kdx stiffer fork springs

Hey guys just wondering if anyone can tell me what stiffer fork springs I can stick in my kdx (xr springs). That will be cheaper than kdx springs. Ive priced kdx springs at $180 New Zealand dollars ($90 US) this is a bit pricey for me.

My bike is a 1991 KDX200

And I weigh 146Lbs

Thanx Guys

Ive asked for Springs from kawasaki dealer he said they would cost me $180 New Zealand dollars ($90 US) which int cheap is this what you are talking about or are the ones youre talking about cheaper
Thanks

Adding more preload will stiffen the springs i would replace the spacer with a 4.7 inch PVC spacer which will make a noticible difference. This is the cheapest option.
Dont add anymore than 4.7 as you may end up with coil bind.

If you want better fork performance and want to spend a small amout of money then you should try xr400 springs these are cheaper than buying stiffer fork springs specifically for your model And this is probably a better option than adding more preload. If you want more information on this option I can give you address to get to a forum that will give you information about this.

However if you want major increase in front fork performance you may want to consider swapping to a kx front end. This is the most expensive option.

I recommend getting xr400 springs. However if you want a free upgrade with noticable increase in fork performance go with 4.7inch preload spacer this virtually costs you nothing.

I did this mod to my older kdx and i put a 1.3 inch spacer on top of the 110mm that was already in their it worked for me and i only weigh 146Lbs
