Mr Leonard... I hereby challenge you and your moped to a test of... "Efficiency"!
The mission (should you choose to accept it) would be to determine which form of 2 wheeled transportation is the most efficient in terms of fuel economy.
The test would be..... Any 2 stroke 50cc moped against my 1100cc 20 year old ordinary stock motorcycle.
Run them both till they are out of gas.
Then fill them both with an equal amount (1 gallon?) of their ordinary fuel.
Then ride the same path.
And see who runs out of gas first.
My strategy will simply be to follow you.
I believe you will run out of gas first (getting your normal 60 to 70mpg).
Then I will simply ride past you and go another 5 or 10 miles getting 80mpg at those speeds.. (or at least I think I will) : )
That was my point in discussing 'efficiency' of a ped versus motorcycle.
Despite their extremely low weight and low performance... mopeds are not very efficient at all.
I was surprised to learn this myself .
I used to think my PA50 got 110mpg... then I found out (on this forum!) that it measures kilometers not miles... so I am actually only getting 66mpg or so.
Considering how slow they are going... that is not very good.
Going a steady 75mph... my 100hp 550 pound motorcycle will get 50mpg.
At 75 I am pushing a LOT of air.
Slowing down to 30mph means my economy goes way up... from 50mpg... to ????mpg
Don't anybody take this wrong... I am not ragging on mopeds.
I wouldn't post here if I didn't ride them and enjoy them.
And I don't think this challenge will actually happen (Jamie, we live too far apart).
(though maybe Ron or Ree would be dumb enough (like me) to do this)
Or I could just do a solo test at 30 mph and check mileage.
I justed wanted to point out the truth about efficiency.
If you really want efficient 2 wheeled transportation, you would get a 250cc or smaller 4 stroke motorcycle and ride slowly... they will do 100mpg ridden slowly... and still go 75mph with 20hp when needed.
A mileage competition in the 80's had a bike like I described doing 280mpg after basic modifications (and streamlining).
That was ridden very slowly (like 25mph max) and coasted when possible.
Just a few facts for fun.
I am going riding now. : )
