Hello.
Does anybody have any ideas on how to shave some weight of a standard 139qmb scooter?
What could be left off? And what could be drilled ?

Plastics. The 'lower' skirt can be modified if you don't mind losing about any chance of resale. The mud guards on both wheels can be left home, the air cleaner can be replaced with a smaller, lighter assembly, as can the CVT cover. The muffler is also a bit hefty, and could be replaced. The footrest area can also be lightened as all it does is provide a place to put your feet. If you can create a seat support, the bucket and the cover in front of it can be replaced by whatever you want as long as you have a reasonable perch. Upper plastics could then be left in the garage also. Speed costs money. How much do you have? tom

Probably the biggest weight savings for some would be a diet or hiring a jockey that weighs 80 pounds to pilot the scoot. When you have a $500-$1000 brand new scooter, there aren't a whole lot of frills to ditch. Tom makes good suggestions. The muffler is probably one of the bigger differences if you get something nice and light to replace the stock one. 2Ts tend to be lighter.

Hello and thanks for your suggestions.
I have some big fat aluminium wheels (the aluminum "spokes" covers a large part of the inner wheel) Could the rear wheel be drilled just a little?

Sure. Get out the Black & Decker and go to town. Those silly engineers didn't need to go through all those complicated calculations to determine spoke thickness and spacing. Just drill away. not.
I would not recommend drilling even though the engineers likely designed in 100% over capacity. Castings are known to have voids, bubbles, spots where the alloy is 'just not right'. Design margin is to take care of those situations and still provide a safe ride. Remove the margins at your peril. If you do modify the wheels, you should take responsibility for your mod, and be sure to notify any subsequent owner that YOU have modified the wheels, and will insure their safety. Right? Removing plastics and making substitute designs is one thing, but wheels are essential to safe operation. A lot of time went into their design. Please don't compromise the safety designed in. tom

Extra wide tires and rims add nothing to performance but do add weight. Weight doesn't affect top speed much, just acceleration. Inflating the tires(cold) to max on the sidewall will help both, but may increase wear in the middle and may reduce traction in turns. Find out where there's no traffic and all your riding gear on. What kind of scoot is it? Look at pictures of you crouched down on your scoot from the front, side, and optional from the top (on the center stand is fine). You will probably see ways to reduce wind resistance/drag.

Scootie did the "Ultimate Weight Loss Program". Never mind the trailer and bicycle attached...

All of them. No, really I didn't weight before and after but wheelies got easier. I worried about loss of aerodynamics, but it really didn't change much. I can still tuck pretty well.

U doan need no headlight... Brake lights are for sissies... Turn signals will give away your intentions... and any sort of marker light will give away your location. Wear a reflective vest, or get run over. But, I bet it is fun... tom
