It is too early to say so. Let the test of time speak for itself.
The Suzuki guys are claiming it to be as powerful as a 125cc engine: Suzuki GD110 Specification
This thread also details all the advanced features of its engine.
More and more GDs are graduating from their drive-in periods and are soon going to show us their wild side with throttles broad open. Fingers crossed.
A 2-stroke engine delivers power to the transmission unit earlier than does a 4-stroke engine. It means a 2-stroke engine has an advantage in acceleration department over its 4-stroke counterpart. Put the other way round, given a same engine rating, a 2-stroke engine would reach a specific speed earlier than a 4-stroke engine. But I am not quite sure if just being a 2-stroke engine gives it any edge on the top speed it can reach. Top speed has got to do with transmission, I suppose.
What do you say, mechanical experts?
