[QUOTE="MoO_coW, post: 123299, member: 19185"] Yes but the 125's say they have RC style valves also. And last year they had RC style valves so it doesn't have anything to do with the new servo controlled powervalves. "Honda’s RC-style exhaust valve features an NSR road-racing-inspired rotary-flap exhaust-valve design that provides a smooth transition between low-range and midrange engine speeds. Also, this year’s exhaust-valve flaps feature a 2.5mm hole for enhanced low-end response. The exhaust flange bore shape is now oval, improving midrange and top-end power as well." [/QUOTE]
