Therefore I understand that 1.5 yokes "close" the steering and shorten the distance between axles. My tiger cub with montesa forks (parallel yokes, centred axle) feels quite heavy and does not turn very well. From the information that I got, it seems that a Tiger cub with original frame goes better with 1.5 yokes. According to Carl explanation, I guess a more closed steering makes it lighter in front and facilitates turning...
