I've put about 200 miles on my new Artrax CTX tires already and I love them ! I had ran a set of Big Horns for about 3500 miles but the price of the Artrax caught my eye. The Artrax CTX radials are true to size or maybe a hair taller. They are light and ride like a dream. The only difference that I have found between them and a Big Horn is that I can run the lower on PSI. I ran my BH's at 15 PSI but to get the same tire bulge on these, I have them set at 10 PSI. Motosport.com was a pleasure to deal with also ! Thanks Guys !
