I didn't see where or how it is progressive??? Basically is it an aluminum throttle tube with a slick coating on the inside of both ends to make it turn easier.
Not sure if it is needed or not but FYI, I've never worn out a plastic throttle tube on a road bike, even in close to 127,000 miles on my tengai. Now on my dirt bikes I have worn them out because of the mud and sand getting in there.
So what is it, am I a smart*** or a dumb***? Maybe I'm just an ***hole.
