Actually.. you want lower psi for the curves and higher if your going to be riding for long times on the highways.. either way, even on the high psi for highway riding, you will still probably want the tires about 2 psi below what they recommend in your book. i run 32rear, 33 front when Im at deals gap or the track (aka lots of twisties) I run around 36 front/rear for street riding. Take note that these pressures are on GSXR's.. pressures will probably be different for your bike. It also depends on the tires.. go to your tire's webpage and there should be a page that tells what pressures you should be running for your model bike / tire. Aftermarket tires do not always run the same pressures as what stock does.. Click the following link and select your tire, then on the right hand side, select "Your Fitment", then select your bike and it will tell your what tire pressures you should be running. http://www.us.metzelermoto.com/en_85/tires/template_categorie.jhtml;jsessionid=X05XQTA2QKQBJFYKJOPCFFA?catid=85SPSUP
