Well I had the same problem with my Yamaha TW200 and high revs at
highway speed. So now it's like another higher gear, yes less power but
more speed.
On the low end I will need a 55T sprocket because I always want a slower
gear than the original for slow moving in tight places off road.

In my opinion the bike needed one lower off road gear and one higher
gear for the highway. Since I use it mostly on the highway now I have
the smaller sprocket. The people who design these things should ask for
feedback for later model upgrades.

I understand that many years ago they had a 2 speed rear axle. This I
would love to have. It went out of fashion I guess because people were
too stupid to use it.

You expect too much out of what is basically a putt-putt dirtbike
intended for loose sand or deep dirt cover or mud.

You're using it for something it wasn't designed for.

Who would they ask? You?

You don't know enough about motorcycles to even discuss them
intelligently, let alone advise motorcycle engineers about what they
need to do to upgrade a motorcycle that does what reasonable people
want it to do.
