      Hi,

      So i am about 6’0 tall and 190lb riding an old margay with a 40mm axle .

      My question is there any advantages of upgrading to a 50mm axle? and what would they be?

      Thanks

      50mm felt more stable when we first tried them during the big changeover. Might be better for your size. Other than that, most new karts are coming with a 50mm setup.

      The only reason you should go to a 50mm is if you can’t get a soft enough axle in 40mm. At the sticky euro tracks they were breaking/bending 40mm axles that were too soft so they went to 50mm. I’m 6’1″ 200 Lbs. and I run a medium 40mm on an old (06) Margay.
