Photo Info: Yamaha TY175B in original colours (Competition Yellow and White). This bike holds one of the earliest frame/engine numbers for a TY175B (525-000144) The Yamaha TY175B started production with frame number 525-000102, some preproduction models appear in early literature/magazines etc. without frame numbers according to comments made by others. Delivered new in Western Australia and first ridden in competition as a dealer supplied bike I purchased it in late 1978 or early 1979.
