I cannot comment on the TLM260, but as I own and ride regularly a 1985 RTL 250 , 1988 TLM 250 and a 1986 TLR250, I can give a fair review of these... As everyone says the RTL 250 in Rothmans colour sounds and looks stunning. Mine is in original spec, and its biggest disadvantage is the stance. As Woody says it feels like you are doing a handstand at times and takes some getting used to. If you persist with it you do adapt and it is a brilliant bike to ride, and the engine is a stunning piece of engineering. The TLM250 looks pretty, but ultimately suffers with similar stance problems to the RTL. Obviously as a 2 stroke it is a very different power characteristics and is fun to ride in dry grippy conditions, but I find an absolute bitch in the wet!! My TLR250 is by far the easiest to ride of the three, but it is now far removed from original spec....Modified frame , whitlock swinging arm, loads of weight saving measures...Its now a brilliant bike to ride, less power than the RTL, but will still put many a modern bike to shame!
