400ex and 450r Horsepower?

[honda_runner]

How much horsepower does the 400ex have ,and how much does the trx 450r have? I just wanna get these facts straight.

[KASCHAK]

the 400ex has 28-29ish stock and i would imagine the 450r has around 45

[RMX500]

it doesn't have 45. check the dyno's at GT Thunder. About 39-40 and the YFZ is about 41-42
