Im building aluminum framed CR500 supermoto based on a 2004 CRF450R chassis. Even though this isn't my first supermoto, I'm super excited. I've had a couple really fun KTMs, the last being a KTM 525SMR, but that bike was set up for smaller kart tracks, high maintenance and really expensive to fix. After the motor needed to be freshened up and the parts bill was 2/3 of what the bike was worth, it sat. Eventually I came to the realization that it was worth a lot more in parts than whole so I parted it out. Meanwhile, during the last year or two I've been doing more and more track days on my GSX-R 600 Suzuki. I've been having a lot of fun with that... but I miss the supermoto. This summer I had a chance to ride my buddy's highly modified Husqvarna 510SMR at NY Safety Track and that made me decide that I *HAD* to have another one... I wanted a new supermoto. This one though had to be fast, but it also had to be easier and less expensive to maintain than my old KTM. I wanted it for track days and possible racing on road courses, not the tight motard/kart tracks I used to ride. I want to ride it on road courses like Summit Point Shenandoah, NY Safety Track and Jennings GP. I want the bike to run 120 mph. And so the project began... Finding a chassis I started with a street legal CRF450R in supermoto trim I found a few hours from my house. Its a very clean, low hour unmolested bike. The seller was really bummed after the sale that I was gonna tear it apart, but I know the end result will be well worth it. As soon as I got the bike home I had it titled and tagged before I took it apart. Before I tore into it though I had to take it for one short ride around my neighborhood. I was impressed. It had more power than I was expecting! Verified on GPS the bike would do 103 mph as I bought it. Not bad. (for what its worth, the Trailtech speedo was within 2mph of the GPS top speed) <iframe width="420" height="315" src="//www.youtube.com/embed/cKwHLC7WH7A" frameborder="0" allowfullscreen></iframe> Parting it out After that first ride I pulled it into the garage, put it on the lift, and pulled the engine, carb and exhaust. I sold them all off, ending up with just a rolling chassis. Time to find a CR500! I then began my search for a CR500 engine. At first I was thinking I'd go just for a motor but after some research and seeing what complete motors were selling for I figured I could get a complete running bike for not much more. In addition that would also get me the carb, exhaust, ignition and throttle. Before too long I found my bike, a 1999 Service Honda CR500AF. I got it from a guy who bought it four years ago and due to a bad knee was never able to ride it. It just sat in his warehouse collecting dust. A nice bonus was that it came with a supermoto wheelset and a bunch of new Honda hardware. Since the bike hadnt been run in four years I took it home and changed the oil, cleaned the carb, put a fresh plug in it. After it all went back together all it took was three good kicks and the engine was running . and damn, it sure sounded good! <iframe width="560" height="315" src="//www.youtube.com/embed/opKmXsztY5U" frameborder="0" allowfullscreen></iframe> Sell off what I don't need to fund the rest of the project Now that I knew it would start and I could run it through all the gears I then pulled everything I needed (engine, carb, exhaust, ignition, throttle) and then list the rolling chassis for sale. Learn new skills I should also mention that while all this was going on I also managed to find some time to have a good friend start teaching me how to TIG weld (I'm already pretty good with MIG). I'd like to weld the CRF frame up myself, but Ive still got a LOT to learn so I think Im just gonna have to let him do it. Ill do all the cutting and fitting though. What's next? I'll be ordering motor mounts and aluminum stock for the frame this week. The swingarm bushings I need should be in by the weekend, so I hope to have the motor at least sitting in the CRF frame by next week. With that being said, that's where I am now with this project. Stay tuned for more updates!
