Hello, I once had a 1979 Yamaha TY 50 in special version. It was then imported grey by a dealer in Hamburg (from Holland?). The most important features were: – 5 instead of 4 gears (1st gear down!!) – horn as well as glare and driving light, on which 50-s then a novelty and the switches in the original grip – papers for a mockick (Tempo 40), but ran from delivery already measured 72 and no one could prove technical changes… – front 18 instead of 19 u nd rear 16 instead of 17 inch wheels – 16-er instead of 14-er carburetor and open tailpiece on the exhaust Are there still copies of it? Have fun!!
