All good, made a world of difference to my SV650, so yes I was happy and I would buy the Hyperpro brand again for another bike if required.
Hey there, I am looking at replacing my stock front springs on my K7 Bandit 650S with the hyperpro springs, while also replacing the rear spring with a hyperpro unit. What has been your thoughts on the hyperpros all in all? good purchase? work well?
No air tool required, just undo the 12mm clamp bolt then use a 22mm socket to loosen the cap.
didnt you need a air tool to get the spring open on the top?

love the video. thank you good sir!
Such a good well demonstrated video. Love how you mention the torque settings for the bolts too. Im picking up my SV650s SK8 today and grabbed progressive front springs for £10 used. Not sure of their brand but they are black in colour so maybe not same as yours.
Hi, the paint finish is excellent (you really wouldn’t know the forks were sprayed up in the garden as a DIY job). The paint has held up much better than I expected, it still looks as good as the day I did it! I didn’t even use a primer, I just made sure those oxidised areas were well rubbed down and the surface clean and dry. The various bolt holes etc were masked by rolling up paper tubes and placing in the holes. Finally, once the paint had hardened I applied some good quality car wax.
Hi good video so thanks for doing it. I am going to paint my forks and can i ask how has the wheel paint held up as it looks good on the video. Thanks.
From what I’ve read the progressive spring is not for all out sports bikes due to the limited travel and the fact they generally have very good quality forks anyway. The stock forks on the SV are pretty basic and I think the progressive springs work well. I’m not too heavy for the bike so the soft part soaks up the bumps while the firm part reduces dive on braking – sorted.
Thanks for the video, I’ll be using it very soon. Can I just ask your opinion on linear springs as opposed to progressive? Opinion is, as ever, pretty divided, but I’m just trying to sound out both camps before making my own decision. Cheers!
Hi, All depends on how the bike has been treated (ridden hard and left to rot or well looked after and serviced). My SV is in reasonable condition and had about 20K on the clock when I did this, the seals looked OK. The other cheap fix is to change the front brake pads to HH rating. A tail tidy gets rid of the UGLY ‘snow shovel’ rear mudguard and an aftermarket silencer makes it sounds nice!
I’m looking into buying a used sv650s probably 2004-2006 (due to price). Most of the bikes I’m looking at have around 15k miles on it. Would you recommend just replacing the fork springs, or should I replace the entire fork kit?
Also, since I’m on the subject what else might need to be replaced on a sv650s with 15k miles.
Thanks for the video, btw very clear and informative.
@ROBOTNINJA500 I don’t consider that, I wanted a quick and cheap fix. A GSXR front end is giant leap ahead of this! I
where you not tempted to throw a gsxr front on her? :L
@panda5188 Hi, yes the springs made a significant difference compared with the stock ones. The hyperpro instructions explain how to setup the static sag for the front end but not the rear. I guess you could look that up if required.
ok thanks for the reply also did the springs make a good difference to the handling? and did effect the handling in relationship the the rear suspension i.e did it need special setttig up?
Hi, Thanks for the comment. Sorry I don’t have any personal experience of using emulators, this is just a straight forward, relatively cheap spring upgrade nothing else required! Well worth the effort – still lovin’ my SV.
Hi this is really helpful video thankyou,i will be fitting these spring to my 04 sv shortly. i just have one question, do you know about fork damper valves also called fork emulators and do in need to fit them when i change that springs?
Thanks for making this, will be having a go myself shortly, cheers.
If you mean by just removing the fork cap and somehow sucking out the oil then yes it is possible but not recommended. I have seen videos of people doing this but you will never get all the old oil and crud out. Also the oil levels would probably be uneven.
If you mean removing both forks and wheel together then NO, you would still have the speed encoder attached, besides taking the wheel off is an easy step. Even if you could leave the wheel on everything else would be a real pain.
Can’t you do this without taking apart the front wheel?
Excellent video. I’m going to do mine pretty soon and this video made it look easy.
Yep, seems to be a pretty universal opinion!
Brilliant, will be using this to do mine. It’s a shame the SV came with (what I’d consider) poor suspension and braking capabilities. A few more quid from Suzuki would of seen the bike come out the factory a lot better!
Thanks, it’s always nice to receive sensible feedback, makes the effort of putting the video together worthwhile.
Best video I’ve seen on this yet. You should definitely do more maintenance videos. You’ve got the knack.
Great video just the right amount of information and pace
Nicely done!
Doing sonic springs on my 00′, thanks for the info. very helpful.
Hi, I just rubbed them down with ‘wet and dry’. Areas that were badly oxidised were rubbed down so no oxidation remained (right back to bare aluminium). I did consider a primer but decided to just use the Simoniz paint. Bolt holes were protected from spray with rolled up pieces of paper. After a few days I protected the paint with some car wax polish. The finish I got was amazing, pretty close to the original. The forks still look as good as when I did them. I’ve not seen this paint in red.
When you sprayed the forks what prep did you do and can you only get the silver paint was thinking about spraying mine red
I have no experience of emulators, try searching SV650.org you may find the answer there.
What are emulators what difference would they make and do they work for the 99 sv650s
Since you already had the unit pulled, but not just toss in a shock from an 06/07 ZX-10? It will give you a stiffer spring rate, full-range preload adjustment, rebound and compression damping adjustment as well as a fully serviceable shock.
Go to the sonicsprings website and input your information into the spring calculator. It will tell you what springrate you should go with. Also, braided lines will help with feel and modulation, but it won’t do anything to address front end dive. Quite frankly, the stock SV damping rod forks suck and you’re going to need to install some emulators or just swap out the things entirely if you want to have decent compression damping.
Had the rear shock spring changed today notice a difference just sitting on the bike it’s is stiffer but not rock hard feels good on road and get the feeling you will get the best if it on track so I would say its worth it because I do quite a bit of road riding and a few tracks days it does limit your preload adjustment tho instead of 1-7 it has to put on position 2-4
Let us know how you get on with the rear shock!
Finally got round to doing my forks today I got SAE 20 oil with mine noticed the difference right away I have the hyperpro shock spring to match not got that on yet also have the steel braided brakes lines front and rear noticed a much better different with them
Hi, The oil I used was supplied in the Hyperpro Kit, SAE15. I weigh about 85Kg (13.4 stone) and yes the dipping has improved significantly, its now progressive (soft enough to absorb the bumps but progressively gets stiffer when under load). I just replaced the brake pads with EBC HH friction rated pads but have not yet changed the oil/brake lines, again a great improvement over what I already had.
Thinking about changing the Springs in my Curvy with Ohlins springs, how much do you weigh if you don’t mind me asking & what oil you used. When you first did this how did it go? I’m not prepared to pay some ‘mechainc’ £50 a hour when I can do it myself & learn at the same time. Also have you got braided lines ? if so has your braking & the dipping in the front end been sitffened up? Cheers.
Thanks just wanted 2 double check gonna be doing the forks next week mine are really soft and not good on trackdays already got the HH pads much better even better with steel brake lines
Yes – it is about 2mm on my bike, I guess the important thing is to get it even! I checked the service manual and it states ‘Align the top of the inner tube to the upper surface of the steering stem upper bracket’. Hope that helps. PS After doing the work on my bike I decided to fit some EBC ‘HH’ friction rating brake pads to the front, again a great improvement for not a great deal of money.
Hi just wondering when you say you have to measure the distance between the top yoke and the cap do you measure how much the cap comes out of the yoke
Thanks
Thanks for the comment. As you know the SV front end is soggy and this really does make a big difference for the cost of the kit (and a bit of your time of course). Braking is so much better and the bike seems much more planted especially when the road is bumpy. Go for it!
awesome video thx a lot
