I gotta be honest, I don't know squat about Stellas and Vespas. I talked to Pete this morning and learned a lot. Genuine makes the Stella, it's one of the several bikes that they make. Genuine is based in Chicago and has nothing to do with Vespa.
Just wanted to weigh in on this, as it is mostly correct, but is lacking a few details.
Genuine actually doesn't make any bikes, they are an importer, just like Bintelli or Wolf import Znen scooters. The Stella scooters are actually manufactured in India by LML, and are sold in the rest of the world as the LML Star. LML and Vespa do actually have a history together, but that's another story.
The other Genuine scooters (Buddy, Blur, Hooligan, Roughhouse) are made by Taiwanese manufacturer PGO. As we all know these are high quality scoots, so kudos to Genuine to choose a good product to bring to market. Also, it should be noted that while Genuine doesn't actually do any manufacturing, they have been able to make design changes to some scooters so they better fit into our market (e.g., the Hooligan).
As I understand it PGO had a huge hand in the engine development for the 4t ,, I like it,, it's quirky funky weird ,, kinda like me,,, it's made for me,,, lol,,, it's a scooter so 60 mph and under is perfect and it's where this thing lives,, if I wanted a fast bike I would have gotten an R6 yamaha and made it into a streetfighter,,,for almost the same money,,, or an fz6 an even easier conversion but slightly different mill,,, not quite as powerful still a fabulous bike,,, I rode yamahas for years and was the exclusive weapon of choice,,, they make a real nice machine,,
The Stella 2T is pretty much an LML Star that was sold under the manufacturers name overseas instead of the Genuine Scooter Company that carried the scoot here in the US. A good many Vespa PX series parts will interchange with it. I know this first hand. I built a Vespa P(TX) 200 engine for my 2004 Stella 2T last year. I kept the Stella's electronic ignition feature but otherwise kept the engine stock Vespa. I have to do my 2 cycle oil when fueling up. The engine doesn't have the oil injection mechanism that was on the scoots original 150cc engine or on some p200 and px200 engines. It is also strictly kickstart only. That I don't mind. willc.
