I made this for a guy who has his lower right leg amputated, he has a prostesis, but obviously, it can't operate the gear change on this old Triumph. With a hand gear change, he can change with his right hand (that is what he asked for). I haven't tried it on the road, but sitting on the bike it seems to work OK and it doesn't intrude too much on the riding position.

It looks good Jean.Is that considered a Jockey shift?
On a similar note I met a guy one time with the same amputation.He rode a Ducati 748 and shifting was performed by a solenoid with the Up/Down switches located on the left handle bar.

As usual you did beautiful work on that shifter. He must be really happy to be able to ride again!

As always, brilliant. Where is it pivoting on? More pics?

Thanks, I only took this picture, but what the guy wanted was something he could take off and return the bike to a stock configuration so I had a bit of fiddling to find attachment points. I used a ¼" thick steel piece that replaces a ¼" washer between the head steady and the frame, more support is added on one of the head studs which I drilled and tapped for a ¼" screw. The pivot is at the end of the ¼" steel piece. By replacing the stud and putting back the stock foot shifter, the bike can be returned to the way it was.

It is still pretty cold here, so I think he will try it out when it warms up a bit.

Nice.

Cold in Canada. Did not know.

Most guys just chop off the shifter mount end and weld a 3' piece of steel to it, then weld a bolt on top and screw on an 8-ball, doorknob or whatever. That is NASA tech right there...

Elegant robust solution that doesn't harm the bike, top notch, thanx for sharing. I could not see how it floated two pivots in the air like that w/o the behind the scenes details. May have to borrow the method.

It reminds me of a friend's Velocette LE. It was an early model and had a right-side hand shifter, not as elegant as yours. Unfortunately, the gearbox wasnt a traditional motorcycle positive-stop type, but a miniature automotive type with no sychronisers. You had to double clutch every shift! Needless to say, downshifting was VERY difficult - clutch in, lever to neutral, clutch out, blip throttle, clutch in, lever to lower gear, clutch out. Since the throttle was on the right handlebar, you had to move your hand back and forth like a one-armed paperhanger!
