Veemax, what is the free length of your new progressive springs?
Ummmm, er.... don't know , but I ended up with the spacer's cut to 71mm before I was happy with the preload. There are no apples to compare with apples here , if you get my logic.
After having actually USED the bike on about 300km of gravel and technical offroad now, I can say it is a distinctive improved feel to the front end now , so maybe it's not KTM640Adv-like , but competent enough offroad to make me not care , and hey....no leaky USD seals and all that maintenance horseshit .... real BOOTS to keep Africa OUT of the working parts yes !
The Suzook may be a budget oldtimer but by riding it like you stole it , one gets huge satisfaction.
In the combination of rider + bike , I doubt if this venerable DR is the limiting factor for 90% of weekend adventurers out there.
I would not replace in-spec OEM springs with Progressive springs , just ride the thing, it works. I only chose Progressive coils because for whatever reason, my DR's factory units were really very, very moeg !
