Yamaha Raptor YFM660R ATVs
Check against the official notice below — it lists the full affected range.
Yamaha Motor Corporation is reminding owners of 2001-2004 Raptor YFM660R ATVs about a previously announced recall. The affected models have "660R" on both sides of the bodywork and "Raptor" on the rear fender, and are available in various color combinations including blue and white, black and white, black and red, or red and white depending on the model year. During extended high rpm operation, vibration from the engine and driveline could cause the rear master cylinder reservoir to agitate, allowing air bubbles to enter the brake fluid and reducing rear brake performance.
Yamaha sent notification letters to registered owners on February 27, 2004. The company is offering free repair through authorized Yamaha dealers. If you own one of these ATVs and have not yet had it repaired, you should stop using the ATV immediately and contact an authorized Yamaha dealer to schedule a repair appointment. If your ATV has already been repaired as part of this recall, no further action is needed.
