Default 1st truly comparable 450R vs YFZ dyno report

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.

Dyno runs

Wait till you pipe both and the YFZ gains 4 more hp then the R. As HMF and DirtWheels stated.

This is the very first believable dyno! I mean, no one can bet a dollar on a DW issue. Looks like I can be even more confident when I buy my new red toy this summer!
