Top yoke

 Lall Engineering have done a good job drilling and machining the top yoke, as asked. I had them mill into the top yoke, down to the level that it had been carved, so that the large washer (sourced with the Triumph Street Triple bars, thanks ebay uk) sit with 3/4's of the washer touching the raised yoke and therefore distribute the pressures put into the bars on to the yoke, rather than having the bar riser bolts taking all the pressure, and sheer forces. I bought Triumph Street Triple risers as they only have one bolt needed to go through the yoke. This reduced the footprint needed and made it possible to have risers and street bars.


I was looking to reinforce the underside of the bars due the the yoke being, in my eyes, thin on metal. However after looking at the yoke on my Ducati Monster it turns out that they are all made at the same thickness of aluminium. 


Once fitted and tightened with the 28mm handle bars bolted in place the structure becomes ridged and all is good :)
