Hmm, I've been on a Suzuki TS. So I take it that the TSR is a trials version of their road bike of similar name. Does seem like a tidy bike to be fair.
I brought one of these a couple of months ago but it was in boxes as i got it as an unfinished project, i wanted to build it up, but it would have cost way to much cos spares can be hard to find. Im breaking it on ebay atm...to fund the rebuild of my money pit dt! lol
I rode a couple of ts 50's when i was younger, and a ts125x, but never the tsr, i remember seeing them about though. Rare these days..
