Didntstickthe1v1 nahh ducati desmo gp20 doesnt have one, honda rc213v doesn’t have also they use 65 ish degree V engine. The Crossplane engine bikes are yamaha not sure about suzuki tho. And Aprilia im not sure since they renewed their engines to 90 degree. Sound changes because of their different engine configuration and layouts. Also KTM uses V4 not sure about the degree tho.
