LOL. You're too lazy to read through the entire thread for context, and you criticize the OP's decisions and my comments. Funny. Anyway, the DR650 is just one example. That is in reference to the comment that a dirt bike frame can't handle the power of a GS500 engine. I just pointed to one example of a dirt bike with similar power. I gave a specific response to a general and inaccurate statement. The other comment was that dirt bikes don't have to lean a lot and a reference was made to arena cross. Okay. Because so many people in the world do arena cross. Dirt bikes lean. A lot. If you actually ride them. As far as flex, anything made from chromoly steel has flex, because chromoly steel has flex. Chopper frames have flex and it's a good thing. The flex keeps them from cracking. Aluminum doesn't like to flex. It cracks. But steel, steel can flex. I raced mountain bikes for many years and it took me a long time to buy into aluminum frames (I quit doing it before carbon fiber became so big).Not sure who “you guys” are and not sure how you know it’s a DR650 frame unless my reading comprehension has gotten worse, which is a possibility or he mentioned it on another thread. Don’t most dirt bikes have all kinds of interesting flex built in? You tell me, I don’t really have any desire to read up on them. Let’s assume yes. Combine that with a (presumably) first attempt to make major modifications to a frame. USD forks, a swingarm that isn’t likely go to flex behind that engine, fat tires etc etc. and my guess would be that for a street bike... or whatever he uses it for, it will flex more and not in a desirable way.
OP, did you plot out the rake and trail before you started.? If not, you may be in for a surprise. Even if you did plot it out, the change in ride height will have changed that. You may want to make further changes or swap out the triple, to get more trail. Might want to add a steering damper, but better to have them set up so they don’t shake to start with.
I preferred chromoly because it flexes. Aluminum framed bikes with no suspension shattered your teeth and I didn't want to have suspension to counter the stiffness of the aluminum frame. Also, I'm pretty sure feather bed frames have a wee bit of flex in them. Funny how so many people love feather bed frames, since they suck so bad and are inherently going to kill you because they have flex. I might be wrong about feather bed frames, but it doesn't matter. Basically, you guys are wrong that a dirt bike frame can't be a good base for a bike with excellent road manners. I showed you an example of a supermoto DR650. It has good road manners. In the pic it is leaning. A lot. I built a similar bike from an F650 frame and power plant. It's amazing in the mountains of Western North Carolina. Not really a dirt bike, the stock F650, but look at their frames. If you want to show up with your amazing sport bike and race me in the mountains on my F650, I'll be happy to ride. I'll even do it with my Karoo tires. See if you can lose me, or even keep up. The OP's bike may have issues, but it won't be because dirt bikes can't be made into great street bikes.
