Best Springs, do I need Emulators?

The racetech springs are very consistant and cope with mileage, I have found other(cheaper) springs shorten after about 8000miles (ie full service time) needing more preload for the same sag.

If you want good allround road/track performance then Hyperpro springs IMHO are best, not too harsh at lower speeds and stiff enough when needed, however they dont work as well with emulators (being progressive).

15wt oil will give about the right amount of rebound with just springs

PDQ (that’s who you work for right?) who I got my 80 racetech's from do Hyperpro springs:-

I used to work for them, the oil comes in the 'kit' I think its 15wt, having been on the course with the Hyperpro designer I know how much research goes in to their kits---so would fit whatever came in the box.

The distributer changed for Hyperpro, but PDQ can still get them, just wont be in stock but should only be a couple of days to get in.
But I think they're a bit dearer now £114 springs to mind, but dont quote me

HI
I fitted progresive fork springs in my K1 SV the cost of the srpindgs £54.00 labour
ZERO and thet make a hell of a differance use 15wt oil and be presise with the oil.
they have a web site but i cannot remember what it is put that down to old age sorry

Cheers guys

£114 is sounding a darn site closer to £200 than £97 ... it'd almost be worth throwing the extra at it to do the job properly!?!

bikenut34 - £54 ... that sounds more like me what make are they?? I can look them up myself.

I fitted Ohlins springs a year ago, no cutting of spacer needed, straight drop in. If you like back roads I would recommend not using 15 WT oil, I had 15 WT in mine and the front end got a bit lively on uneven surfaces, 12.5 WT is a pretty good compromise. Just had a ride on my mates stock SV the other day and the difference between his suspension and mine (Ohlins front spring and gixxer rear shock) was night and day when pushing on a bit. At the end of the day any reputable spring set up will be better than standard.

Hi bluey

Ok cheers for the info guys! Gonna ring around and get some prices

Recently fitted the emulators, .90kg racetech springs and 20wt oil. The price complete with 2 litres of oil, although I only used 1, and delivery was £206.21 delivered. That was from PDQ. Came through in a couple of days. Good service.
