there is no such thing as a yz 65 there is a kx 65 and a rm 65 and a ktm 65 but no yz 65
Not too fast
63mph
Depends on the bike.
Not as fast as a GSX-R1000
108.5mph
about 90 mph
around 80
A ktm 65sx will go about 43 but with fmf pipes it will go close to 50
Very Slow! KTM's are NOT worth the money AT ALL!!
Extreamly fast, my friend got clocked at 90mph
The KTM sx is fast but the yfz is the best for what I do, what kind of riding do you do?
