After riding a season on the Hyper-Tech carbon fiber wheels I am going back to aluminum wheel. The Carbon fiber wheels have held up great but make my DS650 too narrow. I lost two inches in the back and front. The 10X5’s front will not let the STU Razorback too float like they should and the 10X10’s make the back too narrow. The 10X9 might work but they would still be narrower than the stock 9X9 due to the offset. I due not think they are the best set up for the DS650 for the desert or dunes. . I will only use them for sand drags
