WR= Wide Ratio

YZ = Yamaha Racing - don't ask why the Z means racing, they started to put the Z on their race bikes back in the 70's

TT-R= started life as IT (2 stroke International Trials - 60's) but the 4 stroke equivalents were called TT bikes (60's and 70's). In the 70's they became TT-R - R stands for Racing because many parts were shared with the YZ (Z=Race) line of bikes.
