For the rear the 120/70
For the Front the 110/70
Gonna test just the rear first with a BT601 up front......... just cause it is already mounted and WE know it will stick like glue.
Also the Shinko SR007 is a viable option for pimping around on http://www.bikebandit.com/shinko-tir...36780a4a634822 works well on dirt or pavement...... a great combo tire for general minitard activities.......
It just barely has clearance on the CRII 2005 old school forks.
A local friend of our uses them all the time....... he is at mid pack for race pace on pavement and dirt. he uses them on an Xtreme and a RM85
