[size=1em]I am really glad that I did all the mods that I did, to be absolutely honest the linear springs made a huge difference to the front.[/size]
[size=1em]I have heard it said, and I have said it myself that the original FZS 600 springs are progressives, in fact the springs that came out of my FZS 2002 model (2003 Registered) were not progressive they were dual rate springs. [/size]
[size=1em]See photo of original dual rate spring and the new Linear side by side. [/size]
[size=1em]Looking at the the dual rate spring you can see the point where the spring rate changes, just over half way up, that is the problem with the original springs if cornering at speed and you hit bumps the spring rate can change dramatically, changing the geometry of the bike and effect the steering.[/size]
[size=1em]Linear springs are as the name implies are single or linear rate, to compress the spring 1 inch it takes X force, to compress the spring 2 inches it take two times X force and so on, makes for a predictable and more controlled ride.[/size]
[size=1em]You can see that the Linear springs are just a tad shorter than the original Dual Rates springs, this difference was made up by the YSS emulator making up the difference, in fact I had to cut 5mm from the top fork spacers to get back to the right length. If I had fitted the same Ohlins springs without the emulators I would have had to get some slightly longer spacers made up (Any engineering works could do that for around 40 quid) [/size]
[size=1em]If I bought another FSZ 600 I would do most of the work again but this time I would try without fitting the emulators, I would put good quality Linears in that match my fully togged up riding weight (And play around with fork oil weight) and then have a chat with Devilsyam with view to purchasing one of his R6 shocks.[/size]
[size=1em]This way I am guessing that you could do the work for about £300 maybe a little less, and the bike would handle a lot better than the standard FZS, but to be honest the Standard FZS is not a camel, but it can be improved. [/size]
[size=1em]Ohlins are a very good spring. the ones I fitted were for a Suzuki SV 650 rated at 8.5 N/mm, which suited my rider weight fully togged in all my riding kit I am a couple of pounds under 14 stones/ 12.75 stones in my birthday suit (Don't go there). [/size]
[size=1em]To be honest I don't really think that a female pillion would make that much difference to the front end, but she would effect the back much more, but some of that can be sorted with the pre-load on the mono-shock. Again to be honest the is no perfect set up for suspension if some times you ride solo and some time with a pillion or a load of luggage. [/size]
[size=1em]When I bought my Nitron R1 shock Nitron wanted to know my togged rider weight, whether I carried a pillion and how often, how much the togged pillion weighed and also my riding style and they built my shock with the right spring for my requirements, so it's a compromise really, the only time it's not a compromise is when it is done for a raceing bike or track day only bike as everything is a done deal and a know weight then.[/size]
[size=1em]I ride sometimes with my 23 year old daughter on the back and to be honest it does make the bike a bit softer on the back end but can't say I have noticed any difference at the front end, but there again my bike is set up on the slightly harder side as I like to go hooning once in a while.[/size]
[size=1em]Again the Nitron R1 is a great shocker but at 450 quid it really is a shocker, my guessing is that Devilsyam R6 shocks are likely to be a lot less and equally as good if not better.[/size]
[size=1em]My upgrade set me back about £600, but as said earlier I think it could be done going a slightly different route for half and not fitting the emulators.[/size]
[size=1em]If you decided to do the emulators they could be done as a project for another time.[/size]
[size=1em]Let us know your thinking on it all and decisions if any. :thumbup [/size]
