I am fabricating setbacks by stacking and staggering two 1.25” Motopumps risers. Anyone have an opinion as to whether I can just re route the cables and hoses for this approximately 5” longer reach? Procuring and installing longer hoses and cable is something I’d prefer to avoid.
Have you read this thread about Motopumps risers? https://www.vfrworld.com/threads/bar-riser-blocks-aka-handle-adjuster-plate-08r70mjmd10.46851/ Looking at the 24mm motopump risers I have on my bike, I'd say you are going to have problems with both brake and clutch hoses and the throttle cables. There isn't a lot of extra length on those, probably just enough for the 32mm risers. Another problem you may encounter if you raise the bars by 2.5 inches. They are probably going to foul on the upper cowling. Not sure on what you mean by staggering them, but if you move the bars back farther and higher, then I reckon you have no hope of the brake/clutch hoses and throttle cable of reaching.
