Here are the forks from Doug Polens 1992 Bike #2 (DP922). The chassis number of the bike is ZDM888S*001350* (one digit away from bike #1). This bike is in the Ducati Museum and is now incorrectly stickered and labeled as a 1993 Falappa bike. Both of these 1992 Polen bikes originally had Team Police sponsorship/stickers.
The bike that is being auctioned as a supposed 1990 Falappa works bike has a chassis tag that is completely different from the two 1992 Polen factory bikes. It also doesn't have the large aluminum preload adjuster knobs that the 1992 factory bikes had on the top of the Ohlins forks. The chassis number is also way too low to be a 1992 bike.
The bike looks like a standard 1991/2 customer 888 Corsa that has been stickered up to look like a 1992 Falappa bike.
The only thing that leads me to believe that it may have some Works parts on it is that it has the 6 pin diagnostic connector on the left side fairing stay so the factory team could communicate with the injection ECU
