Does anyone know?

[BrandonBlackmon]

I have heard so many different answers to this question, but does anyone know the top speed of a stock 400ex? (4 real)

I took my stock 400 down the road with my gps, It went 64 on dirt and 67 on pavement.
20" tires
14t front sprocket.
Stock exhaust
I brand new bone stock 400, he had 15t front sprocket, I beat him easily low end, but on the top end, we were exaclty the same.

Replace that CDI and you'll gain a few mph. I know when I first ran my 416 with stg 2 cam and stock limiter I hit it in 5th oh pavment. It was barley hitting it, but enough to make it cut out
