Looking at the photos, it looks like an SVM tank. The frame does not look like TL 125. The front end probably IS TL 125. ??swingarm lengthened or not TL. Just some thoughts.

I have a Montesa Cota 247 (?year) that I am starting to rebuild. I am in the Trials Club of Canberra, but I have not yet been active - no bike! I hope to change this in 2013.
