YAMAHA ZUMA 50 / BWs 50 (CW50, YW50) First introduced back in 1989 and still on sale as of 2018, the Zuma 50 (aka BWs 50 in Canada) is Yamaha’s widely popular sports scooter. Over that time the Zuma has gone through two model codes (CW50, YW50), three generations, and a huge number of names (Zuma, Zuma II, Zuma 50F, Zuma 50FX, Zuma X, BWs, BWs 50, BeeWee). The sections below discuss each of these generations. Generation One: 1989 - 1990, 1997 - 2001 The first generation of Zuma (above) was the ‘non bug eye’ version (model code CW50). With a sporty look and fat tires, the first generation Zuma made it cool to be a scooter rider. It quickly became very popular due to its aggressive styling and 2-stroke motor with substantial performance potential. Briggs And Stratton 136200 Manual there.
The CW50 was first launched in the USA and Canada for 1989 but this initial offering lasted just two years (1989-1990) before taking a hiatus. Yamaha pulled the CW50 from North America after 1990 because of supply shortages caused by its huge popularity in Europe. Finally in 1995 the CW50 returned to Canada. This model returned to Canada after four years off, but since it wasn’t yet back in the USA, Yamaha opted to save costs sell this scooter in Canada using it’s European name of BeeWee or BW’s (an acronym for “Big Wheel Scooter”). Yamaha did revive the Zuma name in the USA when this scooter returned their for 1997, but by this point the BW’s name was established in Canada and so it has stuck around ever since. In the USA, Yamaha often called the reintroduced CW50 the “Zuma II” but it was mostly the same machine, including the same frame, body panels and motor. Moreso than any other modern scooter in North America, the CW50 kicked off the aftermarket performance scene.
The scooter used a vertical Minarelli motor, for which aftermarket parts were widely available globally and thus a new era of scooter culture was born with countless scooterists installing big bore kits and faster exhaust pipes. These parts are still widely available today, such as from and. The CW50 did receive a few updates over its run. For 1990, the Zuma gained a two person seat and footpegs to make carrying a passenger an option.
Also at this point, Yamaha shifted production from Japan to a Yamaha owned MBK factory in France. MBK also made a version of this scooter bearing their name called the MBK Booster. When it was reintroduced for it’s final years, Yamaha did release an revised version that was the same core scooter, but with a number of external updates - most notably new rims, a front disc brake (vs drum), and a larger rear rack. Generation Two: 2002 - 2005, 2008 - 2011 The YW50 was Yamaha’s replacement for the CW50, and this scooter was introduced for 2002. This model is commonly referred to as the bug eye Zuma, although third generation also shares these lights. This second generation Zuma became extremely popular - even moreso than the CW50 - and is supported by a vibrant of enthusiasts.
Sales figures are tough to come by, but Yamaha claimed on several occasions that this was the best selling scooter in both Canada and the USA. With this new generation came a shift in production from the MBK factory in France to a Yamaha factory in Taiwan with far more production capacity. The second generation of Zuma was all new model both mechanically and stylistically.
It was sold from 2002 - 2005 and again for 2008 - 2011. The hiatus from 2006-2007 was due to stringent new emissions controls, but it hardly felt like the Zuma was unavailable because Yamaha clogged their showrooms with 2005 models in advance of the legislation. There was hardly a time when you couldn’t find one in your local Yamaha showroom through 2006-2007. For 2008 Yamaha returned with the same YW50 but with a few extra emissions controls that unfortunately hindered performance a lot and thus are often removed by enthusiasts. It would have been nice if Yamaha had made the emissions controls less restrictive so that owners would keep them in place. Often 2008-2011 owners swap out their exhaust and adjust the carburetor to ’02 - ’05 spec to significantly boost power. This BWS/Zuma 50cc has many great attributes including its unique and rugged styling, a massive aftermarket scene and its powerful engine.
This generation of Zuma used a horizontal Minarelli motor (rather than vertical), for which aftermarket parts are also plentiful. It’s a great scooter for anyone who wants a sporty scooter to modify to go ridiculous speeds. Check out sites like, and for go-fast goodies. The switch to a horizontal motor allowed Yamaha to increase the size of the underseat storage area compared to generation one Zuma’s. On the downside, Yamaha equipped this scooter with a useless storage crack instead of a glovebox, such that overall storage capacity is a wash.
The gear slot is handy for holding a chocolate bar or tiny baguette but not much else. The other downsides of the YW50 are the inherent ones that come with having a 2-stroke engine. A lot of scooters are 2-strokes so it’s not really fair to bring this up, but the YW50 is being sold in a day when most scooters are shifting to 4-stroke engines (The Zuma was the last 2-stroke 50cc from a Japanese manufacturer).
Being a 2-stroke, you get great power but you also get reduced fuel economy, increased pollution, you have to buy 2-stroke oil and the engine life is shorter. If you want a 2-stroke scooter you’ve probably already got your mind made up and I can certainly understand why. Read more about 2-stroke vs.
