Happy Trail manufactures strong luggage mounting hardware and aluminum panniers. Their mounting kits are also usable with GIVI and Pelican cases.
GIVI manufactures topcase adapters which replace the plate on the Transalp's handy rear carrier. They also produce crashbars.
The E200 Monorack plate for *Monokey* topcases is available from Midwest Cycle Supply, AZ Motorsports, and Happy Trail. The E200 is for 1988-1996 applications. Note that the E211 may also be listed, but is for 1997-1998 applications.

The TN363 crash bars are available from AZ Motorsports and Happy Trail. Mounting these to a US-spec Transalp requires longer bolts across the front and minor trimming of the bike's plastic radiator guard.
