Yes, you might be. I weigh 210 without riding gear. I carried about 45 pounds of gear. That's a total of about 270+ on the bike. I was on a less powerful Honda crf 250 L (I did upgrade the rear shock to work with that load). I did both the MABDR and TAT together- 8000 miles. The bike worked flawlessly. My point is the wr, same basic size/power category as the crf, will be perfect.
