I have found a few problems with the installation of these levers on the 08 ST. Apparently Honda made a design change to the front brake master cylinder, using a different brake lever, and lever mounting configuration. The previous owner of my bike installed these items, and I never paid them much attention until I had them off for maintenance.
The 08 Honda lever is wider at the pivot point than previous models, and the adjuster wheel location has been moved away from the pivot point about 1//4 in.
***The Kuryakin lever works fine on the clutch side.There have been no changes on that side as far as I know.***
Honda lever is .880 wide,
Kury lever is .730 wide.
I,m not knocking these levers, they are a great mod, but they don't quite fit the 08 and later bikes. I have returned mine to stock.
