This kind of thing drives the suspension tuners bananas. Especially the ones that focus on valving to control the way the suspension works.THATS WHY I USE HYPERPRO SPRINGS . there not straight rate springs . soft @first then stiffer as you need them
Hyperpro Suspension Upgrade Review
For the street, I think you need progressively wound springs since the weight of the bike varies (solo vs. rider and passenger) and the street is a lot bumpier than any racetrack. Besides, getting the suspension "just right" is answering the wrong question for most street riders. If you really need the suspension THAT GOOD because you ride THAT FAST, get thee to a racetrackery. Post haste.
Disclosure: I actually have Ohlins Road and Track forks and rear shock on my '99VFR800, and it's AWESOME at 220km/h when you're going through a turn and you hit a bump and the bike just shrugs it off. But I don't regularly ride like this, and at normal speeds the Ohlins feels...disappointingly normal.
