Evening Kev. I used to run my XBR cafe racer on a pair of Hagon shocks, reasonable price and definitely decent shocks for the money. I used to do some fairly “brisk” riding on it from time to time and never had an issue with the shocks. They definitely used to do shocks for The cb250rs. Not been on their site for a few years so not sure if they still do.
Best of luck with it
Cheers, Michael
