Took a lot of weight to balance both tires

Hey Andy...I've run across this and have asked that the tire be rotated 180 degrees to reduce the weight.

The tires look good.  I've been shopping for a rear for my Z1, many online stores are out of stock on the 120/90-18

Stev-o there was no yellow/red dot on these tires so maybe that also added to it. Front took less weight than the rear

Easier to fit 120 than 130 with stock chain case.
My K6 had a 130 in the 80's when rear should be wide.

It was  OK since most use of it on long holiday with 2 persons and luggage 3000km away and 3000km back home, mostly high speed highways.
