OK, I am considering buying a used 500 EXC and would like some opinions on them from folks that have owned them. I currently have an '07 EXC450 that has served me well for dual sport and I'm sure would continue to do so but, this opportunity has surfaced so..... Troy, I believe you have a 500 and have also owned a '07 450, how do they compare? How about power delivery with the EFI? Any problems with them overheating? Will the rear subframe support a giant loop Mojave? Any thoughts/opinions on the 500 would be appreciated. Figure I might as well blow some $$ on bikes rather than watch it swirl the drain in the stock market. :evil: Thanks.

xrnut now owns my 2013 500 EXC. I stole his 2014 300 EXC in trade.

I had no overheating issues. I used my Mojave bag on the rear without issue. I had issues with the bike smoking a little even though it ran perfect and had great compression. Therefore, assumed valve guides and had a professional rebuild it. In hindsight, I might have just left it--it ran great and had plenty of power.

HONESTY? I liked my 2007 450 EXC better. Despite having lower weight (in specs), to me the front end of my 500 felt a lot heavier. Perhaps it was something a guy could resolve with proper setup, but I'm a moron about how to setup a dirtbike.

I disagree with Troy on the moron bit. Crazy? Yes. Moron? No.

I have a '17 450 EXC & a '19 500 EXC. The 450 is snappier, faster turning, easier to ride off road and feels much lighter. I have the 450 set up for off road romps. Zero issues. The 500 is still geared stock (tall) & is more of a handful except for street or gravel where it excels. Zero issues with it as well. I would say if you are going to do dual sport with limited trail riding the 500 is better. I'm getting 60 MPG on the highway when I behave myself. The 450, geared down 3 teeth in the rear, gets about 45 MPG since it is never ridden sensibly. If you are going to do more off road stuff (Colorado mountains come to mind) the 450 would be my choice. As you can see from my post in the Ride section I just rode a 200 XC-W in the desert south of Las Vegas. I would have taken the 450 everywhere there. I would have left the 500 at home. It would have worn me out. I have a rack on the back of the 500 which helps strengthen the sub frame but I would not be reluctant to toss a Mojave on it without the rack. I still would not overload the sub frame. If you have more questions just give me a call or email me.

"Harvey",
Let me add to my comments. The FI has made my bike much better for off road riding as well as on road riding IF you increase fueling to make up for the extremely lean maps that KTM is required to supply to road bikes. With my '17 450 I was able to get the off road Euro map installed before KTM shut that off and get a rare 450 specific header and exhaust for that year 450 (from England). The 450 is great everywhere, on and off road. It is not valued more than my dog, but close. I don't think you should be worried about FI. The only caution is that you run your bike in the winter to keep the FI nozzles free. Eric Green at Cycle Zone said it is extremely expensive if you let one of them sit without running them. That is the same that I had with V-P race fuel. Run it every 2 weeks or clean jets. Run a FI bike every month or assume you will be cleaning nozzles and possibly a fuel pump. There are zero issues with overheating with proper jetting. If you want a stock bike that is lean then it will overheat. If you don't you will have to correct the FI map. If that is not an option on the bike you want then you will have to purchase a Vortex or equivalent ($700), and add an exhaust capable of working with your new fueling map. In my opinion, an opened up stock exhaust should work.

I used one of these racks on my 500 and it has survived crashing.

The only FI bike I have owned was a '00 Buell S3t a number of years ago. I just ran fuel stabilizer in it and let it sit thru the winter and had no problems. Can't you do that with the 500? What happens if you maybe install a petcock/shutoff valve in the fuel line and turn the gas off and run the injectors dry if you are putting it away for an extended period of time in the winter? Or does running the injectors dry screw something up?

My question about the FI was more centered around the power delivery down low if riding single track. I realize the bike is not meant for tight stuff but every now and then I'd probably use it that way. I've read that some people put throttle cams on the 500's to tame them down and maybe that's because they are not used to the power of the 500 and the FI characteristics, I don't know. I'm used to riding a 300 KTM in the woods and as you show it respect and not whiskey throttle it you will be fine. I suspect the 500 may be the same way.

I don't know, my 450 has been pretty much wash and wear, almost like a DRZ, probably should keep it. I guess you have to ask yourself, do you want to leave your high school sweetheart wife for a hot stripper??? Thanks for the replies guys.

I've never used fuel stabilizer so I cannot comment on that. I just like to ride my bikes and doing so during the winter is a pleasure for me even if it is 20 minutes of running around the neighborhood. Eric Green at Cycle Zone has seen lots of bikes with plugged fueling systems. He would be a good resource for more information. My '13 500 was a pleasure in the woods with very easy control, especially compared to my 300 XC which I looped a few times. The '19 500 exhibits the same characteristics. Very easy to ride really fast and with as much throttle as you want to grab. My '17 450 is in between these extremes. This is given my experience and penchant for craziness. In the end if I had to live with only one bike it would be the 500 since it is so easy to do dual sport riding and scream in the woods. If anything I would like a "reverse" throttle cam on my 500 that was even more aggressive. My carburetor version '13 would stall sometimes if I grabbed a handful of throttle way down in the RPM curve. My FI bikes have the same tendency but it is most easily remedied with the Vortex where I just adjust the low end fueling with a cabinet screwdriver in 5 minutes, unlike messing with jets. In my mind you already have the hot stripper with the 450. If you want the high school sweetheart for the long haul (my choice, believe me!) then the 500 would be the way to go.
