Baja scooters seems like a pretty good scooters for very nice price, until they break down. Basically those are single use scooters. First couple of months were great, the scooter was pretty zippy and fast ( especially when you put more air in the tires, use premium gas, and synthetic oil) - mine went over 40 mph couple of times, although i had a wind helping me go forward. I used to ride it everyday to work - around 10 miles one way, and i used it during the weekends because it much faster to get around town than using a car. I was really enjoying it, then out of the blue the scooter wouldn't start.
I quickly learned that PEP Boys DO NOT provide the warranty or any other service for this scooter. If something brakes you will have to contact Baja Motorsport directly. They will try do do anything to avoid taking it back. For starters be prepared to spend 2 days waiting on hold, listening some BS message how great Baja service and support is from Patagonia to Northern Canada. I'm not trying to exaggerate. Once i was on hold continuously for three hours. I think they have only one guy answering all the calls because every time i managed to finally get connected, it was always the same person. They are not happy to hear about warranty repairs. They will keep stalling, ordering, backordering parts, calling you back, i mean NOT calling you back until you will give up. I was told by the service guy that if i need parts i should go to partsforscooters.com - this is where they get their parts too. Nice. I advise you to do the same, skip a middleman, plus they responded for my inquiry through an email pretty fast.
I went on fixing the scooter myself. Once you unscrew any kind of screw, there is a great chance you wont be able to screw it back again. Half of them snapped, on the other half the thread got worn out - they fell out themselves. All rubber seals are so thin and fragile, i advise you not to lift them. My fix was pretty simple, just faulty electrical connector, never-less i had to take apart almost every plastic part of the body and some other components. Be prepared that any simple repair even changing the spark plug requires taking almost half of the scooter apart. It's an engineering nightmare. All the wires are just "hanging" in there, some of them are just taped with electrical tape instead of using proper connectors. Screws are so soft you can bend them in your hands. Oh well, you get what you pay for. For $800 you can't expect much now days.
My advise is: don't buy this scooter. I know, the price is tempting, but keep it mind that year later it will be worth like $200, if you'll be lucky enough that it's still running. I would say, save some money or get a loan and get honda, yamaha or vespa. The resale value on those scooters is great and they are build to last. On top of that they have much better service, and its much easier to get parts.
PS. Baja Motorsport discontinued Baja SC50, many parts become unavailable even through third party resellers.
