This is my solution if it is applicable to the 620 read on [coffee] I went the cheaper option and replaced the front with a set of fully adjustable ST2 forks (new seals + fresh 10 weight oil) from a wrecker just bolt on, and a heavier Ohlins spring on my showa rear shock. Only issue with the front will be the axle on the lower spec fronts don't have a hole to access the compression adjust so the axle need to be drilled to gain adjustment . The rear with a heavier spring is amazing no bottom out no wallowing in corners best $149 you will spend, a "you beut" Ohlins rear with piggy back would of been nice but unless you can get one with a remote piggy back reservoir you will be spending not only buckets of $ on the shock but you will have to remove your crankcase breather unit under the seat( if that is the case with 620) as it wont fit and replace it with an after market breather directly connected to the case. Does you model have the wishbone ? I recall there is an add on to the wishbone bolts to get a lift in the back. If not you will want to look at a new adjustable ride height dog bone as well , all these reasons for my 695 led me to just ramping up my spring rate with good results [thumbsup] also with my 14T sprocket I would of had problems with my geometry leading to to much chain drag on the swingarm. hope that helps a little dez |
