Think I'm coming round to the thought of drilling my yoke.... not having any luck finding any risers with 10mm bolts.

Does anyone know the max height I can go without having to change any cabling etc? I heard 4" was max somewhere?

Much more choice if I can look at harley/style risers.

Reckon someone should make more off the shelf goodies for the America/speedmaster.... not liking Triumph's prices.
