Dong Fang DF 250 RTB Bobber Information

[axa]

It would be a great little ride with, say, the Lifan 250cc v-twin (which is a copy of the Yamaha V Star 250 engine). Now I started thinking about putting different engines into the DF frame. The engine from the Buell Blast comes to mind. A 500 single based on the Sportster engine. I rode a Blast, and the one I rode had no problem hitting 80mph stock (the statute of limitations has run out on that crime). Or, what about the nice 650 single from the Suzuki Savage/S40?

Sounds nice in theory, but then you get the savage (or any other of these engines you mention) and try to fit in the DF frame, you realize its nearly as much work to fit the engine to the DF as it would be just to fit a hardtail to the savage...

Both DF front and rear engin mounts need to be moved/modified, The down tube also has to be moved and modded.

so that's exactly what i did... hardtailed the savage

Now if at the time I had another bike to ride, and my DF engine had already blown, it just have done the swap... but still i doubt it.
Its a hard decision to take 2 perfectly working bike off the road today, to have 1 in the future.

Though if you just happen to have a motor sitting around from a otherwise dead bike, then perhaps you can do it over the winter and waste nothing...
