Following a range of high management meetings, the Csepel Motorcycle Factory introduced the luxury version of TLT.

Designated the TLB, the new model featured a fully enclosed engine cowling, and two-tone colour finish. Production costs, however, restricted numbers and scarcely 3 thousand machines were produced. The covered-in PANNÓNIA was mainly produced for the German Democratic Republic and modified accordingly, the standard flywheel magneto unit was replaced by a 60 watt Dynamo.
An incrased engine output was also achieved with the introduction of the domestic 27 mm power jet carburettor.
