well iv had a search and nothing really answered my questions i have,

im wanting to upgrade the suspension on my sv650 carbed model,
i dont want to spend stupid money on gsxr k8 k9 ect forks and i dont want to go down the emulator rout with my standard forks.

what i have been looking at is forks from the early gsxrs that came in usd form and also the tl range. iv seen a few tl1000 front ends go pretty cheap including wheel and brakes and i like the thought of the nissin 6 pots they have.

BUT, i dont know which steerer tube is going to fite the sv and if the bearings are going to match up to the frame, i dont mind swpping bits and bobs but i dont want to have to get bits milled and chopped about.

soo, has anyone got a thread or any pointers to whcih front end would suit my needs.

What about just getting the forks revalved and set up to your weight and riding style?

JHS Racing seem to be the guys in the know when it comes to SV's so may be worth giving them a tinkle.

USD doesn't necessarily equal better...

Personally I'd go with Racetech emulators and new springs...

but why pay for the emulators and all that money when for 2-300 quid you can have an adjustable rebound compressioon front end and also the uggraded brakes.

ifind the sv forum not very usefull

Facepalm.

Because the front end will be from an old heavy bike. It will need rebuilding anyway, and will not be sprung or damped correctly for a lightweight SV.

Its cheaper and less hassle to fit the emulators and new springs to your existing forks.

The SV lot are a bit, well, wet. As for different forks - there's not a massive amount to be gained from it; the current forks and brakes are pretty well matched up with the amount of power available on an SV.
All you're really paying for with a USD conversion is bling factor, as far as I'm concerned.

The guys at JHS racing really, really know their stuff, and if they reckon that a properly set up cartridge kit is worth the money, then it probably is. The brakes can be improved* with maintenance and TLC.

*I say this because most instances of people complaining about the brakes on an SV are usually down to having properly furred up brake pistons.

I always wonder a bit when people slate the forks on the SV, and I suspect that the desire is not to improve the handling, but just to have USD forks because they look good.

The standard SV suspension package is excellent, the whole chassis works very well. I remember my old one handling very well, and it was stock, possibly with different springs and definitely with new fork oil in the front.

The problem with them has always been the engine. It just starts to wake up, then you hit the redline. It needs an extra 300cc, and the power shoved down into the midrange.

If you really want to fit USD forks, then a certain amount of machining is always to be expected. At the least you can expect to need to press out the old steering stem and press in the SV one, which is a job for an engineer.

The forks are a bit pants. They have damper rods, which aren't up to the latest cartridge forks, and they are oversprung. However, I'd sort the standard ones before swapping them out, or I'd swap them for a cheap RWU front end like a GSXR600 SRAD.

Getting them resprung/valved and set up for your weight will give you Much better handling than chucking a random front end on.

If you just want blinging USD's them buy them, don't expect it to handle better.

Changing your forks to USD will not effect the handling a great deal.. (not that an average person would notice anyhow) The only thing it will do is improve the looks as stated.
Get the current forks set up for your weight and you will see a transformation straight off.
Thumbs Up
