We are pleased to offer a new CDI for the Vespa ET4 and LX150 with carburetor, and a new CDI for the Vespa GT200. These CDIs eliminate the Immobilizer circuit, and are individually tested as part of the quality control process. Unlike most CDIs that bypass the Immobilizer circuit, your turn signals still work. Mention this ad in the comments and we will refund your shipping or buy more stuff and get free shipping.

We also offer them for the Piaggio Fly, BV200 and BV250 with carburetor, LT150 and Italjet Torpedo 125 and 150.
