Default Advice on riser positioning

Before I drill my top yoke (triple tree) I thought I would ask the wisdom of CF first.
I am not sure whether to go for a single bolt riser or double bolt set up. If consensus is for a single bolt, which position should I drill, red or black? I would feel better with a two bolt solution and think that there is enough metal to accomodate that type of riser.
I will be purchasing some ally slab and cut it to fit into the pockets under the yoke to help spread the load of the riser bolt/s.
Advice appreciated guys. Thanks.

I make mine with 2 bolts , if you were using one the ideal position is prob going to interfere with the rib on the underside

I shall take some measurements and go for two bolts as one can go in the red spot and one in the black spot, either side of the rib underneath, which looks to be the obvious solution and will place the bars practically in the middle of the yoke. Packed out underneath the top yoke with a carefully sculptured piece of ally JB welded to the yoke, washer, flanged Nyloc nut and the job should be a good'un.

Anything else I should be aware of as well as ensuring the bars don't foul the forks and the risers being sufficiently wide apart? Cheers.

Default Re: Advice on riser positioning

for a clean look...albeit underneath the top yoke...I could use single bolt risers through the clipon screw holes which are within the beefier part of the yoke. As riser bolts tend to be 12mm from what I have seen, drilling through the clipon screw hole will leave one side of it quite thin...is that an issue? Any other issues I am not seeing with that? cheers.

it'll set the risers quite far apart, check the centre of your bars is wide enough

I hadn't thought about that Yan...doh! I won't be drilling anything until I have the risers and bars, but need to take these things into consideration.

I'd go 2 bolt, for reasons above. Also creates a lot less stress on the holes you drill; with a single bolt, you might get ovalization over time, have to clamp things tighter, etc. Clamping things down with two spaced bolts is always more durable than one (maybe fatter) bolt.

So the answer is both - you drill both red and black, assuming the risers line up.
