To start off with, the OE part is trash (see pic.). It is mounted too near to the cover, had gouged the cover and was difficult to use with boots on.
The Hammerhead (Part# 25-03-00 +420mm) is a perfect replacement. It lengthens the gear shift lever, provides more space between the lever and the cover and is much easier to reach with boots on.
But the fit is not as simple as it looks. The easiest method would be to remove the gear shift lever but I gave up when I saw how far the lever clamp is hidden within the frame.
The pivot pin for the OE tip is 1mm slimmer than the Hammerhead pivot pin. The OE pivot pin is crimped and had to be drilled out and the hole drilled to 8mm. The Hammerhed spring does not fit into the fork on the OE gear lever and I used the original spring. Of course I lost the circlip holding the Hammerhead pin in place ... but Hammerhed must have known I would and there ws a second circlip in the pack.
The replacement took longer than expected, but was well worth the expense and the effort.
