I guess it's who you ask to define what an 'aggressive MX' port is.
My opinion of a MX port is one that makes low end and midrange power with a broad powerband to get out of the turns faster.
An aggressive MX port would have the exhaust port raised a few degrees higher to raise the powerband up a few more rpms.
A drag and MX port are worlds apart. 2 strokes don't have a rev limit. The higher you turn them the more HP they make.
The drawback is the higher you turn them the narrower the powerband gets.
A drag port is gonna make max HP but have less of a torque curve, and a peaky powerband. Lucky for us the motor has a 6 speed tranny.
This is why on the trails around trees and such you don't want a motor that has a light switch power band like a drag port has.
