We have a 2004 SV650, which I like a lot except for its suspension.  Can the fork be modified, or do I need to find a used GSX fork and triple clamps?  Any recommendations for a better shock?

Thanks.

GSXR forks and shock is the easiest and cheapest upgrade.

If you don't want to go that route, there's always Ohlins! Bigsmile

You CAN upgrade the stock forks a little...heavier fork oil and springs...but aside from that, I don't think there's much else you can do.

For the rear shock, throw it in the trash and buy a different one.

There are overloads of information at SVRider.com and SV650.org. You can do everything from a simple fork spring and oil change to $1,000 Traxxion cartridges and Ohlins shocks.

I chose to start with springs, emulators and oil in the forks and a ZX10R shock. It cost me about $500 and some garage time. I got to ride it for the first time today and was happy with the results, although I'm anxious to get it out on the track where I can push it a little.

For the forks you can ge the AK-20 from Traction.  It gives you a cartridge fork using your stock SV forks.  For the rear an Ohlins or Penske shock is good.

I just happened to have a Penske 3-way for the 2nd gen SV for sale. Smile

My wife changed the front spring and oil in her SV 650 and this made a significant improvement. We will be adding a new shock as soon as we can get the bucks together.

This is a great bike with lousy boingers.

I don't know of any other emulators out there. Probably the biggest bang-for-the-buck SV mod available.

Depends on how much work you want to do.  The gsxr setup only costs a little more than modding the stock forks, since once you put on the gsxr setup you can sell the stockers to some unlucky person that wrecked.

Iím not saying the GSXR fork swap is a bad way to go, but itís not exactly a bolt-in/bolt out affair. There are several important issues to address.

An option to the GSXR swap that you might want to consider is swapping in a set of 43mm conventional (right side up) forks from the pre-2005 Yamaha R6.

There are a lot of advantages to going this route. The conventional R6 forks cost a lot less than inverted forks from the GSXR, I've seen good sets of R6 forks on ebay for under $100. You also save a lot of money on the front wheel and brake calipers compared to new GSXR pieces, and you won't have to replace the clip-ons or bars. If your stock parts are clean and straight you'll have no problem doing the whole conversion for zero net cost.

You'll also get a hell of a performance increase. The R6 conventional forks are as good as any OEM inverted forks and the Yamaha monoblock calipers are terrific.

One of the guys over at SVForums was the first to do this that I know of. He also has a spacer kit so the R6 wheel will work with SV triples. He's got a good thread with pics of the finished conversion here.

The R6 option sounds more like something that might fit my full-time job, 2-car garage and modest toolbox. I've heard YZF600R forks mentioned as well. I imagine there are still some geometry issues to address as well as how to connect the speedometer.

Skip going with the R6 front end.  Just get the AK-20 cartridge if you are going to go the front end swap route and you aren't racing the bike.

I've done it.  My race bike is in pieces right now so maybe I'll take some pictures are I put it back together.  The bike is a 03 SV650 and it is getting a '06 GSX-R600 front end.

Yeah, I'm culture's boyfriend......


I bought a set of 04 GSXR600 forks for my bike. It's a first gen, so it's not exactly the same. In fact, it's harder if anything.


making the swap on these bikes is MUCH simplier than putting a Suzuki front end onto a Triumph. At least most suzukis are pretty similar.

On a second gen, it's almost entirely straightforward.

I got a pair of forks, lower triple (with steering stem), and radial calipers for 175 shipped. I'm not using the triple, but i'll most likely use it on another one of my Triumphs if i get around to it.

I also bought a Fox shock for 195 shipped. For a full suspension upgrade i'll be just under 500 bucks, most likely. And about 4 hours labor. But i've done this kind of thing before.

I really wish they would give this bike the suspension it deserves from the factory. But hey- they have to do something to keep cost down, i guess.

That's exactly why I chose three other bikes before this one. There is no way anyone will ever convince me that Suzuki had to go with damper rods to meet their price point. Not with as many generations of GSXR's they've gone thru. I suspect it has more to do with fear of cannibalism of GSX-R 600 sales.

But what I really don't understand is why Suzuki doesn't design the bike to be upgradeable with bolt-in parts from their own catalog rather than the aftermarket. I can't imagine how much money they've given away to places like RaceTech, Traxxion and Dale Walker.

With all respect, I disagree. The R6 swap costs less after you resell the OEM SV pieces, you get a nice increase in brake performance along with the improved suspension, and the R6 forks weigh a lot less than the stock SV pieces. Admittedly, the suspension control probably isn't as good as the Axxion AK-20's - but the R6 conversion does cost $1100 less. Heck, you could have the R6 forks overhauled and tuned  to be 95% as good as the AK's and still come out a several hundred dollars ahead.

Different strokes, but that's one of the big things that attract me to the SV. There is so much untapped potential. The first gens in particular have a huge level of aftermarket support, and that makes it possible to get a bike that's really your own and can skin a lot of more expensive bikes.
