Hi BB,
the TA 650 does NOT have a Catalytic Converter.

It has a hot tube which with the aid of a air introduced into the exhaust cleans up the emissions. Different system to CC and can't be harmed by leaded fuel.

Leaded fuel coats the CC and stops it working I does not clog them up. It does not make any difference on a bike because they don't have to be emission tested.

The TA will run on anything the locals use I have use 76 octane without any problems. Check out what local measurement is used, UK uses RON and some coutries use AKI ratings which is about 4 points lower, ie 89 AKI = 93 RON. There are other ratings.

Where are you going to that may have leaded fuel ?
