Note: Running a 6" wide rear rim on the Grom or Monkey will result in approximately 1" of offset toward the throttle side — this is a known characteristic due to chain clearance and does not affect ride performance. For 2023+ European MSX/Grom models with rear ABS, this hub will not retain ABS functionality.
