Decided to increase the gearing of my xtrs 125 by going up a couple of teeth on the front and it has transformed the bike. Now I can cruise on the with fewer revs and less vibration. On a hill I used to struggle up in 5th I now just ride up comfortably in 4th instead.
My only complaint is the Yodel delivery driver went to the wrong house. I got an email saying they were sorry they missed me and had left a card. But that was a lie. I found out that the people who live at the same number as me but on the next street had told him exactly where my house was, but he had just driven off anyway. So I wasted a day waiting in for nothing. Yodel said they couldn't do anything and I would simply have to hope the driver the next day got it right.
