Anybody tried this? I fitted one to a triumph Bonneville today, works surprisingly well, no loss of movement, which is the problem with the extended lever idea.
 
Tried it long ago Marty, it collapsed within a couple of weeks. The internals are not strong enough to cope with the heavy Laverda springs. The effort to compress these doesn't disappear...

It has the same loss of movement once leverage ratios are altered, you can't beat physics!

It's very popular in the classic trials scene here, it offers better control over old, grabby clutches, because of the movement loss.

Can't get my head round it, Marty.
If the handlebar lever is clipped into 1, it'll take less effort/give less movement on the clutch pushrod.
If the handlebar lever is clipped into 2, it'll take more effort/give more movement on the clutch pushrod.

To lighten the pull, handle bar lever attaches to #1, clutch actuator to #2. The 3 offered ratios are altered by shifting the pivot pin. Of course, if you're so inclined, you could always use the opposite sides... lots of people intentionally make life hard for themselves. :rolleyes:

IIrc, it was either the pin or the internal lever that broke at the pivot. Good idea, well made but simply too weak for our needs.

I have one of those gadgets in my shed, I was desperate to stop the pins and needles in my left hand from my, and maybe not every other Laverda, insanely hard clutch pull. I tried one of those gadgets before seeing the article in Classic Bike by Phil Todd on his extended clutch arm kit. I rang Phil from Oz to ask about the details of his kit. So back to that featured gadget, it worked for a week and I thought HALALUYA I found a fix. And then I broke the short cable it came with. Before finally making and fitting Phil's kit I would brake 3 or 4 clutch cables a year. That's how hard my clutch pull was. After fitting Phil's kit I might break a cable once in probably the last 20 years.
 
I was going to give one these a whirl. I couldn't figure out a neat place to locate it out of sight on an SF1 though so didn't go through with the purchase. Maybe there's somewhere a stronger home made version could actually be bolted to the frame out of sight. That would be nice. I'm not keen on the extended lever sticking out and there's nothing I can do at the bar end is I have Lucas batwing switchgear
 
There was one on a 750SF at my local auctions, the gizmo didn't look newly fitted to sell. It was noticeably easier to pull in the clutch than that on my own SF. However there was also a 750GT at the same auction which had no such device and standard levers at both ends. It was even easier to use! Maybe shagged clutch springs as it couldn't be tried running, or possibly just a better routed and less sticky clutch cable.
