Jenny is spot on here. The Crf450L isnt designed for two up riding. It doesnt even have pillion footpegs. Except from that it has 7,6 liter fueltank which with luggage and lets say an imaginary pillion would take you maybe 150-175 kms if ridden very easy. Thats a patetic range imo. It also requires oil change every 1000 km and valve check every 3000 km. Even though one could probably stretch it a bit it is ridiciously short intervals. Its a enduro competition machine and never meant for long distance riding and never meant to be ridden two up.

Riding two up on bad roads requires what Jenny writes, strong subframe and comfortabel seat. I would also add suspension that can handle such conditions, far from all bikes comes standard with that.

In my opinion riding two up on gravel roads isnt much to aim for. Sure a firm gravel road isnt any big problem and can be enjoyable. But as soon as the roads starts to get sandy, gravelly, muddy, stoney, bumpy or full of potholes - the fun disappears very quickly. One can for sure manage a short stretch with such conditions, but long stretches, days, weeks - good luck!

If you really want to get off the beaten track maybe consider getting one bike each. That will make riding in rough conditions so much easier and enjoyable. And remember - lightweight bikes too! If you insist to ride two up on one bike it make more sense to stick to better roads, not totally off road.
