Chimera Adjustable Stretch Extension Blocks will allow you to easily stretch a 1st, 2nd, or 3rd Gen Honda Grom 125 (2014-2023)! Easy to install! Simply slide it into the end of the OEM swing arm and bolt it to your desired length! Fully machined from T-6061 aluminum! Features built-in caliper bracket stopper and stainless steel hardware!

Available in Hard Anodized Black. Made in the USA!


  • Adjustable stretch length! Length could be adjusted from 4" to 6.5" (+/- 1/2" depending on the chain tension adjuster)
  • Easy chain adjusters! Easy to access chain adjuster with a 5mm allen wrench that is at the very end, reducing the time or fuss of having to adjust the chain tension. It would also keep the chain position at the same location unless you adjust the tension screw on the adjuster blocks. 


  • A longer chain will be needed! 130L - 134L depending on how long you would like to stretch it!
  • For the 2022+ Grom. the OEM axle might be too long, therefore it will have some slack. You could run the original OEM silver chain adjuster position plate OR pick up some axle spools/sliders to fill the slack. A shorter aftermarket axle will also work if you decide to go with that instead
