On second thought, Holeshot might be right here. I don't have my bike in front of me at the moment so I can't say for certain how the clutch cable fits in, but if I recall correctly the outer jacket does fit into slots on both ends and the way that fit happens is non-negotiable, meaning the benefits of a longer inner cable become irrelevant. I would try rerouting as Holeshot suggested.
The rerouting helped a little but not enough for me, might be enough for others or with a really sloppy clutch handle you might get away with it maybe... When I took it for a test ride later that day I pulled into a gravel lot with concrete barriers. I turned full right to get around the barriers and was barely moving because the clutch was pulled in just from the cable being so tight.
The VX bars are pretty high I measured about a 90-100mm rise (it's not really easy to measure it's kind of an eyeball guess sort of thing) the rox risers are about a 40-50mm rise so I bought handle bars with a 50mm rise to bring the overall height back down to stockish cable position I guess you would call it. I'm 6'2" with 34" inseam and have the seat concepts tall seat the bike feels perfect now.
For what it's worth I also tried to call motion pro and email them about a custom cable and they didn't answer either.
The handlebars and rox risers together are the best money I've spent on the bike highly recommend it. Vibration has been greatly reduced and they look tough as nails.
