Common Problems and Complaints of Modern Vespa & Piaggio Scooters. RECALLS too!

SMALL FRAME FAMILY OF MODERN VESPA SCOOTERS.The ET2 is a great scooter. Under powered? Too slow? Not if it is used the way it was designed to be. It's VERY reliable. The important thing to remember when buying a used ET2 is to ensure it has been maintained properly. I get ET2's in the shop with worn out spark plugs, filthy air filters, rollers worn down to the metal core and THEY STILL RUN! The ET4 is another great Vespa. It is BULLETPROOF! The most common thing to fail on an ET4 is the headlight bulb on the early models. They used an incandescent bulb which doesn't hold up well when exposed to bumpy roads. Later ET4's have two separate halogen bulbs which do much better. Front tires on ET4's can develop a "cupped" wear pattern. I've yet to figure out if this is due to under/over inflation, an unbalanced wheel or faulty shock absorber as most of them by now have 2 of the 3 causes present.
The LX50 is a 4stroke scooter, it's slow and under powered. Most common problem has been carburetor related. Adding an in-line fuel filter will eliminate clogged carb issues. Being ridden regularly will also improve the relationship you have with your 50cc. While employed at the dealer, every LX50 I prepped for sale needed to have its carburetor removed and cleaned out BEFORE it would idle and run right. If your LX50 is a 4 valve model, contact your dealer regarding this recall- "Ignition Control Unit Replacement NHTSA Recall 11V-603"  

The LX150 was somewhat problematic at first due to frequent dead batteries, fuel gauge never reading accurately and to a much lesser extent, fouled spark plugs. When the LX150 came out, it had a "small" YB9B battery installed, this battery was later replaced by the much more powerful YTX12BS. Which fixed the problem. If you have an early LX150 and the battery has been replaced MAKE SURE you have the correct plastic battery tray underneath to avoid the battery squashing or rubbing through wiring insulation. The wrong wire touching the frame can cause the wiring harness to melt, catch fire. Inaccurate fuel gauges upset MANY customers but Vespa never issued a fix and left the explaining to the dealership or, in my former employers case, left the explaining to the mechanic (me). Anyway, develop a relationship with your LX150, pick a day, once a week, to top off the tank, record the mileage, record how much fuel it takes to fill the tank and you'll soon figure out if you're refilling too soon/late. If that's too complicated for you, rely on the low fuel light, when it starts to flicker start thinking about finding a gas station, when it is on solid, GET TO A GAS STATION! Fouled spark plugs are a rare problem caused by shipping LX's originally destined for hot climates to cold climates. If you live in a cooler climate you want to have a Champion RG6YC. Hot climates use an NGK. The "clicking" front brake is a non issue, caused by the holes drilled in the rotor. Still, new Vespa owners are often concerned about this noisy brake. Finally, here in San Francisco, we occasionally have noisy, groaning clutches (driven pulley assembly) caused by getting overheated going up our very steep hills at a slow speed or in stop and start uphill traffic. Again, this is not a safety or reliability issue. An annoyance yes, but nothing to be concerned about. Customers often ask me what the fix for this is. I tell them the clutch pucks and drum can be de-glazed but the noise will come back as soon as the clutch gets hot again. I used to tell them to avoid steep hills but it's near impossible here in San Francisco.
LARGE FRAME FAMILY OF MODERN VESPA SCOOTERS.The GT200 is a pretty solid scooter, the main problem is the clutch (driven pulley assembly) Again, in SF, the hills combined with the additional weight of the GT200 can quickly cause a noisy clutch. The larger Vespa scooters- 200, 250 & 300 all suffer from oscillation- a wobbling of the handlebars experienced WHEN NOT HOLDING ONTO THE HANDLEBARS FIRMLY. Please, HOLD onto the handlebars, don't just rest your hands on them.  

The GT250 has had issues with the fuel pump but the most common problem is the voltage regulator. A healthy charging system puts out 13v-15v. When the voltage regulator fails, the voltage can spike to 26v. This will cook the battery, cause bulbs to blow and the fuel pump to knock loudly inside the gas tank. It's an expensive fix and a fairly common one. There was a recall on SOME GTS250's. It replaced the exhaust manifold. Some GTS's developed exhaust leaks and hot exhaust gasses would melt the rear brake hose. Contact a dealer to see if your GTS250 needs the recall performed. "Recall 07V-253 GTS250ie Exhaust System Repair" This recall affected less than 3000 GTS scooters.  

The GTS300 had an early fix because of incorrect fuel pump wiring harnesses. So far, the 300 is proving to be another bulletproof Vespa.
THE SMALL PIAGGIO  

The PIAGGIO FLY is actually a very well built scooter, the only problems I have encountered on FLY's are problematic carburetors and premature leakage from the front suspension. Other than that the FLY is a solid well built scooter.

  1. My 2012 Vespa LX150 has 208 miles on it and the battery is good, the electric power in on but the scooter won't start. The oil light and transmission light are on and the scooter won't turn over to start. Any thoughts?

  2. I face the same problem. After changing to a bigger battery size YTX12-BS as suggested by the blogger, problem solved! The kick start is a hassle I rather use a cable to jump start the bike!
