Mounting your GPS to the handlebars of your dirt bike is fraught with difficulty. OK to be honest you can quite happily zip tie it place to your crossbar pad but if you've just spenf several hundred pounds on your new toy you might want to consider something more substantial.

There is a choice of Garmin or Magellan own brand brackets or the more substantial Touratech brackets.

Whichever bracket you use you really should have a permanent power supply to the unit rather than using the batteries. A cheap cigarette lighter adapter is available from most car accessory stores and it can be wired in permanently to a 12v supply.

Relying on batteries alone can cause problems. It must be the knobbly tyres that are the problem. You can ride, jump, hit rocks and slide around off tarmac and the batteries will power your GPS just fine. But as soon as you return to the tarmac and you get up to about 40-50mph the natural frequency vibration is reached and will rattle the batteries sufficiently to make the unit cut out as it thinks it's not getting any power. A permanent power supply ensures a working GPS for as long as you are riding.
