Would Aero mods be worthwhile on a 49cc?

[ac7ss]

Playing with the calculator you will notice that the mileage will drop almost by half going from 30 to 40 mph. Aerodynamics matter more (geometrically) with speed. I recently changed my cycle habits to drop down to the speed limit and the first tank gave me an 18% improvement in mpg. (45mpg vs 38mpg) Tests are still underway.

I am considering a mod to add a flexible covering (fabric) from my fairing over my legs to the back of the bike. I feel that this will help lower the total CD. Anybody try this before?

*Note that my scooter has an RPM restrictor, so wide open throttle can sort of effectively end up being more like 2/3-3/4 open throttle.

IMHO, RPM restrictor is a throttle restrictor only when you are at maximal allowed RPM. While accelerating, full throttle is only wasting gas. To save gas don't use full throttle when accelerating.

Ryland/dann_04 - Part of what I'm wondering is whether aeromodding will be worth it, depending on the amount of weight gained from an aeromod, like, if I totally went hardcore and went straight for pure teardrop shape, would the weight gained in materials be justified in terms of the loss of drag? I realize there's probably no easy way to tell, but that's generally the line of thought I'm following.

I weigh about 60-70lbs more than my gf(who knows lol) and on her 50cc 4 stroke she can do 42, i can do 38. You also have to factor in that i am 6 inches taller than her and have about 3 inches more of shoulder so i am like a big parachute compared to her. so i think that just as long as you don't add over 50lbs you should be fine.

Maybe I might try something like a windshield first, or maybe some ghetto cardboard mods. I've heard that the cardboard doesn't necessarily work that well, though.

It's not the material - it's the design that counts.

If you can taper the rear, that's where to start.
