I make hydraulic clutches mostly for triples and a few for twins. The one in my racer has been in there over ten years without a failure but as with a cable, life is dependent upon abuse. Which ever actuation, with the same ratio (lever movement to clutch lift) the force to move the clutch pressure plate will be the same. The difference is the frictions. Since friction in the hydraulics is only at the master lever pushrod angled to the piston (small), both master/slave seals and angle between the slave piston and clutch pushrod (ideally zero), it is generally less than a cable rubbing along the length of a sheathed tube and the ball/ramp being pulled sideways by the cable. You can make a cable-ball/ramp system lighter to hold by using a non-linear ramp. A steep initial lift followed by a shallower ramp. The force to hold the lever in would be as light as feather but it will feel like pulling the clutch cover off with your bare fingers on the initial movement. The hydraulic system is self adjusting. The cable can make the clutch drag or slip if you get it wrong.
been running PSP kit on my TR6 bobjob for the last 4 years, savin up to put one on my T140 - hydraulic clutch has been really smooth and ultra reliable for me

Three years ago, at the Toys for Tots run, we got stuck in traffic. And on a hill. Not unexpected since 8,000 bikes showed up. I would have loved a hydraulic clutch then. My hand hurt for most of the day. Tiger, poof, or whatever, the hydraulic would have been a great relief.
IMHO hydraulics on the frame side of a Britbike are for the effete, not sure what you would call them in Sweden but in Australia they are referred to as poofters.
Well, IŽm asking on my wifeŽs behalf since she is the one riding the Triumph, and sheŽs got a weakened left wrist due to a horse riding accident in her teens. Poofter could be a word for it, as she does prefer male genitals, but since I know sheŽs 100 percent female it really doesnŽt hit home.
DonŽt know about Australia, but here in Sweden prejudice is a privilege of the ill-educated and blatantly ignorant.
I've had one on my Tiger 650 for three years now. No problems. A bit difficult to install due to clearance issues in the gearbox outer cover, but nothing a Dremel tool couldn't fix. I got mine from the UK, but can't recall who sold it to me. It looks like LP Williams sells it PSP Clutch. I think it was worth it and would buy one again.
