Updates for the bigger two strokes are limited this year, it seems all the R+D dollars go into the four strokes these days. The 250 is running a 38mm Mikuni carby, 5 speed transmission and 47mm USD Showa forks up front with a Showa fork out back. The 125 has a 38mm Mikuni carby, 46mm Kayaba USD forks and a Kayaba rear shock. Dry weight for the 125 is 197 pounds, gone are the days when four stroke race bikes were so much heavier than their two stroke counterparts. Honda's award winning motocross flagship continues to go from strength to strength. Updates for '07 include changes to the cylinder head and intake valves. The carb diameter on the 450 has been increased to 41mm and there is also a new brake lever linkage and rear subframe. Showa components take care of suspension front and rear.
