View Full Version : Front Forks Standard Improvments

Okay, so I have fitted Hagon Progressives and new oil which was a massive improvment over stock, however I think I have reached their limits, as I noticed the front end becoming very clunky as my riding is progressing.
I don't want to go the whole GSXR front end thing,partly because I have the comfort kit, and partly because I don't want to stick something old on a new bike.
What are my options with the SV forks, and what is the likely outlay?

Provided teh sag is right and oil level is right, the only other step really are emulators, which are about £100. They take over control of compression damping and add a level of refinement to the whole thing. Still not as good as GSXR but a hell of a lot better than nothing!

what weight oil is in it.
Why did you not go for linea springs?

should have used linear, i found it near imposible to top out the linear spings for my weight and felt fine without emulators

It was the stuff that came with the Hagons - 10W.
I went for progressive because I didn't know any better.

swapping the progressives for linea will allow you to get more from the suspension (as the springs are a constant resistance).
what weight are you without gear?

15.5 Stone without gear.

.85 springs with 15w oil

I would say 0.9 kg/mm or 0.95 with either 10 or 15w oil

-Ralph- changed his 15w oil i think cos it was too much, im sure he thought 12.5 would be better, perhaps he may pop up and give his verdict.

It depends what oil you used as well as 15w in one brand could be 10w in another (viscosity)

This is where it gets a bit of a pi55 take. I am thinking of getting 0.9 springs with 15W oil. What do think?

Dan, ralph is similar weight to you, pm him as im sure he could give his verdict on his set up.

0.9 springs would be fine and 15w would be fine, but i found 10w is fine also :/
The Racetech calculator recommended 0.95 for my 15 stone, and I'm using them with 15W Castrol fork oil and emulators. It has transformed the front end, you can now brake hard without the forks bottoming out almost instantly and it feels far more composed over lumps and bumps.
buy the cheapo emulators from the state, around £35 shipped, currently running those, progressive springs and 10wt oil, the front end is miles better.
Wish i'd known about those emulators before completly swapping the front end of my other bike out and getting the suspension sorted by a pro, as the sv's front end is almost as good as that setup.

OP has a Pointy, so will need some spacers machining to fit the Hardly Movingson emulators.

The brakes are still average and the quality still isn't up to proper cartridge forks. I wish I'd known how easy the GSXR front end conversion was before I started buying springs and emulators.

It's not a cheap conversion though, unless you strike lucky on a cheap GSXR front end and I guess it will load your insurance. The emulators are invisible...

Speak to Yorkie Chris. Depending on how much you are looking to spend he may be able to inject pure voodoo into your forks. Not sure how much else I'm allowed to say!

The cost premise of the GSXR conversion is that you can sell your stock bits off. Yep you'll be meant to declare it on insurance I guess.

Realistically what is the net price of a GSXR front end conversion once you sell off your stock bits?

Depends what age of bits and how lucky you get.
I very nearly broke even on mine, would have made profit if I had not been sold a set of very warped discs

I made a decent profit on my front end swap, although I did touch lucky on a full front end from a breakers for a silly price. All in all, you can do it and easily break even if you can afford to buy bits in winter and sell bits in spring/summer.
The brakes are still average and the quality still isn't up to proper cartridge forks. I wish I'd known how easy the GSXR front end conversion was before I started buying springs and emulators.
I'm happy, they were cheap enough and when i was looking the prices being asked for a gsxr front end were too high, i only paid £850 for the bike so sticking another £300 - £400 of front suspension on didn't really seem cost effective.

I was happy but I test road a few race reps lately and now I'm not so happy!
