I am using the 'official' maps/gps information from Sam. I heard too many bad things about gpskevins routes. We have a Garmin Montana 690t and an older Garmin Map60cs as back up.
I currently have the Motoz tractionator I/T and love it, might try the H/T or Desert. Pirelli Scorpion Rally Dual Sport Front Motorcycle Tire (Part# 1537300001) up front right now and seem to like it. I understand the Goldentyre Gt216 is a good tire also
http://www.goldentyre.com/en/dt_portfolio/gt-216-front/ just not sure I want to 'try' a new tire for something like the TAT. I might stick with the Pirelli up front. I used the MT-21 front /rear in 2013 when I did TN-AR section of the tat in 2013 but we wore them down pretty quick though :-( too much throttle perhaps??
Getting (hopefully) the MoskoMoto R80 bags, using a Geigerrig Ballistic 1200 for hydration/backpack
http://www.geigerrig.com/, have Perun's tank bolts and rear rack, AdventureSpec skid and case savers, redoing suspension in June (after we head to Hatfield for a weekend of riding!), replacing ALL fluids, new brake pads. Changed out the orange fuel filler filter for one from Guglatech Filtermaster
http://www.guglatech.com/wordpress/en_GB/ seems to allow better fueling (faster and doesn't overflow as bad - which is what pissed me off about the twinair orange one!). Plan on using trufuel cans to carry extra fuel (my friend uses the premix in his mowers/chainsaw etc, so we are just using the cans and filling with pump gas) same capacity as the MSR type bottles etc, but not $32 each! and disposable when we are done.
