We just received word that Yamaha Motor France, who has some of the top off-road racers on the planet (David Fretigne-ISDE, Amaud Demester-5 time Touquet Beach race winner) has opted to run the Power Now wing in their machines for 2004. It seems that their original dyno testing which was done at full throttle whowed virtually no improvement. But when the tested a 1/2 throttle opening they showed a 2.5 horsepower gain! Their track tests showed identical results, with the riders raving about the mid power increase.
Yamaha of France is ecommending to the dealers to present PowerNow to their customer to improve the bottom end of their WRF.
The Power Now is available from DSP Racing
