My daughter rides a 2009 F650 and needs new tires. She is a 90/10 rider, going on the dirt for very short intervals. She needs something that will stick on the asphalt and do her justice when we scamper off road for a bit. She is no racer by any means but can tell when her tires don't support her on the road in terms of grip and ' feel' during corner speed. Any suggestions out there?
