Well I finally received, fitted and tried the Hippel 30mm clutch slave cylinder. The lever has a lighter pull, the gear change is easier, I can find neutral with the motor running, I can push the bike backwards in gear & I have better clutch feeling at the lever.
It was well worth the money, a big thumbs up from me for the Hippel 30mm clutch slave cylinder on my 2022 Beta 250 evo.
