Along with this there is an exhaust restriction of some sort in place as even getting to that top speed took an age. In fact I couldn’t test the 0 – 50kph time as we normally do because I couldn’t get the bike to 50kph in the road available. The good thing about this is that for any people stuck with the restrictions they should be reasonably easy to disable... if you are feloniously inclined. The other positive is that this lack of power results in a fairly good fuel consumption rate of 87 MPG

Overall the Flash is a good-looking machine with reasonable braking and handling. Day to day usefulness is also ok if you learn to live with the minor foibles of the centre stand etc. If you are interested in a modern, Italian designed machine and aren’t concerned with pace this may be for you. It would be interesting to see how much the performance increases with the removal of the restrictors because as it stands its performance is poor compared to most of it’s competitors. We will try and get hold of a derestricted version to test the numbers.

NB: All Ratings relate to the tested bike... will be reviewed when/if we can aquire a derestricted version.

I have a Flash which has been hacked to work daily for 3000km. The review is on the mark. As restricted, they are dangerously slow.
Restriction includes a ring in the variator - there are videos on U Tube on how to remove them from yamahas. Removing this gets it up to 55-58kmh indicated. Still noticalby slower off the line than other derestricted scooters and my Hysoung SF50 got to 65 with cut black wire from the CDI.
I am told that these 45kmh ones (including mine) have a restricted barrel - an aftermarket barrel is the only answer, or some serious porting. Looking up the exhaust port should show if it is or not - the port top is flat.
It is reasonably economical - about 30km/l. The Petrol tank by your feet so if yous pill some gas while filling to doesn't fill the underseat compartment and doesn't get in the way of the luggage rack or top box.
Finish is ok, although the chrome rusts. The paint seems to have lasted ok.
The luggage rack is solid, which makes mounting a top box awkward.

In summary, it is not to bad for a Chinese made scooter, and at under $2k on the road for a new one, it is the cheapest "brand name" transport you can get, and at least there is a dealer network so there is some semblance of support. If you can pay more, you certainly get more with other brands, but for under $2k, the Keeway is worth a look - as long as it has been properly restricted. Ride it first.

There may be more than one restriction, possibly an electronic restriction... Im not entirely sure but some of these machines need a wire snipped at the CDI to remove the electronic restriction. Some also feature a restrictor in the gearbox... talk to your local distributor.
