At this point, I am not thinking about any performance mods. I like the way the bike goes right now. My previous bike was a 2009 Kawasaki Nomad. I had it for 143,000 miles and got an average of 35.5 mpg with it. The R3T blows it away as far as power goes, yet gets about the same mpg. For me it is already a winner.
I have made mods to the bike in terms of lighting, horns, headlight/brake light modulators, LED headlight/driving lights, regulator/rectifier, and a power block. My last big mod will be to add a 6 gallon auxiliary fuel tank in order to extend my range. I had this on my Nomad and loved it. It let me fill up once a week, instead of every 3 days and was great for my long distance rides.
