If the BRP can't propel you through the "rock strewn creek" and other parts of your technical loop faster than the mini kx125, than you're too small and do not have the strength to ride the pig in anything but street like conditions. If I was faster on a 125, the XR would not be in my garage right now-plain and simple. It is a big/strong man's dirtbike. 125's and their weed-whacker like torque are best left to horse jockeys and pre-pubescent boys. Put up or shut your hole. Come to Ely Nevada. Bring your XR650R, and lets race through the "rock-strewn creek". If your man enough to ride as well as you talk, PM me and I'll give you contact information to get a hold of me. I'll even put you up for the visit, in a local hotel. As for the KX125, it has LESS torque than a weed-whacker. I weigh 220 pounds, and I am 40 years old. So much for your horse-jockies and pre-pubescent boys. Your problem with 125's is you can't carry enough speed through turns or up hills to keep one "on-the-pipe" (in other words, you can't ride). Come on out. Be sure to bring a GPS, a lot of talent, and many changes of underwear. Be extra sure to leave the excuses at home. Before you accept, be sure to consider how you'll feel after getting spanked by a 40-year-old on a bike that has less-than-half the power of yours. If you are a big/strong enough man to risk, and handle, some embarassment, lets ride. The xr650 is not the perfect bike for everyone. No bike is perfect. I looked at a lot of different bikes before I bought the 650. For what I do it is about as perfect as it gets. Power and reliabilty. The 650 is big and heavy but so am I. My number is 579. That's the combined weight of the bike ready to ride (302lbs) and my weight (277lbs). I never have been a two stroke fan. If somebody gave me a 125 I would sell it to come ride with you in Vegas. I wish I had the time off and the money to come out there and ride because I would love to ride that terrain. I'll be the first to tell you that 125's are hard to ride. That's why I'm not riding one. By the same token bring the 125 to Memphis. I'll ride with you. I don't care if you are faster than me, maybe you are maybe you aren't, because I will never be the fastest guy in race or on the trail but I promise you I will ride with you all day. Bottom line is I just like to ride and don't care what the other people are riding whether it's a two stroke or a quad. By the way the Harley is just fine. 4 yrs old and nothing but regular oil changes. So is the Polaris.
