Progressive Springs (update)
I rode yesterday about 100 miles, a few twistys but mainly flat roads with an occasional uneven spot. I installed Progresive springs with Lucas 10w oil about 18 oz each. I am riding a rather light version if a V2K but I am not so light 265lb, running cobra 230 in rear and metz 888me 130/70 r18 fnt, both at std psi. , both on Britt wheels
Here is what I observed,
- The front end is stiffer, noticeably. To me this is good and bad
- good because I have much more confidence in attacking corners with ease, front end is very accurate and with little "sling-dive" if that is a description. I have very little dive when front braking , so I use my front brakes much more now.
- bad because I have lost full plushness on my front end. There is a road near me with several minor speed bumps in a row, I used to drive over these feeling nothing in the front end, now that has changed, i do feel vibration but nothing that cannot be tolerated. That goes for most bumps.
The rear is more adjustable with spring preload and valve dampening adjustments, but the front isn't unless you like doing full front end tear downs to swap out fork oil, naa me neither.
Bottom line: you cannot have both super plush and performance tuned in the front end of our bikes, For me, I appreciate the sacrifice if losing full plushness for gaining accuracy with minimal dive in braking.
Just thought you should know before you decide to make the change.
