Interesting thread....
I've only been riding sports bikes for about 2 years and until recently have always stuck with the standard 36/42 psi. I've been building up my confidence, skills and speed so up until recently tyre pressures (other than standard) have not been an issue really.
I did a track day on my new Fireblade in October last year and dropped my pressures to 32/32 on the advice of my instructor for the day. I must say I liked the way the bike felt after the change. At the end of the day I pumped my tyres back up to 36/42 and my instructor asked my why, "if I liked the 32/32 why change back?". I didn't really have an answer except that Honda must have good reason to recommend the pressures they do.
I changed my tyres to Qualifier II's a couple of weeks ago and I've decided to plump for 34/36 for now. Mainly because many people seem to like that for the roads (looking at internet forums) and its sort of half way between 32/32 and 36/42.
My question for DUNLOP-RTS is....
The point #3 you refer to in another post suggests that lowering pressure increases traction at the expense of stability. What would a loss of stability due to lower pressures feel like and when would it occur (corners, high speed, braking...)? I did some serious cornering and 140 mph on the (not very long) main straight on my track day with 32/32 and don't think I experienced any instability.
I appreciate your need for caution when talking about street pressures, so any subtle hints would be appreciated!
