I agree with Jmo, in that KTM will want to win with their engine. However I think some of us are looking at the problem from a privateers perspective.
The new 450 rule will, for me, mean that the top teams will have a lot more for the mechanics to do. I applaud Sherco for their attempt at the Dakar this year, but was horrified to hear that they were stripping and rebuilding the motors every night!
You can be sure that next year KTM will be rebuilding motors everynight to make sure their 450 gets to the end. This to the outside world will make the KTM engine look strong and reliable. Proven in the Dakar!
This doesn't help anyone in the short term, but hopefully will lead to more reliable 450's in the future.
Personally I still don't understand who the rule change is mean't to help. The 450's still go fast enough for you to get hurt, and the future privateer will now have a less reliable bike, which probably needs an engine change on the rest day.
