Most of the enduro racers ride MX bikes. They are lighter, less complicated, better suspension and faster.
In saying this, I ride a 17 450 sxf with rec reg. I’ve previousoy ridden a 15 450 exc which I found boring and hated the pds, a 10 CRF450R which I found flamed out easily however was a load of fun. Before that it was a 07 KTM300 exc.
The new 450 sxf is a rocket ship and I love it. The suspension with the AER forks is unbelievable; can be plush for enduro and with some more air, tuned for the MX track,
I find slow speed single a little taxing however that’s more to do with my lazy ass. Stalling isnt an issue with the KTM either.
As eagle pointed out previously, fuel range on std tank is about 115km.
Any qns, don’t hesitate to ask.
