Here they are folks,

Lazarus Sommers of GT Thunder has dyno'd a stock TRX450R and a stock YFZ.

Both the quads were stock, dyno'd by the same operator, on the same dyno, in the same condition (bone stock) - using his dyno tires.

Those that are likely to flame - make note that Lazarus is impartial and calls them as he sees them. He is also a YFZ owner (not a TRX owner). He has no reason to make up numbers or skew results.

Myself and others have been saying for a long time now how close these two quads will be stock - now see for yourself. The torque graph is very interesting...

Also note that the TRX did not rev limit where these dynos stop - he said the rev-limit on the TRX is approx 600-700 RPM lower than the YFZ at approx 10,100 RPM or so.

Here ya go. These will also be on his site soon.
