Here's a really well done Transalp combination. It's owned by Dirk from Salzwedel/Germany (no eMail address, sorry), and it was spotted at the ITT'98. The sidecar is, AFAIR, a Jewel, front telefork is replaced by a swingarm with double Koni shocks. Sidecar connection was done by a subframe. Wheels are 14'' car wheels.
