I currently have two scooters: a 2009 chinese 125cc scooter that has so many electrical issues every fortnight that i'm contemplating contacting Guiness World Records, and a 2011 Yamaha 125cc Fuel-Injected Zuma which, after 7 months and 10,000km, and hasn't had one single issue.
The chines scooter costs something like $45,000 new, and the Yamaha costs $125,000 new. the chinese scooter has no parts support here on this island despite being sold at nearly every single hardware store or scooter shop on the island. everytime it breaks down, we have to borrow and scavenge stuff off other scooters to get it to work again. there is not enough web pages or mainframe servers available on this planet to list all the **** that has gone wrong with this chinese scooter which has a carburator vs the fuel injected yamaha. yes, i know, the the chinese scooter only costs a fraction of the yamaha, but if today someone offered me a brand new one for free, i would say, "No thank you!" and i'm not kidding.
The yamaha, on the other hand, i can find any part for it right off Amazon.com. that's not a joke. i can have any part here withine 5 days from the US. Yamaha Zuma's are very popular in the US and Europe where they're called "BWS". Also, almost any yamaha dealership here carries most things as well.
On the yamaha, i've been averaging 85MPG to- 86MPG with two--me and my girlfriend. on the chines scooter, i average bewteen 70MPG to 75MPG.
The yamaha i took on a 512km trip tour two weeks ago with a friend on a KTM 950SM; we did some light off-roading as well. i went from Cabarete to Samana to Las Galeras, and then took dirt roads outside of Las Galeras to Playa Fronton, and then back to Samana, then Las Terrenas for the night, and then back to Cabarete the next day. the total km for the trip was 512km and i averaged 89MPG.
