Which way round do they go?

From MB site.......

Normal fork springs work at the same rate on and off no matter what the load is.

Old springs go coil bound and weak, Indian springs can go coil bound and weak as you are fitting them!

Mark designed these special three stage progressive spring to suit all Lambrettas be it race or road.

These three stage springs are computer designed to give a soft feel under normal driving, they increase in strength under braking on large bumps and stiffen even more when under full race braking.

These are the ultimate Lambretta fork springs ever designed.

Another tested product designed by Mark Broadhurst.

Fit them with the tightly wound springs at the top.

And for those who are interested, this is another product especially made in England for MB Developments.

You beat me I remember it as "Tight At Top" or TAT

Thank you lads!

can someone explain why it matters ?
surely the whole spring is taking the compression, regardless of which way up it is ??

If the springs are tight at the bottom they will not spring when riding.

Its all to do with preload. You want to have soft suspension initially and then as the soft springs start to preload the tighter coils will then start to preload and start to stiffen the suspension futher under heavier braking or larger bumps. That's how I understand it anyway

I understand the idea behind different spaced coils along a spring's length.
but how does the spring know which part to use first ?

Bilko, put one in the "correct" way and the other one the "wrong" way and report back.

if you are using mbd ones then you may want to use ther double top hat thingies to give a bit of pre load as i found them too soft for my liking.
