It is nice to see companies such as Malossi developing products for scooters in general , not just the Majesty. It is an interesting article but unfortunately the test machine had an increase in displacement (new cylinder and piston - 40cc's) so it is impossible to tell how much of the performance increase was variator and how much was engine.
There was also a final gear ratio upgrade in there, that was the full setup back then, available in 3 individual stages, none dependant on the other. They now also list uprated valves and a carburetter.
As they say, Speed is only a question of money, How fast do you wan't to SPEND.
