if it has small wheels i'd say you would have to be 5.0 foot - 5.7 foot but if it has big wheels i suggest 5.3 - 6.0 foot
I have a yz 80 2001 small wheel and does about 75 mph
i have a ktm 85sx and a kx 85 small wheel. i am a midgit but i can ride them. i am twelve. this should help. a kx 85 big wheel is an awesome bike. although if he or she is small it will be too big. a ktm big wheel is expensive but is worth it. it is still quiet big. these are some seat heights kx 85 = 840mm ktm 85 sx = 850mm rm 85L = 850mm cr 85 = 860mm yz 85 = 840mm but all these are ajustable my bros 14 and he rides a ktm 85sx big wheel. he is 170cm tall.
yz 85 will smoke it!!
the first yz 85 was built in 1977
about 14hp at the rear wheel, around 19hp with exaust,ports,valvesreed. etc
NO
different cc
believe it or not, the kx 60 is faster a cause of it having a motor too powerful for the small, light frame, so yes, the kx 60 is faster than the yz 85
a yz 85 goes about any where between 60 and 70 m.p.h
so of them will
yes it can i have done it
60+
