55-65
With stock gearing 50-55 mph
a suzuki rm can achieve speeds up two 70 - 80 miles and hour
A suzuki rm 85 l will go 115-140 kph depending on if it is tuned and the weight of the rider ect
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
With stock gearing would be in the 75 mph range.
85 mph
65 70 mph
They are both great bikes. They are both fast but the Suzuki RM-Z has a little more power. the Honda is great too but i give itt to SUZUKI RM-Z450
it has 30hp and goes 95mp top speed
It has 30 hp and goes around 92 mph 6th gear full throtle
the rm 250 goes 90mph the rm 250 goes 90mph The one you get from the dealer goes about 65 to 70mph - 5speed close ratio transmission with a big rear sprocket....it might have 45hp, but doesn't have the legs to go 90mph.
