Fork Springs-K-tech Linear vs Maxton progs?

Hi All.

I've now received my zx10r shock to upgrade my curvy's rear end, but which fork spring replacement is best for the front?

I'm not looking to swap the front end, just replace springs and oil.

at over 18st i know i need 0.9 springs and possibly 15w oil, but i've heard different views over the Linear versus Progressive springs.

any views/advice always appreciated.

cheers

i went k-tech as their local.

I'd go Ktech (or any linear, a spring's a spring). The damping can be better set up with linear.

Depending on how heavy you are I might suggest .95 springs though.

How do you figure out what rate you need for linear?

I've just fitted Race-Tech linear springs and have found a great improvement over the standard.

If you go onto their website they have a spring calculator. Based on that for street use and 252 lbs they are recommending a .95 spring

any change will give an improvement unless of course you are a 7 stone little jap guy.

Linear or progressive?

well technically Linear are better and if all roads were track smooth that's the option I'd go for, however "real world" there not, so unless you are setting the bike up for a single purpose my choice would be to fit true Progressives (progressive springs come in a couple of flavours, those that have a tightening whined the whole length and those that have two different sections to them), but it's a personal choice, I've not met anyone who's changed from standard to either and not been pleased with the results.

hi, i have been looking into this, as my forks are knocking. I was looking changing the springs while i was at it. If you set it up for your weight (which i understand), what happens when you have a pillion on, the set up will not be correct anymore?

My forks are in getting K-Tech linears. Never fancied progressive springs. I want consistancy and fixed up by somebody with a clue.

Let you know in a week.....




.... how pishy and tired my rear shock is.

Aye, but the duel rate flavour of progressives also give a progressive curve, 2 springs "in series" don't act same as 2 springs in parallel.

I've been told/heard they were just an 80s gimmick. Meh miles better than the standard flumps.
