CJ750 (长江750)

One obstacle after another..well at least it's back on track...
this will be my first bike - Chang Jiang 750 aka CJ750 (长江750)。

Well..according to the local authority. My Singapore Class 2B license just wasn't qualified to convert to the 'D' license which is required to ride this 3-wheeler.
If there's a will, there's always a way! (有志者事竟成)
and after some inquiry through local network and dealer. I will just need to take a bike lesson at the school specifically catered for sidecar.
and apparently foreigner and those from outside Shanghai are not allowed to take lesson here before April'2010. The restriction have just been lifted and I might possible be the first foreigner to take my D license through this route. The younger Chinese are more interested in BMWs than this old bike from the military. and it's obvious when I apply for the course at the school, the attendant are bewildered and her first respond to her colleague beside is "我今天中奖了!” (I struck a lottery today!)

Well..before I could kickstart my engine. I will need to pass my theory lesson ... in Chinese!
and you think the bad English translation theory test paper is bad enough! try Chinese.. in
All my years of MOE Chinese seems like a kindergarten text book.

Back to my study and before I complete my notes for today. Here's the introduction of CJ750.

The CJ750 motorcycle is based on the 1956 Soviet IMZ (Irbitski Mototsikletniy Zavod) M-72 which was derived from the 1938 BMW R71. Nearly all of them have sidecars. They are often erroneously referred to as BMW "replicas" when in fact, they are derivatives of the IMZ M-72.

Production began in the late 1950s or early 1960s. (Different sources cite different dates.) They were originally produced for the Chinese military and are powered by an air-cooled, four-stroke, opposed flat-twin engine displacing 746cc. The rear wheel is shaft-driven.

The most common models are:
The M1 which has a sidevalve (flathead) engine and a 6V electrical system. This model is a clone of the M72 and closely resembles the 1938 BMW R71.

The M1M is also a sidevalve, however it uses a 12V electrical system and is equipped with a reverse gear. It also has an electric starter where the M1 has only a kick-starter. All of these enhancements were designed by the Chinese.

The M1S (or "Super") uses an overhead-valve engine, 12V electrical system, electric starter and reverse gear. The OHV system is of Chinese design.

All three models use the same frame and sheet metal. The M1 and M1M are nearly identical in appearance, but they can be distinguished by observing certain details.

CJ technological history includes racing bikes, experimental engines and futile attempts at modernizing the appearance of a long obsolete machine. In the 1990s, China opened its markets to foreign motorcycle manufacturers which expedited the end of CJ750 mass production. Today, the marque is kept alive by interest from foreign hobbyists.
