Will a 250r engine fit in a 87 250x frame?

Yup, yup, yup. Don't expect it to just drop in though. You'll probably have to fabricate some mounts and modify a few things.

Done the RM 250 thing Too much vibration, Will break/crack frame, but they are fast. I was told to use rubber or such mounts except for the main Motor bolt, and mount that without anything else, normal. I personally never tried that. Also I used a Quadracer chassis, so it bolted right up. But a few tricks to take out some vibration are silicone in handlebars, and steering shaft. Just fill them up, helps alot.
