hmm well probably zero. you might need more than a gy6 engine to go any speed. some wheels, a frame, and some steering might be in order. a scooter frame weighs ? but my new frame i built only weighs in at about 16 lbs at the moment, minus forks and any accessories.lol it depends a lot on the scooter. and are we talking stock or modded out without a BBK?i weigh about 135-145 and my stock 160cc benelli with modded stock airbox and freeflow exhaust would let me go just over 60 mph.

about 55-58 or so GPS mph, the chino meter might read 60+ or so but subtract about 8 from that for your real U.S mph.Lefty

I'm a big fat mofo at 340# and I'm able to go 55mph at WOT and all I've done so far is up the jet to 115, swap out the cdi and coil for hi-pro ones and change out the air box for a sock type filter.

Mine would only do about 48 on level ground when I first got it. I drilled the exhaust a little and had the jet changed to a 110, and added maybe two mph. Eventually, I drained the carb (and go a little grit out of it) and adjusted the fuel mixture screw and got a little more mph. Best case, I was doing 54-55 mph on level ground. I weigh 170 lbs.The scooter was a ZNEN copy of a Vespa GTS.

A retro style scooter with 10" wheels and geared for 2 people will go about 52 mph while one with 16" wheels may go 60+ mph depending also on the body style and terrain. At speeds over 35 mph wind resistance becomes a greater factor and the retro-style bikes with their wider/flatter fronts will be more greatly impacted by it.

As has been stated.....your top end depends on the scooter itself, if you have a 150cc GY6. But there are at least three versions of this engine commonly found.....a standard GY6 which is the most common. Then there's a liquid-cooled, fuel-injected version found in high-end 150s like the Honda. Then there's the GY6B engine found in many/most 16" wheel scoots. My own 150cc GY6B scoot would go over 60mph when I got it (GPS). I'm a big person, and even with a windshield, trunk, tools, etc......it'll still do 60 without any speed-mods. ;D

^^^^All the 16" wheel scoots are long case engines. This Xingyue comes with rear disk brakes also. The specs list it around 280lbs if I remember correctly. This scoot is also branded as a BMS Pathfinder 150....a Pathfinder 200 (172cc) is also available.

I built this bike out of junk.It's about as light as you can get a 150cc GY6 powered bike and it has a thin profile.I took it on it's first shakedown ride yesterday, about 50 miles and broke 70 before the valves started to float at about 73mph in a tuck.finished tested mooter 006 by Sneakervolio, on Flickr

The speed on a 150cc varies a lot. If you have wind resistance or are going uphill it slows down a lot. You might get 60 with no wind and going downhill. If you are planning on riding out of town I would get at least a 250cc.
