Red = stock 450RBelow are 3 links to comparison runs made on the dyno comparing the TRX450R to the YFZ450. Both bikes were stock, both bikes had about the same amount of breakin time, both bikes were dynoed under the same conditions including 30MPH air blowing across the bike. Interesting thing with the Honda was the ignition was going into a double spark condition at 8400 rpm. The Honda was hitting the rev limiter at 9200 rpm, however on the runs below you will see the graph for the honda stop at 8400 rpm on all the runs that are based on rpm. You can see the full spread on the run that is speed based. In all the graphs - the blue is the YFZ and the red is the TRX.[/b]
