Nope. Don't know what they call it. Have seen another in pics. I like it too. I like to ride with just the front of the foot planted and the heel free. The shifter is in the way. Want to keep all the original part in case the next owner wants them or I have to revert back for a reason like yours.
I understand your issue. Because the Triumph shifter is NOT splined, it can not be adjusted downward out of the way of your heel, as I have done with my Kaw V2K. I found a splined shifter from a Thunderbird that worked for my R3R and eliminated all the linkage crap.
The distance from the engine spline to the shifter toe location does varry from the R3R to the Standard & Classic so, measuring your bike followed by a comprehensive search will be in order. Good fortune with your mod!
