# Service bulletin KTB2506

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

During quality checks, it was determined that the installed side stand spring does not meet our quality standards. For this reason, the side stand spring must be replaced on all affected motorcycles that are linked to this bulletin in Dealer.net. As part of the PDI, the routing of the engine breathing line should also be checked \(see Fig. 1 and Fig. 2\).
