I want to put a set of motocross bars on my CBR125. To do this, I need to replace the stock bars as well as replacing the entire front headlight section. Then I need to move my gauges onto the forks and try my best to get the controls (throttle, clutch, brake, high-beam/signals, kill-switch) onto the new bars. I know it can definitely be done, because I've seen pictures and video of other people who did the same thing.
This is pretty much what the bars will look like when I'm done:
This is what they look like now:
Here is a video of a guy on a CBR125 with dirty bars doing wheelies:
I may also need to order longer replacement cables, but I wont know until I find out.

The first step is removing everything I don't need. Then I need to find a way to mount the bar clamp onto my triple clamp. This can be done by drilling directly into the flat part between the fork tubes. I'm not sure how well that will work with the embedded Honda symbol in the way though. It looks to me like the people who put the bars on their CBR125s drilled right into it, so I'm assuming it isn't a problem. If this becomes a problem, then I may need to find a way to make a custom pinch bolt, which would be attached to a flat piece of thick aluminum that would bridge the fork tubes together. Then I'm sure I could drill the bar clamps into that without a problem.
I decided on the tapered bars because I couldn't find a 7/8" bar clamp, and I just like the style of the standard sized bars. So I'm going to use the 1-1/8" over-sized bar clamp, but with tapered bars, so it will fit at the clamp, but will still have the standard 7/8" for grips and controls. I don't plan on using handlebar risers, unless the bars need to be higher to make it over the bolt on each of my fork tubes.
I also read that you should put rubber washers on each side of the bar clamps to help with vibrations. One thing I'm a little confused about is whether my brake, throttle, clutch, signal/high-beam switch, and kill switch will all fit on the mx bars. I'm not sure if there will be enough space to fit, and whether all of them will properly clamp on the 7/8" bar. I'm also not sure how to extend the wires and cables, but that should be the easiest.
Lastly, I may need to pick up parts to make a custom mount for my gauges. They are currently mounted onto the front headlight/cluster and the frame in front of the tank. Instead, I need them to be on the forks so that they pivot with the wheel, along with the new headlight. I still have no idea what I'm going to do for the custom mount, but once I'm able to see everything in front of me, I'm sure I'll figure something out.
That's all I've got for now. I'm looking for constructive criticism and any possible suggestions.
