DLR - Di Lione Racing (from memory). Many MotoGP 125 and 250 bikes use DLR cans
They are italian, I think the cans you got are called DLR SP cans (kevlar can). They also make one called DLR GP (carbon, a little shorter than the SP). I have a SP and 2 GP cans (only using one on my Aprilia RS125)
I might have their address somewhere. Haven't been able to locate a web-site or even an email.

Personally I like them. They weigh next to nothing
