Horsepower??

[Jason Lowery]

Does anyone have a clue about the real horsepower figure of the 450r?? I was looking at the title for my 400ex and it states that it has 34.2 horsepower. Exactly how much stronger is the 450r supposed to be??

[r450rr]

i thought my ex had about 27 or 28

So did I but according to the title the 400's have 34.2.

cool..

but i have no idea about the r,, one of the reviews once said that the r had 42 stock and 48 with the hrc kit... a 13%increase

[tholt]

on the title it is prob. stating horsepower at motor, not rear wheel horsepower. i think rear wheel horsepower was like 26 or 27.

EX had 28 & the 450R is supose to have 42 big increase..

Guys...

The 400EX has around 34HP or so at the crank, but only 27HP at the wheels.

The 450R apparently has 42HP at the crank, and will probably have around 34HP at the wheels.

Do you really lose 20% of your horsepower from the crank to the rear wheel? That seems awfully inefficient.

Thats the way it is though. THats why it is so important have everything properly greased and your chain in good condition. It could cost you 1 or 2 HP if you dont grease right and have the wrong tire inflation. i know all of europe is almost completely converted to calling HP watts and torque in Newton Meter.
