No need to mess with the front end,,

Raising the rear, and not doing anything to the front.. is actually a slight improvement in handing...
Gives you a little less chopper/rake,.. and puts a little more of the weight distribution to the light front end... both good...

The difference is small, and hardly noticeable, but if anything, positive...
Mostly, you are getting a more comfortable ride, and better rear end traction on rough surface roads...
...

I did recently add about 1/4" spacer to the front fork springs,... it very subtly firmed the forks. reducing some dive, and making minute squirlys in the road less noticeable...
It was booger to squish the springs back down the tube by myself though... easier if you had two people...

Thanks for the replies.  It appears that Bill67 and Serowbot did opposite things to get a similar improvement, if "smoother" and "firmer"  are synonymous.  Do both of you have stock front ends?  Anyone with any Progressive Suspension progressive springs in the front?

Front is stock Progressive don't show any fork springs for the S40,I have progressive fork spring in my Suzuki 1500 and they are better and smoother ride.

Thanks for the replies and straightening that out also for the bummer info that PS doesn't make springs for us.

Ryca Motors had Progressive springs made for the forks
Check their website/store; I think they are there.

Just talked to Ryca.  He said won't work unless you are lowering the bike.  He did say that unlike the web page which says
"UPGRADES (sold with kit only)
Progressive front fork springs $75
Front fork springs from Progressive Suspension® for a firmer ride."
they do sell the springs separately.
Talked to Progressive Suspension and they make special ones for Ryca but have no stock ones for us.  He said they'd put it in their "maybe to do list".
