It's funny how we all have different experiences with bikes. I've never been as impressed as I am with my Strom. 37,000 miles and not a single issue, the most dependable bike I've ever owned. My stator will probably go out at some point, I'm expecting it, I just hope I'm not in the middle of nowhere. I do carry a battery pack. Might even start carrying a spare stator and yes Suzuki should do something about it.

I hadn't thought about normally used rev range and stator failure. What occurred to me is normal voltage level. Maximum voltage before the R/R caps the top can range from 13.4V to 14.8V and still be an accepted value from most places I've read. The Suzuki service manual says between 14.0-15.5V at 5000rpm which I consider ridiculous. I've noted that at https://www.stromtrooper.com/general-...tatements.html

I'm wondering if systems that run closer to one extreme or the other may be prone to earlier failure. Higher voltages may come from stators with higher outputs which could produce more heat. Lower voltages may occur because the R/R cuts off early and shunts more power into heating the stator. My last two 650s ran a corrected voltage anywhere over 3000rpm at a little more than 14V, right in the middle of the range, and never gave a hint of a problem. The 2007 did many miles out west at 6000rpm but the 2012 rarely exceeded 5000rpm.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

If your theory is true GW then I might never have a failure as my voltage has never exceeded 14.1 volts at any RPM. My meter is connected to the heated grip connector if that makes any difference.

My understanding is that just about every Japanese (and Triumph) bike uses Shindengen R/R.

If this is the case then other manufacturers should experience similar failure rates.

Maybe we should look at other bike web sites as a comparison.

I don't know the manufacturer of the stator which as I understand is the item that actually fails although people also change the R/R as a precaution. Do the R/R's actually fail?

R/R failure is very rare. I hope people are only changing them if they test badly or are going to series types to save stators.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.

On my VFR R/R's failed often (I ended up buying a cheap one off ebay as a back up. I've had the same thought as v-tom in regards to suzuki's my friend has a gsxr600 and rides it gently, her stator failed. the previous owner of my vstrom used to ride the snot out of it and had zero issues with the stator. small sample size but i know many people do not ride higher in the power band.

i ride my 12V hard and the stator failed at 10K.
