SV650s 1st Gen

[Stu23]

Im thinking of having a play with my wife's ( steady ) 1st gen sv650s

Im thinking of making it a touch more track friendly and this revolves around suspension mostly

Ive read heaps on gsxr complete front ends grafted on etc etc seems all i need is a new upper bearing and a front end

Also as to what can be done with the std fronts, springs , cartridge emulators etc etc

As for the rear, needs a better shock for sure, not sure on length but a remote would be better as theres isnt a lot of room under the battery box....

anyone done this before or know of someone who has

Stu try SV downuner http://www.svdownunder.com/index.php. Plenty of people have done the upgrade, a mate of mine as the 2003 model and did it.

From memory a few were putting in ZX6r for the rear

Hey

Thanks for the link........having a good read on what can be done :)

!st gen have an aggressive link - therefore try to use the shock which best compliments that, but maybe that means understanding the design merits and short-comings of each OEM shock(!).

A 41mm damper rod or shuttle valve fork design is always a little annoying, but weirdly enough the most common crime people do is to over damp them - yes it is progressive and this is supposed to always be bad, but sometimes it isn't entirely is it? Indeed many gas fork designs by nature are a little progressive, as an aside. Velocity squared damping is still a bit of a PITA to match a tyre to, sure, but it is not altogether impossible to go well on it by any means.

Personally I would avoid too heavy a front fork - as common as it is to go 750Y-K3 - and instead keep to something with thinner tubes, a 41mm USD is still going to cost a fair bit to get perfect though, which is a shame... (but I know which one I would choose, and it ain't Suzuki's)

On my 41mm RWU damper rod fork (in the Honda 400), I have gutted the original parts from the fork and made cartridges for it - compression, rebound and preload adjustable - so essentially a NIX 20mm design, which ironically I was doing in 400 Honda's years prior to Ohlin's bringing it out, but that don't really matter in teh bid scheme of things! (just saying) - this way we got to keep all the OE parts attached and recycle the correctly lengthed tubes too! :)

*make sure u grease some of the undercarriage bolts, as i have seen some shockers! :p

I'm sure this is the wrong things to say here, but why track an SV650? Those things are like the ideal get-around bike. Good balance, easy to ride, simple mechanicals, punchy and maneuverable... They're such optimized road bikes, it seems like you'd get better track results from less work on other 600's, and you'd almost be wasting an ideal roadie.

Buy an old 600sport and track that. The SV is designed for something else entirely. It's like trying to run a corvette into an off-roader. Sure you could do it, but buy a cheap used ute and convert that keeping the vette for the street.

ive ridden a mates SV650 track bike.

it has a zx10r (08) shock in it, and standard forks.

did a 1.49 on it at EC. it was a little beast. but very slow :)

It was an idea that Janice ( my wife ) and I discussed after i bought my latest R6 trackie, she wasnt sure she would be ok on it hence the idea of modding her SV650 which she loves to be slightly more track friendly. But no offence taken, all points considered :)

why drop down? do it in red group :ayyy:

[Stu23]

aye fair point

It is not how fast you ride but what you take away. No matter how good you are there will be someone faster than you, just ask Rossi

[Stu23]

Nah the front end on my sv650 has to be faar better than that on his Ducati !!
