2 basic mods
 

Hi all,
hope I've got the right page. I've ben reading all kinds of threads,luggage,hard or soft,tyres,wind turbulence,poping,Sat nav mounts,sub plugs,etc.
It seems like so much information. Looking about I'm thinking king there's 2 mods that are simple to do. O2 controller,what is it for exactly.? DNA stage 1 filter,again,what does it do?
Have booked a 5 day trip to Ireland and maniacally trying to figure out what to set up on my tenere before I ride.
Help?
