Jeesh, mind boggles
Would it not better/easier to get a CRF450?
On the build, nearly double engine capacity, what about the frame?
Why not buy the CRF300 and insert the 301 big bore kit in it? (285? to 301cc)
Good luck in your research and decisions
I always have a small can/Fuel bladder with me when going into the Tankwa, an extra 5 or 10 litres does not weigh much, but will get you out of the dwang
