So on my way to work this morning, I come to a stop sign maybe about 100 yards from my parking garage I notice a really bad sounding grinding noise coming from the bike. I'm almost certain its not the front or rear brakes. Almost sounds like its coming from the engine. I stopped and the noise only comes when the bike is in motion. Even when its turned off I walk it in neutral and the grinding is still there. Could it be my transmission is screwed. Its a 2008 Buell 1125r. The bike still under warranty. Any suggestions are helpful. Won't be riding home obviously. Great way to start a Friday. | ||

Put the bike up on stands and spin the wheels to figure out where the grind is coming from... You might have done something as simple as worn out your brake pads or have a bearing going out. The good news is if you get the noise in Neutral, odds are it's not too expensive of a part. The most likely worst case IMHO is it might be a loose rotor/stator or clutch basket nut, but if you hear it in N with the motor off, I doubt that's the case. Let me know which wheel the grind is coming from and we can start to diagnose from there. | ||

Jdugger, I recently had the rear brake pads replaced at my last service so I can possibly rule that out. I don't have a stand here at the moment, but working on getting my truck here in a bit to haul it to the dealership. Maybe it is a bearing like you said. | ||

T, You can lean the bike on the kickstand if you are careful, lifting the rear wheel into the air. Then have a buddy give it a spin and listen... | ||

If you find the problem is that a rotor nut or stator fasteners are loose, and nobody's been in there working on it, then you need to file an NHTSA complaint. | ||

I had a similar type of grinding noise that suddenly appeared while riding. It increased/decreased with speed (not engine revs) and was present with engine on or off. Turned out, one of the allen bolts the secured something behind the primary belt pulley cover had come loose and contacted the belt teeth. So when you roll the bike the contact made a grinding noise and increased with speed. I tightened that lose bolt and all was well. Check if the drive belt is contacting anything. You need to put the bike on a rear stand or something that will allow you to spin the back wheel. | ||

dropped the bike off on Friday and it looks like its a wheel bearing issue. Thanks guys. | ||

That happened to me too on my Firebolt. It happened after I hit the POTHOLE FROM HELL. But the noise started slow then increased with ferocity over a period of several days of commuting. It wasn't just nothing one day, then bad the next. |
