Front and rear suspension upgrade
 

OK I know this is getting done to death at the moment.

I am going to upgrade my front springs and oil and my rear shock on my K6 sport.

What is the best option for doing this without spending huge amounts of money and where is a good place to buy everything I need from. I am a big lover of minimal hassle.

Is the hyper pro front and rear spring kit from Hein Gerick any good. Does this involve getting a new rear shock.

Any info greatly appreciated.

Dan I'm in the process of doing the same, going for uprated ohlins springs (0.80 rating) and preload adjusters (the curvy doesn't have these) which have all been purchased. Also going for a Hagon rear shock/spring unit for the rear (to be ordered when next pay packet comes through), as I've been informed that the original unit goes off very quickly.

However I've had great fun on track (4 times) on the original set up, so I'm hoping with this small upgrade tracks and fast road riding will be even more fun. And the road to Hawes. And the road to Helmsley. And the Alps. And the Nurburgring. And all the other roads!

Hagon's have a single damping adjuster - ie no separate adjustment for compression & rebound. save your money & get a zxr/gixxer shock, probably 1/4 of the price & you get separate compression/rebound adjustment

Does the GSXR shock go straight on an SV? Is it an easy job to do or not?

Re: Front and rear suspension upgrade
 

gixxer shock fits pointy; zxr fits curvy. need to cut battery box. not hard to do if you can support the bike. use the search, this has been covered a zillion times

With the gixxer shock do you have to cut the undertray if ya got one fitted?

And really, really works! :D

Yep, but damping curves designed for completely different bikes... No matter what you do with the GSXR and 636 shocks, you'll never get a "right" result, it'll be a total compromise. The adjustability you get with these shocks doesn't change that- it's still the wrong curve, just that at some points the damping rates will be the same as the right curve would be.

Not saying i'd buy the Hagon, just pointing out that adjustability isn't the be-all and end-all. Ask a B-model 636 owner :) The shock swaps are great for the money. I'd look for a used Ohlins, WP, Technoflex, Penske, etc instead, myself, in fact I did!

Re: Front and rear suspension upgrade
 

I put a 636 shock in my curvey last year. I can say it's a LOT better than the stock unit, but as Northwind says it's still a compromise. The damping is way better, and it improved the bike, for a cheap mod it's good.

I've now upgraded to a Nitron shock, and can say it's a lot better again than the 636. Damping obviously matches the bike, and it's sprung for my weight.

It all depends on how much modding, chopping, and cash you want to chuck at your bike. Obviously a top brand shock is better than a compromise upgrade from another bike, but if you've not got the cash, then talking about spending c. £400 on a shock isn't what you want to hear.

I'd probably recommend using an upgrade shock (636, gixer etc), whilest saving for something better (as I did), if you are outriding the exitsing suspension.

Hi Mate

I have some hyperpro front springs to fit. I ordered them from Calsport for £97 delivered. The guy I spoke to there was really helpfull and recommended fitting the hyperpro rear spring too. Saaid it takes away that "hinged" feeling! He said you need the right spring compressors to do it, or if I sent in the shock they'd fit it for free I'd just pay postage!:cool:
