They claim to be adjustable but I can't see any means for adjustment in the pics - maybe the pegs are on an eccentric that allows some adjustment?  The price sure is attractive...

No FHE, but from the pictures they are indeed on eccentrics so they are adjustable.

Hard to tell how much range.

For DSS monsters? I see two Eccentrics. One for the foot peg and one for the toe peg.

I had some of these - well same milling pattern but I think motowheels was the original source. So there is a range of adjustment for the foot pegs, though it's not huge and limited to the circle defined by the eccentric. It's not like some others where there's a bit more variety - rizoma for instance.

The toe pegs are also eccentric

If the measurements are the same as the ones I had, even the most 'relaxed' position of the foot peg is higher than the stockers.

If you were not aware before, you'll need a pressure switch for the brake light. There's no accommodation for the stock clicker switch.

OK thanks.  I'll also need a way to hang my stock (cored/chopped) exhaust.
