Trial bike as well equipped as it is finished, the 125 TY YAMAHA was designed in broad outline by former trial champion Mick ANDREWS. Its geometrical frame and the use of special alloys in the production of certain parts made it extremely handy. Its very flexible engine equipped with a well-staged six-speed gearbox and very good suspension allowed it to drive in the city. HELLER offers you the type 1K6, which appeared in 1976, with a larger silencer than that of the initial model type 541, and satin black engine casings instead of polished aluminum.
