I wonder if he was making fun of me, referencing to my post where I did 60MPH with my ATM50 (which was downhill a bridge, wind in the back).
And btw, mixing 10W30 with 15W40 is not for better performance, but longer engine life.
If you want best performance you probably should go with 0W20 or something.

yeah, I already owned a 257cc scooter, a 150cc scooter, a 50cc scooter, a few mopeds, and motorcycles. I wanted a new experience. This 125cc is about as close as I can have to the 'perfect' setup.
I find the 150cc scooter I have, has a lot of acceleration power, good for 2 people, but uses more gas than I would have wanted.
First I want to change sliders on my ATM50 to 5.5 grams. If that works out, I'll change sliders of my 150cc, to heavier ones. The 150cc is tuned to go to 5k RPM, which brings it very close to it's torque band. I don't need all that power, in fact, most of the time, I only use 25% of the throttle.
So if I increase slider weight, RPMs will go lower, resulting in better MPG.
However, I think that at best would give me 5-10MPG's more (from 66MPG to ~75MPG).
This motorcycle has a very comparable engine, 127cc instead of 150cc, and manual gears, instead of a CVT. Automatically I suspect that MPG's are going to be higher on it than on the 150cc scooter I have.
I believe 100-125cc is the perfect scooter engine size for 1 person, that doesn't need to be on the highway too often (say max a few exits).
Combined with a manual gearing system allows you to choose from the 2 top gears on the highway (3rd for higher RPM, more torque; 4th for lower RPM, better MPG).
With a CVT there's not a lot of 'gear' choosing to do on the highway. With this manual geared bike neither, but once I change the sprocket, perhaps I could ride in 3rd without losing too much top speed.
I'm a little bit skeptical of the rigidity of the structure (or frame). I'll see how it handles 60MPH, however, only after the breakin, which should be 4-6 weeks from now.

You could take a look at a used burgman, more than enough power, and good for the long rides, but usually they go for just over $4k.
I'm 170 LBS, and my 150cc china scoot takes me up a bridge ~45MPH; I suspect it could get you up ~40MPH. A 250 is indeed recommended.
The 260 EFI i had before could take me up the same bridge @60mph. I presume a Roketa 250 (has carburetor) could take you up a bridge @~50MPH. More than enough, as most cars slow down up a bridge. If you need faster, then WOT right before riding uphill the bridge, so you can gain some speed. The 250cc could get you to 70 or 75MPH, then slow down about 10MPH until you're at the top of the bridge.
Factory deals on Italian scoots are no longer. most people getting good deals, got them in the economic depression. Right now, the economy goes well, so prices stay up.

The whole frame is rather thin! It's lighter in weight than my TaoTao ATM50 scooter. It'll arrive in ~2 weeks. The good thing is that it has a chain drive; so rebelgears will be able to create a custom sprocket, should i want to. It's a 4 gear, most likely in 4th gear, you'll be running in the powerband (~7k RPM) to go 60MPH. I want to change the rear sprocket (and if possible front too) so that I will be running in 3rd in the powerband, @60mph, and use the 4th gear as an overdrive gear; that way I estimate it might be possible to get the MPG's in the 80's or perhaps even in the  's. And should I ever want to ride on the highway, I can always do that in 3rd gear; or in 4th gear but lower speed (eg: 50 MPH). Perhaps what I want is not working really well, so I first have to see how the bike responds in normal traffic. only then can I determine how much of a change in tooth I can go. If the rear sprocket is 44T, I know that 32T will bring down RPM's considerably, but also may make starting from a stop much harder. I probably will go ~8tooth down on the rear, or if possible change the front sprocket. If I could get 2T added on the front I'd be a happy man. On the motorcycle forum, people where making fun of me, because I suggested to go lower than the lowest 38T rear sprocket. The original was 41T, I changed it to 38T, which was good, but then went to RebelGears, and they created a 35T for me, which really works wonders! Now I feel like my 750 acts like a 1200cc on the highway (the RPM's are low). And should I ever want to go faster, or surpass someone, no one prevents me from upshifting one or two gears! But first I need to testdrive the bike, to see how it performs, before I can start calculating. It surprises me there's so little info on this engine type. I'm going to write the company, see if they can send me some info on this engine. |

Have you checked Roketa? They need some wrenching, but many people that know how to do their own work love them! Also the price! The cheapest Roketa you can get delivered in a crate on your front door for ~$1850 (costs $1599, + $240 ship). It does take 2 to uncrate and mount, but if you're strong, you could uncrate it easily with a teenager's help. On this website you can find 3 scooters and 2 motorcycles (250cc) delivered at your door for under $3k! www.superiorpowersports.com/category_s/55.htmI would not go with the BMS, too much trouble in the long run (like excessive vibration, loosening screws, hard to reach and maintain parts), but at least the engine is reliable on that one. On the same website, you can get 150cc scooters from $950 and up delivered at your door. The 150cc's if you're 200-300LBS, are ok for 45-50MPH rides of about 20 minutes. I'm 170LBS, and take my EVO150 out on the highway (60MPH) for just a few exits. Never ran the thing longer than 5-7 full minutes at WOT. I don't know what engine the vespa has, but generally a 150cc Vespa is about as good as a 250cc chinese bike. A 50cc vespa is about as good as a 150cc chinese bike; (IOW: you'll keep up with her). |

It's equipped with a 50cc. Should be able to do 35-40MPH, when rev-unlimited!

most of the metal is aluminum. Magnets are non effective.
Quite often after 2000miles you barely see any flakes in the oil anymore.
Only when you're outside in the sun, or under a strong light, might you see some glittering.

The specs say it has a 154FMI engine. It's seemingly not your common Honda clone engine, but a more modernized crossbike engine.
It says it needs 5W40 engine oil, rather thin if you ask me.
Anyone care to comment on engine, and why this type of engine needs thinner oil?

I've had greatest success in the beginning to just let it idle; then run around at low speeds, and do a lot of engine braking,and small accelerations.
The trick is not to go all out in the beginning, the piston rings could scrape and damage the cylinder wall, so take it easy. Once you've done your first oilchange ~50miles, you can take it a bit faster.
I would not do WOT until at least 100-200 miles, and even then, only occasionally.
I would open it completely, only after 400 miles.

Most 50cc scoots are sold with PDI done, for under $600. I can even get an EVO150, with PDI done for $900 delivered at my door.

My chinese scooter is relatively faster! For the price I'd serial connect 20 chinese scooters, and have 600HP! where do you get a Chinese scooter with 30hp? Try more like 40 Chinese scooters assuming you can actually milk 15 horses out of each. If you can pick them up for $800 each it will cost you $32,000. nice car I'm not a huge Ford fan but that one is ok. Enjoy it Lol! Calculus error! I calculated 30BHP instead of 3BHP. Yeah, need about 200 50cc scooters for that! |

Just take a permanent marker, and re-draw the speeds on the plastic.

Well, not all vespa's are $6000, some are $3000.
