Plus Six Rear Wheel Tone Ring for GTS 300 HPE (SI-KBPI0010)

Plus Six Rear Wheel Tone Ring for GTS 300 HPE

Plus Six Rear Wheel Tone Ring

  • '20 GTS 300 HPE (all variants)
  • '20 GTV 300 HPE (all variants)
This German manufactured rear wheel speed sensor pick up ring (tone ring) is configured to allow a roughly 6mph higher top speed than stock. 

This tone ring has redesigned slots which means that a more precise speed is transmitted to the ECU and Dashboard, removing the stock bike's speedometer error and thereby raising the top speed. 

No ECU remap* needed and no error lights, just take off the stock rear wheel tone ring and install this piece. (Rear wheel removal requires removing the muffler. Spare exhaust gaskets are sold separately as part number 8263885)

To make installation easier, we also recommend to buy new tone ring bolts. The Vespa part number is 667152, but we prefer part number AP8152137 due to it's deeper hex socket and sturdier overall construction (5 required).

*Please note: Once installed you'll have to recalibrate your traction control system (called ASR by Vespa). ASR Calibrations Instructions can be seen at this link.

**This part may not be legal for use in all states/territories. Check local laws before ordering.
