When I was riding my TLR250 Delwiche in 1986 in the Belgium's trial national championship, there were a few young guys riding on TLM50 and one boy on mono-shock RTL50.
In the port of Bangkok were I go sometimes to find bikes and spares parts for TLR, TLM and RTL, there is one of these tlm50 for sale. Since 2 years, nobody is interested and at the not negotiable price of about 400
