Nothing simple about designing this copyrighted design kit at all. Oodles and oodles of different STAR arcs, angles, radii, major and minor diameters were tried on multiple bikes to get the best feeling, best performing design for each bike. In the end, it's what Marc demanded in "shifting feel" and response. The EVO STAR kit does the impossible - it makes shifting quicker, virtually eliminates missed shifts, removes clunkiness AND is easier and more reliable to shift than stock. Fixes notchy ZX10s and lazy shifting Ducs, Aprilia's, Kaws, CBR's and Gixxers. Hayabusas stop shifting like a truck and now shift like a dream on street and track, with or without the clutch - at 2nd gear, in-town "cruise" and when "bangin' downshifts" into that 160 to 20 mph corner or "trying for that last 10th, "bang into second" shift at the drags.
