Whoaru99 has two good points. First being check your pressure gauge against that of several others. Personally I just use a cheap stick gauge, but have checked it against those more expensive ones in some of the shops.
Also if you read MOM then some of the info in there is way, way out of line such as the speeds of shifting & others. I look at the 40psi for my rear & have dropped it to 36 while front setting is 36 though I use 32. My Honda 929 & 953 of '00 & 03 have done well since.
I do not make grunt (short runs around town), but ride up in the mtn roads from 5 to 8+ hrs & no problems with my tyres other then normal wear caused by riding hard. Also on the rear it came stock with 190 & first replacement & every since has been 180 while stock on the front.
I have a '97 Yamaha YZF600R & run same size as stock though again drop the tyre pressure a bit-----more or less why I use on the two Honda bikes.
Unfortunately with a sportbike they do wear out at a faster rate then a cruiser or touring bike, but then entirely different makers to numbers/names used in said cases.
Remember all the others on the road are crazy & out to kill you.
