Thanks RC for the rules but still looking for the top speed of the 15f in stock class and what max speed I can reach GPS or radar gun.

Hello Rossi,

I have been competing in stock class with success on my 15F.
R&D ride plate, worx intake and sponsons, airfilter, some water routing in order to get less water in the waterboxes and I have about 64 mph. Talked to some frenchmen at yellow about a new ECU but no improvements on stock machine, +3km/h with new cams...but not allowed.
The stock impeller is the best so fare, tried solas 14/20 but changed back.

Thanks sammy for the info I really appreciate that.
