Thinking of reverting back to stock shock ...

Couple of preload spacers then. Progressives don't have a marked rate IIRC

Surely a progressive spring must have a rating? even if it is a indication of initial rate and end rate? Are there not different progressive springs for different people??? ... the same progressive spring isn't used by a 9st and 19st rider?!?!?

I have actually fitted preload adjusters to it ... but that isn't the solution

Get springs with the right rate for your weight and damp them up with heavier oil.That is a cheap mod and would probably be good enough to balance up the quality of the front against the Kwak shock.(Which isnt an Ohlins or WP is it?)

But you already know that so why am I telling you??????

Progressive spring has a formula not a rating, usually spring rate as a function of compression.

I thought a progressive spring was not really 'progressive' ... it just as a part of it that is at say 70kg/cm then another part that is 90kg/cm ... obviously once the 70KG bit become coilbound, the 90KG bit kicks in ...

Or you telling me it is made up of a whole bunch of ratings and every coil is different? ... I can't believe that ..

Blue are you still banging on about forks? Seems to have been years! No reason to replace the fork seals unless they're leaking. New springs make the biggest difference by a mile, and unless you ride with a pillion then just get linear ones. If you can afford the extra for emulators then do so, but the springs are the worst bit. The idea of making the back worse to match the front strikes me as pretty barmy.

Linear springs are ~£80 aren't they? ... that is 30% more than progressive ... I can't see how they are better either ... they just allow emulators to function better ...

Oh and YC ... looks like progressive springs are exactly as I thought .. not progressive across the range at all ... just have 2 rates!! .. so why can't I know the 2 rates?

If you like, I'll buy the shock off you...?

That is correct, I run Hyperpro springs in the front of the 650.
