Is it practical to add a 125cc 2-speed, to the offerings? As in Rotax DD2. Gives you something extra to think about without having to basically spend the whole lap twitching away on the gears like you do on a 6-speed. Paddle shift and 30hp+ over a 1/3 of the rev range.

To save some hunting
The primary gear (62) comes in 59-65, the drive gear (35) in 32-38
35/62 is equivalent to 12/90 for 1st gear and 14/79 for 2nd gear
