New QingQi 250 Motorcycles! (QM250-2D, QM260-GY-B)
QingQi has recently announced their two new 250's. One in a half-faired street version called the QM25-2D and the other a 250cc version of our favorite 200cc super-mo.
Both bikes use identical engines which look to be enlarged versions of the QingQi Suzuki DR200 derivative.

Fuel injected TU250-Qingqi QM250-2D
I think the (ASD) suffix might indicate a supermoto version but with a rear disc brake. Note that the 2009 model year Super moto QM200GY-B(ASD) has a rear disc brake as the only difference from previous models.
After having a close look at the 250 versions, it looks as if there's a carburettor in there. You can just about see a float chamber. I don't think the Chinese will go to the extremes that Triumph has gone to with their Bonneville. On this they have made an injection system throttle body that imitates perfectly a CV carburettor, to keep things looking "classic".
Quote:
For 2008, the Bonneville is updated with a new fuel injection system to ensure the Bonneville meets forthcoming Euro 3 legislation. The fuel injected engine is cleaner running than the carburettor version, and is easier to fire up from a cold start. The cool retro styling that makes the Bonneville so legendary remains uncompromised, as the fuel injectors are cleverly concealed by throttle bodies designed to look like carburettors.
On the other hand, they WILL have to adopt fuel injection sooner rather than later. New emissions regulations will force them to. Notice that Honda has withdrawn the popular CBF 250 from the market as it was carburetted, but Yamaha have kept their YBF 250 as it's injected. They both competed in the same market, but Honda has withdrawn it.
When they do we will be looking at increased prices and I hope the usual carelessnes with their design, materials and production techniques does not permeate into their injected models, otherwise we'll be in the shit. Injection systems do not suffer inaccuracies and slapdash assembly or materials gladly.
The Indians have already shown a Royal Enfield engine with fuel injection:

By the way, that TU250 looks beatiful to my old-fashioned taste. It'll probably be made in my home town for the European market at least. I live in Gijón, Northern Spain, where Suzuki has the European manufacturing facility in the old PUCH factory. Mind you, the engines arrive here fully assembled, so they're probably made by Qingqi.
Here's an article detailing the history of the Suzuki plant in Gijón:
