Very good quality.
Using this on a custom bike. Old British bike, BSA with "modern" Yamaha front end and levers. Everything fine at the front end except I had to use the nipple from the old cable as the solder nipple on the new cable was too short.
At the gearbox end, I had to have the terminal end of the ferrule turned down slightly to fit into the original BSA clutch adjuster.
So for me, it wasn't really a kit but a length of inner and outer with bits to modify.
