about 90mph :)
around the 65 mph mark for a big wheel kx 85
75 to 85
fast
maybe 60mph
A KX 85 STOCK WILL TOP OUT AT ABOUT 68-70MPH. well mine will top out at 85mph cause its no normal kx 85
my 99 model kx 250 does 85 mph
bout 65mph
about 90mph :)
a crf150r is like a rocket to a kx85 a crf150r will eat a kx 85 for breakfast!!! there both fast but i have trouble with the kx and no trouble with 150!!! So overall a crf150r runs better and is faster!!!
the suzuki RM 80 could beat it so easy
a kx 85 with a pro circuit pipe on it runs in between 70 and 75 it is a pretty fast bike stock two it runs about 68-70 stock but a perfect bike for a teen about 5 ft to 5ft 4
