Everything was from a 2002 Aprilia RS125, even the mud guard suits the look.
The yoke that came with them on purchase had been drilled, as seen in the first photo, and had added risers for flat/upswept bars.
Now although probably a better rising position it's not exactly caferacer and I wanted a stock look so I bought a new old stock top yoke off an 07 RS125 Aprillia which looks like a machined version of the original (cuts outs- and different colour)
I ground off the clip on hangers as the Aprillia bars are VERY pricey just for tubes and sprayed with black wrinkle paint (baked in my oven hehehehe sorry to my misses in advance)
The yoke then looked made for the bike and the CNC 50mm clip ons I bought.
Used the original steerer off the CD175 as it has more girth than the Aprillia one.
(Bottom yoke of the Aprillia bored out to accept the Honda steerer)
This also means you can use the original Honda bearings or upgrade to tapered needle rollers - as I did, and also means to messing about with the top yoke bore wise as the Honda tube narrows at the top and the heights are fine.
For the axle I needed a 20mm Alu bar, machined some spacers and hollowed and internally threaded the other side (again to look stock)
Also attached a brace from the disc calliper mount on the fork leg to the drum casing. Again as the RS only had one calliper- she looks stock
