Made my own rack. The Pro-Moto Billet rack I've been using was OK,
but I wanted something that tapered near the front, and something
a little longer to allow for a 10L dry bag to be bungeed onto the rear.
This DIY solution was cheap and quite easy.
The Giant Loop Mojavi system is durable, minimalist, and waterproof.
$209 RockyMountainATV
The side pouches hold about 4.5 Litres each, and 1.5 Litres on the top.
Total storage is ~ 10 Litres.
Then, I added a 10 Litre dry bag to the rear with bungee cords.
Worked very well.
Instead of a traditional tank bag, I went with the
Giant Loop Buck N' Roll tank luggage. It's similar to the
Mojavi saddle bag system in that it has 3 separate storage
Like the Mojavi, it's very rugged and waterproof.
Combined, the Giant Loop front and rear luggage bags I purchased worked very well during a grueling 6-day ride which included 900 miles of mountain passes. And when I added a 10L dry bag, I had plenty of storage for a week's worth of crap.
