Yamaha Zuma 50 Generations By Years

Here is The Zuma's Generation Years By Years . The CW50 and YW50 that will be our discussion as mentioned Below

Yamaha Zuma 50 First Generation (CW50): 1989 - 1990, 1997 - 2001

The beginning of Yamaha Zuma 50 was the ‘non bug eye’ version (CW50). The first Birth of Zuma is so cool as a scooter rider With a sporty look and fat tires. Also The Performance and agressive styling make Zuma quickly became very popular.

CW50 offering lasted just two years (1989-1990) After CW50 Begins to Sell in the US and Canada in 1989 before It breaks and stop The Production for a while. Besides, Yamaha Zuma 50 Also Very Popular In Europe after hiatus and it Finally developed by adding some features. YW50 Was the Next Generation Of Yamaha Zuma 50 CW50.

Yamaha Zuma 50 Second Generation (YW50): 2002 - 2005, 2008 - 2011

The YW50 was the next gen after CW50, Yamaha Zuma YW50 First Released In 2002. YW50 is referred to the Bug eye Zuma, though third gen has the same type of lights too. The Popularity Of 2nd Gen of Yamaha Zuma 50 or YW50 is overlapping the First Gen CW50 Supported By the Online based fans and enthusiast. It's impact to the Selling and it claimed as the Scooter Bike Best Selling in US And Canada That Time.

With this new generation, production has been moved from the MBK plant in France to a Yamaha plant in Taiwan with a much larger production capacity. The second generation of Zuma was a new model both mechanically and style. It was sold from 2002 to 2005 and again for 2008 - 2011. The 2006-2007 Yamaha Zuma 50 breaks the Production again due to new strict emissions controls, Yamaha Zuma 50 was unavailable because Yamaha clogged its 2005 showrooms with models before the legislation. There was no time when you couldn't find anyone in your showroom until 2006-2007.

For 2008 Yamaha returned with the same YW50, but with some additional emission controls, which unfortunately have severely impeded performance and are therefore often far away from the enthusiasts. It would have been good if Yamaha made emissions controls less restrictive so that owners could keep them. Often the owners exchange their exhaust in the years 2008-2011 and adjust the carburetor to '02 - '05 spec to significantly increase the performance.

This BWS/Zuma 50cc has many exceptional features, including its unique and robust style, a massive after-sales scene and its powerful engine. This generation of Zuma has used a minarelli-horizontal (rather than vertical) engine, for which the after-sales parts are also abundant. It's a great scooter for anyone who wants to change a sporty scooter to go at ridiculous speeds.

The switch to a horizontal engine enabled Yamaha to increase the storage area of the lower seat compared to the Generation 1 Zuma. On the back, instead of a glove compartment, instead of an unnecessary deposit, the entire storage capacity is a washing capacity instead of a glove compartment. The gear slot is handy to hold a chocolate bar or a tiny baguette, but not many others.

The other drawbacks of the YW50 are the inherent ones that come with a 2-stroke engine. Many scooters are 2 times, so it's not fair to do it backwards, but the YW50 is sold in one day when most scooters switch to 4-time engines (The Zuma was the last 2-1-2 gear from a Japanese manufacturer). As a 2-time, you get a great performance, but you also get a reduction in fuel consumption, increased pollution, you need to buy 2-time oil and the life of the engine is shorter. If you want a two-stroke scooter, you've probably already made your mind and I can definitely understand why. Read more about 2-Stroke vs. Four-stroke motors.

Yamaha Zuma 50 Third Generation: 2012 - Today

Almost everything new for 2012 (but very similar) is the Zuma 50F. This new Zuma has an updated style and a four-stroke engine, which shocks the tuning lovers. Despite the complete overhaul and the new engine, Yamaha has retained the YW50 model code for this third generation.

With the third generation, the style is completely new, but the changes are subtle. Some adjustments were made to his stylistic connections with the greatest Zuma 125. The alarm's headlights are still there, but most of the other parts are new. This new model has great lines on the back with a more shapely and fluid shape that improves compared to its already beautiful predecessor. The red rear spring and the front saddle are beautiful touches.

Perhaps in response to the love it or hate the headlights of eye bugs, Yamaha has released a unique headlight version called Zuma FX (USA) or Zuma X (Canada) for 2014 (below). The Zuma FX has a tidy front end reminiscent of the Asian program Zuma 125, giving it a more mature look. In addition to the new light, the Zuma FX adds "race inspired" handles, white rims and a 2-tone painting. The color options are listed at the bottom of this page. This version remained on sale for 5 years (2014 - 2018).

The 4 o'clock engine that will now power the Zuma will probably not be as good a lover of long-lasting performance who love pep on 2 time, but it is a large small engine that still has pretty good performance, advanced technology and excellent fuel consumption. This is a high-tech fuel injection, 3 valve, the liquid cooled engine, which is probably the best 4-time 50 o'clock engine in the North American scooter market.

This new Zuma is lighter than the previous Zuma at 2 lbs, but it's still heavy enough for a 50cc. It erases the mark of 200 lbs with a weight of 205 lbs. Most of the 50s are lighter than the latter, with the exception of metal vespas. The 180mm disc brake adopts the previous model, which is good news as this stopper works very well. The bit suspensions are new and the way down is 0.2" front and rear at 2.3" and 2.2" respectively. The rear tyre is also 120/90-10.

A small change is the carved fuel tank, which contains only 1.2 instead of 1.5 gallons. The 4 o'clock engine is smaller, but has a higher mileage, so the owners of 4-gear swingers have a similar range to previous generations, despite the smallest tank. The seat guard has been improved with this new model, especially due to Yamaha's wise decision to move the gas tank from under the seat to the inside.

This reduces the centre of gravity of the scooter and increases the seat, with the disadvantage that a fuel pump is now needed. The idea of moving the fuel tank in the bottom plate has been seen on other scooters over the past decade, and it's great to see how Yamaha has this idea of smart design. The new generation of YW50 still doesn't have a glove compartment, but a hook now replaces the largely useless "gear gap" found in the previous generation.
