yamaha zuma 125

It doesn't crank over until you let it cool When this happens, the scooter doesn't respond when you press the start button. Sometimes when you go for a long ride on a hot day, the fuel pump will get too hot and if you shut off the scooter and try to restart it, then the fuel pump won't operate. One known issue with the Z125 that is possibility related to inadequate cooling, is that the fuel pump can cease to function when it gets too hot. There are some advantage to air cooling (simplicity, light weight) but I still prefer the steady temperatures that liquid cooling ensures.

This is a curious decision because Yamaha has recently added liquid cooling to their two 4-stroke 50cc models. The fuel injection and 4-valves are downright cutting edge (in engines this small), but strangely Yamaha opted to skip the liquid cooling and instead keep the temperatures under control with a fan. What’s interesting about this new engine is that it’s an odd blend of new and old tech. It wouldn’t surprise me to see the Vino 125 get a short case version of this engine soon.

The Vino 125 now lags this scooter in power, fuel economy and ease of starting. These engines are entirely different. The new engine is supposedly quite a bit faster than the 125cc engine Yamaha is still using in the Vino 125. It’s got decent storage under the seat (5.5 gallons), rugged looks and a new fuel injected, 4-valve engine.

The YW125 seems to be one awesome scooter. The initial response has been quite popular with BWs/Zuma fans, new scooter buyers and even Honda Ruckus fans who have been clamoring for a 125-150cc version of that scooter for some time. For 2009, Yamaha responded to enthusiasts cries to design a larger version of the popular BWs / Zuma scooter.
