i'd say its about 120km/h
im a 200 plus person and my 380 topped out at 98 and that was pushing it hard. That is all stock parts
The KTM 500 has the the same bore as the 525. In EXC configuration (6-speed) with stock gearing it is good for 95 to 100 mph.
Transmission: Motorex Top Speed 15W50
i have just bought myself a 1996 ktm 360 exc, i have already been up to 155km/h on it with supermoto tyres and it still had more go in it.
65 mphIt is the top speed of KTM 85 sx.
With supermotard tyres about 120-135 km/h. It depends on riders weight, wind, tyre pressures and how fresh your piston is.
i have a 2012 with stock gearing it was still pulling hard at 107mph really hard !! though it was feeling a bit unstable on street with unbalanced tires .
90mph
110mph
I roped my ktm 150sx at 97miles
The Top Speed Is Around 80 mph
