i do that for track riding
for my streetbike its simply a matter of gas mileage and tire life

 

^ o got ya, i focus so much on performance, i forget why my tire pressure is different.

 

Hell mine ( new bike with michellins are 42/42 ???

 

it also should say it on ur swingarm

 

it does but remember that is the maximum recommended by honda for the max load of the vehicle. its just like a race car. how many cars at the drag strip do you see running full pressure. not the NHRA i mean street tuning nights. none (well at least the smart ones anyway). the lower pressure causes the tire to heat up and grip better. purely for performance. on the street for straight line commuting you really dont need to drop the pressures lower than the 36/42 recommended. this will maxmize tire life and gas mileage but it will make the ride bumpy. in the canyons you can afford to drop them a little but you still arent going to need them as hot as you would on the track.
on the track if the tire doesnt burn you when you pull into the paddock, you either didnt ride it hard enough o there is too much air in the tire.

like a lot of things, it comes down to feel and personal preference. if 10F 10R feels perfect to you run it. likewise with 50/50.

 

I"ve always fill my tires to 34/36...works perfectly for me. I think 42 in the rear is way too much.

 

you guys are nuts, i use around 13 maybe a little higher. Of course im only going to be doing wheelies. HAHA
