Stella equal to which year Vespa?

I just wanted to know, since the Stella is modled after one of the Vespas… which year is it modled after??? Thanks for your help.
Here is the link to where the Stella is, but I don’t see that info anywhere on the web site. www.genuinescooters.com

I believe these scooters have a special catalytic exhaust, so I dont know if you can change the pipe. Any accessories from a PXEFL 125/150 should fit. In fact the disc brake and the shocks have been fitted by stella and are available for any PX

The reason why I ask is because I have one on order and I want to maybe put a pipe on it but I want to know what parts I can look for. The guy at the local scooter shop told me that you can take parts off of one of the style vespas (I assume PX), but I was wondering what exact year so that I can look into what parts I can use…

I believe they are LML`s and are based on the early PXEFL.

Thanks… that’s what I was looking for. I have seen where the Catalytic converter is and it’s mounted to the underside of the stock exaust. The good thing is that it’s mounted with only two bolts, just like a Vesap. The bad thing is that if you take off the exaust then you void the year warrenty. However, the stock exaust can be put on with two bolts just like a preformence one can. Anyway… Thanks again.
