Dumb question.....

Post by dakotamouse »

Why does the 150 Stella get 140 mpg when the 150 Buddy gets 80? And why is the top speed for the Buddy 65 and the Stella 55?

Is it because of the transmission? Manual versus automatic?

Just curious. :?

Don't count on a 4T Stella (the one I assume you are talking about) getting anywhere near 140 mpg in normal use... maybe 100 if you are light and lucky and easy on the throttle. Most of the remaining difference would indeed be due to the relative lossiness of a belt-drive CVT (where some of the horsepower gets converted to heat from friction instead of "go") compared to the low losses of direct gear drive. This is most true at a steady speed; in stop and go riding, poor shifting technique can negate the differences in efficiency.

If you are talking about the 4T Stella, the claimed top speed is 60+.

Thanks, just wondering. If I had the cash I'd have a whole fleet of scooters and run my own comparisons! :lol:

A Buddy 125 is rated at 90+ MPG and plenty of people get that of even more. I'm going to reserve any assumptions about actual MPGs on a Stella 4 until some folks give feedback after engine break in.

But, regarding the differences, think of it this way: Lots of cars have 4 cylinder engines, but they may all perform totally differently and differ I fuel economy. (No, it's not a perfect analogy.) Different engines in different scooters behave differently; displacement is just one aspect. The Buddy gets much higher MPGs than other 125/150 scooters and will smoke most of them off the line.

here is the major thing that will contribute to better mpgs with the 4 stroke stella it is a manual transmission
back in the day when there were a lot of manual cars the manuals always got better mpg then the autos
and yes the brand new engine desing will paly a role in the better mpg
then you will have the diffreance in gearing that will contribute to better mpg

I'm with Eric. I want to hear what people get in real life. I think the trans will make a big difference. Its really a simple set up crank to layshaft to tree to wheel. Ok..there are a few more parts but it is pretty much a direct drive, no belts, variators, rollers, sliders, centrifugal clutch etc.

What is the weight difference? Top end may be metal v. plastic.

True, what you get for mileage never matches what the sticker says. I love my Italia but I could I'd have a Stella too!
