Affected Models: A specific range of:

  • 2021 RS 660
  • 2021 Tuono 660


Concern: As part of our ongoing commitment to improve product quality and to provide the best possible customer satisfaction, it has come to our attention that a specific batch of crankshaft connecting rods have been found to have a defect.


Cause: SPT srl the supplier of the connecting rods installed on the vehicles, has found that a specific batch of connecting rods were produced without the correct heat treatment and could become compromised and break. This situation could result in a stoppage of the engine, which affects safety and may lead to a crash.


Correction: On affected vehicles, the engine will be replaced. Please determine which vehicles in your stock or sold by you require this recall.

  • Update the vehicles already in circulation as soon as the customer requests it.
  • Update the vehicles in your stock, which must NOT be warranty registered or delivered to the customer before the replacement of the engine.


We are currently in the process of notifying the Customers who have already purchased the product in question directly. We would appreciate your full cooperation to ensure that the necessary replacement procedure necessary is performed as soon as possible.

The restoration of customer motorcycles MUST be prioritized over stock motorcycles.


As usual, the list of frame numbers involved in the campaign is viewable in the section Campaigns / Campaign Reports of the PWM warranty management software suite.
Customers can also check for themselves if their vehicles are subject to this recall campaign from the “Customer Service” section of the website

The intervention to be carried out on the motorcycles involved will be the complete replacement of the engine only (specific code CM2966115 without Air box – Engine ECU – Engine wiring harness – Canister etc), therefore the original components of the vehicle must be reused.
