Seat bushing replacement for Honda Part # 17611-HA5-000. Save yourself $5 and print it for under 20¢ in material.
Personally used on a 400EX but can work for all others with same part number (300EX, 250R, 700XX, etc). I've been replacing them about once a year with very minor wear but may vary with ride time/style, material brand, infill, etc.
Should be able to be used for 17611-HP1-000 on the 450R/ER as well, but may take a little modification.
Can be printed with TPU/HSTPU from 20-80% infill depending on how much cushion you want, I found the sweet spot to match OEM to be 30%.
