I run pavement pressure when on pavement, and off road pressure when off road for extended periods..
My tires are always at 34f/37r unless I'm out playing in wet or soft stuff all day, or out wandering gravel all day.. Then I'll knock em' down to 20ish front and rear, and toss air into them at the first service station after I'm done playing.
The manual's pressure suggestion is a compromise for all riding types, and is actually pretty bad for all types.
When I've run the "recommended pressures" on the road, my bike handles like crap when compared to regular street pressures. It's slow to turn, feels squishy, and low pressure at extended periods increases tire temps, which eat tires.
These are what I do.. I average 15,000-20,000 miles on motorcycles a year, all while having a very busy job and an Upper Midwest riding season.. I've also been doing this now for 30 years.. Everyone can do what they wish, but this is what's worked for me.
