Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The motorcycle goes into limp home mode and throws several codes which are all related to the throttle position sensor. This has happened to me several times at various speeds, RPM's, and throttle positions. I spoke with multiple mechanics and they advised me to first clean the connector at the throttle body. Cleaning the connections worked and I was able to clear the codes. After riding about 150 miles the same issue happened again and I ended up stranded in the middle of no where. This time I could not get the codes to go away. …”
NHTSA complaint #10626557, filed 2014-08, 29,500 miles“The throttle by wire connector hooks in behind the breather. Due to the hard turn of the connector going into the plug it bends the wires resulting in them breaking over time. This causes the motorcycle to lose throttle and go into limp mode causing me to very closely come to getting run over on the highway. It happened multiple times on the highway, turning. And on city streets.”
